Eradication of TB: Discussion

I remind Members and witnesses to turn off their mobile phones. Witnesses giving evidence from within the parliamentary precincts are protected by absolute privilege in respect of the evidence they give to a committee. This means that a witness has a full defence in any defamation action for anything said at a committee meeting. However, witnesses are expected not to abuse this privilege and may be directed to cease giving evidence on an issue at the Chair's direction. Witnesses should follow the direction of the Chair in this regard and are reminded of the long-standing parliamentary practice to the effect that, as is reasonable, no adverse commentary should be made against an identifiable third person or entity. Witnesses who are to give evidence from a location outside the parliamentary precincts are asked to note that they may not benefit from the same level of immunity from legal proceedings as a witness giving evidence from within the parliamentary precincts does and may consider it appropriate to take legal advice on this matter.

Privilege against defamation does not apply to publication by the witnesses outside the proceedings held by the committee of any matters arising from the proceedings.

Members are reminded of the long-standing parliamentary practice to the effect that they should not comment on, criticise or make charges against a person outside the Houses or an official, either by name or in such a way as to make him or her identifiable. Parliamentary privilege is considered to apply to utterances of members participating online in the committee meeting where their participation is from within the parliamentary precincts. Members may not participate online in the public meeting from outside the parliamentary precincts. Any attempt to do so will result in the member having his or her online access removed.

The purpose of today's meeting is for the committee to received an update on the eradication of TB. The committee will hear from Mr. Conor O'Mahony, principal officer ERAD division and veterinary medicines at the Department of Agriculture, Food and the Marine; Dr. Damien Barrett, superintending veterinary inspector at the Department of Agriculture, Food and the Marine; Mr. Teddy Cashman, chairperson of the deer management strategy group; and Dr. John Griffin, chairperson of the scientific working group of the TB forum. They are all welcome. Their opening statements have been circulated to members. I will allow five minutes to read opening statements before proceeding to a question and answer session.

We will start with the Department.

Mr. Conor O'Mahony

I thank the Cathaoirleach, Deputies and Senators for the invitation to appear today. We welcome to opportunity to discuss the TB eradication strategy. The Department is acutely aware of the financial and emotional stress associated with TB breakdown, which causes significant hardship to farmers and farming families. This Department is committed to the objectives of the TB eradication strategy and programme, which aims to reduce and ultimately eradicate this disease in Ireland. The importance of Ireland's TB eradication programme in underpinning farming family income should not be underestimated. As a country that exports 90% of its livestock produce, access to international trade markets is fundamental. It is a requirement of EU trade law to have an eradication programme. This enables Irish farmers to access the EU Single Market for our cattle, including calves, meat and milk. It is also a requirement for access to third country markets, where our exports have substantially grown in value and volume in the past ten years. It is noticeable that in several cases, TB is a significant consideration in the context of trade and certification requirements. A cost-benefit analysis report of the TB programme carried out by Grant Thornton in 2021 estimated that in economic terms, 78% of the benefits of the bovine TB eradication programme relate to private goods, while 22% accrues to public goods. This further emphasises the importance of the programme to our ability to trade internationally in dairy and beef products, which in 2022 amounted to €6.8 billion worth of dairy products as well as more than €3 billion worth of beef exports. That was in addition to the live export of more than 200,000 cattle and calves.

It is important to stress that in recent years we have been at an historically low level of TB prevalence, notwithstanding an increase in the past seven years. The focus of everyone engaged in dealing with TB is to reduce these levels even further and to move towards eradication of the disease. However, there are several challenges. TB is a challenging disease to control and eradicate due to several factors. The relative contribution of each of these factors varies from farm to farm. They are the movement of cattle with undetected infection, residual infection in cattle previously exposed to TB, inherent limitations of the tests, a reservoir of disease in a protected species - namely, the badger - and inadequate biosecurity practices. It is therefore important that farmers are empowered and supported to make the best choices for their own circumstances to protect their cattle from TB. It is critical that they are given practical advice based on scientific research about how they can reduce their TB risk and that they are given relevant, useful information about their own herds, their own cattle and neighbouring risks so that they can make any management changes, which may be necessary if they wish to avoid the costs and stress of a TB breakdown. This involves making informed decisions about the purchase of cattle and maintaining good overall herd health. The advice on how to reduce TB risk in a herd has remained generally consistent over many years and we continue to encourage farmers to act on it utilising a broader range of communication tools. Stakeholder endorsement of this advice, through the TB Forum, is hugely important in encouraging farmers to take active steps to reduce their TB risk. We are providing information and advice on the practical steps farmers can take to reduce the risk from badgers by a range of means including SMS texts, videos, leaflets and farmer meetings. By combining these practical farmer-led risk reduction actions with the policy of badger vaccination to prevent breakdowns and targeted licensed badger removal where necessary in response to spillover from badgers to cattle, we can greatly mitigate the risk of TB at the wildlife and cattle interface. Vaccinating badgers reduces the transmission of TB within the badger population and thereby reduces transmission to cattle. This protects cattle and reduces losses to farmers while safeguarding a native protected Irish wild species.

Previous EU audits and research related to the Irish TB programme have highlighted a lack of stakeholder involvement as a key impediment in achieving eradication. To help address this and in response to the developing disease situation, the Minister established the bovine TB stakeholders forum, in May 2018, in line with international best practice on the governance of animal health programmes. Its mandate is to develop evidence-informed policies that can eradicate TB while respecting the principles that were outlined in the national farmed animal health strategy. These include working in partnership, acknowledging roles and responsibilities, reflecting costs and benefits and prevention is better than cure. These considerations ultimately resulted in the TB eradication strategy 2021 to 2030, which was published in January 2021. The key actions of the strategy are preventing spread from herds with a high risk of recurrence, enhanced actions to clear infection from extended breakdown herds, addressing the risk from inconclusive animals, action plans for areas with increased localised TB levels, aligning with changes in the EU animal health law TB regulations. They further include reducing the risk posed by badgers, reducing the risk posed by deer in certain areas, tailored, simplified communications, clearer messaging of the risks of TB transmission and how to address these and biosecurity advice delivered to farmers with a focus on practical, clear and effective actions to reduce risk and incentivise risk-lowering behaviour.

I turn to the current disease situation. Almost 5,000 herds have suffered a TB breakdown in the past 12 months in comparison with fewer than 4,400 in the previous 12 months. Epidemiological data analysis suggests the reasons underpinning current levels of TB are the expansion of the dairy herd, the resulting increased levels of intensive cattle farming and the increased movement of cattle. We have also seen a substantial increase in the number of reactors with 27,800 being disclosed in the past 12 months in comparison with just below 23,000 in the previous 12 months - an increase of almost 5,000. In driving strategic change in the TB programme in Ireland the Minister, Deputy McConalogue, has consistently highlighted the critical role of stakeholder collaboration. Reflecting this, implementation of the TB strategy is being facilitated by a governance structure designed to ensure all perspectives are considered. The TB stakeholder forum is supported by three working groups – scientific, finance and implementation. Each group has an independent chair to deliver on their specific terms of reference. The working groups all report back to the forum.

Delivering the TB programme in any given year represents a massive logistical operation achieved through the co-operation of farmers, private vets and Department officials across the country. In 2022, more than 9.5 million individual animal TB tests were completed in more than 100,000 herds. The overall cost to the Exchequer of the TB programme, excluding staff costs, has increased from €52 million in 2021 to €57 million in 2022, and currently stands at €65 million to the end of November this year. In that time, the primary drivers of increased costs have been compensation payments to farmers and veterinary fees associated with additional testing. For many years, Ireland’s TB programme has been financially supported by the EU. However, EU support for the TB Programme has now ceased primarily because of funding pressures for other emerging diseases throughout the EU. Support was €9 million in 2018 and in 2023 we received €1.6 million in respect of 2022, the last year for which we will receive funding. This funding gap will have to be addressed by the remaining stakeholders and is a potent reminder of the need for collaboration and the urgency of action to decrease the disease levels.

The TB strategy sets out how the Department and stakeholders will continue to engage on the issues impacting on TB levels in Ireland, which will involve some difficult choices. By building our policies on a foundation of science and by providing practical science-based advice, which farmers can act on to reduce their risks, we can together focus our efforts to protect cattle from infection and farmers from the stress, uncertainty, and costs of a breakdown. To make further progress towards eradication, it will be necessary to take further steps that impact on the source factors, which maintain infection in herds. These will mean a need for greater controls on certain aspects of the programme, which will challenge stakeholders to engage with some difficult choices. If appropriate additional measures to reduce TB are not supported by stakeholders, this will likely have an adverse impact on future TB trends and the drive towards eradication. Most actions set out under the current TB strategy have either been implemented or are advancing well towards implementation. To make further substantial progress on TB in the 2023 to 2025 period, additional steps to build on the current strategy will be needed. Options were presented by the Department to the TB Forum and discussed with farming organisations for consideration at meetings over the past three years. The options presented included voluntary or mandatory informed purchasing, which would allow farmers better inform their management decisions in respect of their herd risk management when they are purchasing cattle, voluntary or mandatory risk-based trading, incentivised risk lowering behaviours and disincentivising risk elevating behaviours, reducing spread between areas using contract rearing risk mitigation and restrictions on movements from high to low TB areas. Other options included dynamic risk estimation at herd and animal level, supporting quality TB testing using gamma interferon blood testing and spatial tools to identify each group of cattle, reducing spread from high-risk herds by restricting older breeding cattle and confining TB exposed cattle to controlled finishing units and a regionalisation approach to eradication and control.

Based on these stakeholder discussions, the scope of what the farm organisations are prepared to accept as next steps became clear. While more progressive measures, such as informed purchasing, risk-based trading and increased restrictions on high-risk herds or animals, would be expected to lead to a sharper reduction in TB. However, these do not currently have stakeholder support.

We now have the building blocks in place to implement additional measures to the existing programme that can lower disease incidence and result in fewer farm families having to endure the challenges associated with a TB restriction. We are committed to constructive engagement with all stakeholders in helping the farming community. I sincerely hope that the next time we address the committee on bovine TB we will be able to outline a positive picture of reducing TB incidence and a trajectory towards eradication. I welcome questions from members to myself and my colleagues.

I thank Mr. O'Mahony. I ask Mr. Cashman to give us an update before we go into questions and answers about the IDMSG's strategy on deer management.

Mr. Teddy Cashman

We launched a report last week, which was pretty well publicised. We have gone through a process over the last 12 to 14 months on deer management. We set up the deer management strategy group in September of last year. We were set up by the Minister for Agriculture, Food and the Marine, and the Minister of State at the Department of Housing, Local Government and Heritage who has responsibility for the National Parks and Wildlife Service. We started the process pretty much by looking at what had happened before, which was the previous forum that had existed from about 2014 to 2018. The previous forum looked at all the different aspects of the impacts of deer but did not address the solutions or what needed to be done. However, that forum did a lot of work on TB and analysis as part of that report. We had not really concentrated on the TB one in this particular process because the work had been done. From that perspective, the statistics are there to correlate that one.

Next, we set up a public consultation. That was very important from the point of view of getting the public's view on what should happen around deer. We had a broad ranging interaction for the consultation. We have about 1,500 respondents which is quite a lot for a public consultation and they were: 757 rural individuals; 360 urban individuals; 314 farmers; 283 landowners; and 177 others, foresters, ecologists, academics, non-governmental organisations, public bodies, farm representative organisations, trade bodies, research organisations and local authorities. From the point of view of the committee, we had a few interesting outcomes that were very relevant as we went further into this, which were what are the main impacts that people feel the deer are having, and what are the most prevalent ones or the ones that are having the biggest impact. I will rank the impacts in order of size: biodiversity damage, 82.47%; damage to agriculture, which would be crops, pasture, grazing and fencing, 81.02%; road traffic accidents, and I know a Deputy had experiences of that, 80.1%; damage to high-value nature conservation sites; damage to farm infrastructure; forestry damage; impaired deer welfare; and threat to farm animal health and welfare. All of these were over two thirds, or 66%. A two thirds majority in anything is very relevant and a public vote of over 66% means action is required. Everything over 66% is very much in the realm. The lowest impact was damage to gardens, which was 35.52%. Such damage is relevant to those involved but it is not something on which we will take Government action.

The other nature question that came out of that report was what do we do next or how can we manage this matter. There has been lots of discussion on deer management. We have looked abroad and at home and the general means of deer management is to reduce the population by culling, which is basically shooting. We have looked at previous options, such as contraception and other methods, but with deer being a wild animal such strategies are very hard to implement. A strategy might be noble and something that should be done but it just cannot be done with a wild animal. The Department of Agriculture, Food and the Marine can do things with badgers but badgers are a small animal and can be found in sets. Unfortunately, the same strategies cannot be applied to the deer population as a deer is a wild animal.

In terms of solutions, we asked the following questions. What is the importance of the following options in addressing the impacts? The main solutions are: deer culling 86%; supports for landowners or land managers to control deer 78.%, which also relates to culling; a commercially successful wild venison market 69%; increased access to education and training for hunters 69%; and contracting hunters 68.25%. It all relates to the culling of deer as a means of reducing the deer population. What you are not trying to do is roll out an extermination programme. It is important to get some kind of equilibrium into the scenario. As Chairman of the group, I engaged with all the stakeholders that were involved so the foresters, farmers, the farming organisations, the deer hunting organisations, the ecologists, the Departments and Coillte.

For the information of this committee, I will outline the members of the Irish deer management strategy group. There were seven members starting off. The three people from the Department of Agriculture, Food and the Marine were: Dr. Damien Barrett, who is here; Mr. David Quinn; and Mr. Seppi Höna. We had three people from the NPWS who were: Ms Claire Crowley; Mr. Ferdia Marnell; and Mr. Wesley Atkinson. The last member was Mr. Ken Sweeney from Coillte. I thought it was very important that the main State forestry body would be involved and Coillte is the major landowner. I will meet members of the senior management of Coillte next week. We have had an interdepartmental process and we have tried to bring every aspect of the thing into it.

I met all the stakeholders in the spring of last year. We had a full stakeholder meeting at the end of April where the focus was to present to the stakeholders the outcome from the public consultation and outline the next steps. After that meeting we set up five subcommittees and I know that it was asked in the Dáil what five subcommittees could do to solve the deer scenario. I put it to the stakeholders at the meeting that what we wanted to discover was what was going to solve the problem. I said we were looking for solutions and we would break them down into five areas. I said to the stakeholders that it would be their solutions to the problem and that the people who know the scenario must come forward with solutions.

We set up five subcommittees and the aim was to have ten people involved on each committee. We received 120 applicants for the five subcommittees, so we had to cull the number. Some organisations had people seeking to participate in two subcommittees rather than five subcommittees. We had to arrange it, so that we had appropriate people in appropriate places. We set up five subcommittees which are: venison; collaboration, which is very important for the group; legislation; training and education; and solutions for land management.

I wish to make one point which I neglected to make earlier. At the start of the process and before we did the public consultation, we looked at the report produced by the Wicklow Uplands Council. The council did some very good work on deer management units and case studies between 2018 and 2022. The council published its report in 2022. A lot of the groundwork had been done as to how these scenarios work, which I will discuss in a minute, and I put that to the five subcommittees. I did not chair any of the subcommittees.

The five chairmen are as follows: Mr. David Quinn, Department of Agriculture, Food and the Marine, chaired the venison subcommittee; Mr. Ken Sweeney, Coillte, chaired the collaboration subcommittee; Mr. Padraig Comerford, National Parks and Wildlife Service, chaired the legislation subcommittee; Mr. John Casey, Teagasc, chaired the training and education subcommittee; and Mr. Seppi Höna, Department of Agriculture, Food and the Marine, chaired the solutions for land management subcommittee.

We set up clear terms of reference for the five subcommittees. They had their own area on which to work If there were any overarching issues that people wanted to raise as part of their subgroup, and if they had not been a member of the other subgroup they could raise the issue with the subgroup as well, all issues would be fed into the scenario when drafting conclusions afterwards.

As regards a timeline, I gave the subcommittees a tight timeframe of two months in which to hold meetings. I did that because I feel that if things go on over a longer period, then meetings would only be a talking shop. Each subcommittee had a clear scenario of having output over a couple of months. Some subcommittees had two meetings while others had four meetings. The meetings were finished by 20 July of last year and we were fit to prepare proposals for the Minister by the end of August. We were keen that we had to look for funding for this process as the budgetary process was on as well. Funding was very important from our perspective.

What came out of the process? There was a lot of commonality between the groups so now we have 15 recommendations which have been put forward in the report. The group's report is quite comprehensive from the point of view that it gives a background and reason for deer culling, and the background to the biodiversity.

There are a number of main actions which are either short term or medium term. The most important short-term action is the appointment of a programme manager to set up deer management units with local co-ordinators. The issue with deer management in Ireland is that it has been everybody's responsibility and none so we need somebody for whom it is their sole responsibility.

As an initial phase we must establish a number of deer management units in local areas, particularly in the hotspot areas around the country to get the scheme up and running. We hope to do that in the next eight or nine months. We will engage on that immediately in the new year and we have meetings set up to go about that.

The next short-term action is for the programme manager, in conjunction with deer management strategy group, to develop an implementation plan. We are building so there will be further phases in this plan. We will start with the programme manager and look at areas around marketing venison, and assess whether supports are needed in areas for taking out younger animals. All that kind of stuff needs to be bottomed out and a budget attached. We must quantify things and put things together in a proper submission.

However, we cannot do it until we have somebody on the ground to do the assessments on that.

I mentioned setting up local deer management units. Revisions in the legislation and statutory instruments need to be done as well. There are a few of those around. The one in the Department of agriculture that needs to be addressed relates to how many deer a person can sell to a restaurant. In Ireland, a person can only sell three deer per annum to any one establishment. In the UK, the figure is 3,000, so that is quite a disparity. It is an issue that needs to be addressed and we have been working on it. There are anomalies that can cause problems in the system.

Another issue is in respect of the open seasons order and the term in which a person can shoot deer. For females, the open season currently runs from 1 November to the end of February. We are hoping to extend it and bring it into line with Northern Ireland, which would be from 1 August for stags and from 1 November to the end of March for females. We are looking to get that and I have been dealing with it. It is the area of the National Parks and Wildlife Service and is also a statutory instrument. It can be dealt with and we are hoping to progress it through the system over the next number of months.

Other changes to the Wildlife Act are needed with regard to how deer management units would work. At the moment, a landowner applies for a section 42 licence for out-of-season hunting. We hope the deer management unit could do this in order that things could be done as a block or body and there would be a consistent approach taken across a group of people rather than have individuals working together. A group approach will need legislation. The Wildlife Act is being reconstituted, which could take 18 to 24 months to complete. This provision needs to be included in it and that will happen in the next 18 to 24 months. Those are the kinds of things that need to be progressed.

On investigating supportive incentives, I spoke about that with the likes of venison. There are things we need to do very soon, including revising the statutory instrument process in section 42 of the Wildlife Act. In the medium term, a few things related need to be done to facilitate deer hunting within forestry and related to how forestry is set up. On mainland Europe, forestry is set up with deer lawns, that is, areas within forestry where you can shoot deer. I told the lads earlier that I travelled by bus from Frankfurt to Munich two weeks ago, which is a long journey. I counted 165 high seats for shooting deer on the trip that I could see from the bus. That is the kind of infrastructure in place in Europe for taking out wildlife on an ongoing basis. We do not have that infrastructure here. We need to put in an infrastructure. This is an ongoing process. We need a structure around it and a means for collating the data to have the statistics to make sure that what is set out to happen is actually happening. I think this can happen if the right funding is put behind it, there is a will to do it and we go about it. To be fair, we have cross-departmental collaboration between all the bodies. If we can keep the momentum going and get funding, I am confident we can make progress. I am appealing to the committee to put its might behind this to get it done. It is an important process.

The next point is to have phased certification for hunters over the next three to five years. This is to make sure all hunters have done the required training and have updated the training.

I refer to the integration of a deer management module in agriculture, forestry, land management and environmental training courses. That is just so people know about it and what is involved.

Another issue is setting up a deer management agency, which will take time. We had interactions with the likes of NatureScot in Scotland, which has a strong agency. It has 18 to 20 people whose sole job, seven days a week, is deer management in Scotland. There are quite a lot of hunters there. It is a bigger place and there are more deer, so it is a different scenario. However, it gives us a good template for what can be done. The targets they put in place for deer densities are a fraction of what we have in Ireland. In other words, we have a long way to go to get to anywhere near where they have been for a long time.

The whole deer piece is a big project. We are at the start. I am not promising huge progress in eight or nine months but if we can get a start made, we can build progress over a period of time.

Regarding the main impacts from the committee's point of view, I think the main impact in forestry is underestimated. New forestry has been severely impacted by deer damage, particularly native woodland. It is a huge issue in forestry. Coillte is definitely looking at it; it is on its radar. We have the issue of biodiversity, which is important. From the point of view of climate targets, forestry is a huge issue. TB has been well quantified. In County Wicklow, we have data for TB going back years, although it is not as well quantified in the rest of the country. It shows a clear correlation. I was in Wicklow 14 months ago at a large farmer meeting with the Irish Farmers Association. Dr. Barrett led it on the Department's side. I got a clear feeling of disquiet among farmers and the real damage that has been done where the densities are high. It is a broad spectrum of impacts across the country.

Deer cannot really be counted effectively. You rely on impact assessments, which need to be ramped up, be they road traffic accidents, biodiversity damage in forestry or TB impact, wherever they are in an area. The areas with the high impacts should be addressed first with accelerated management programmes in those areas. There are a number of hot-spot areas that need to be addressed, such as Wicklow, places in south Tipperary, parts of Kerry, south Galway and Donegal. The impacts will be the signpost towards this.

I have spoken at length but it gives a round-up of where we are.

The committee was anxious to get an update. It is long overdue. I know TB is only one part of the deer problem. Mr. Cashman pre-empted a question I was going to ask about his census of deer. He is saying he cannot get a handle of how many deer there are.

Mr. Teddy Cashman

That is correct.

Is the IDMSG setting a target for how many deer it would want to take out in any given season if the dates of the hunting season were extended?

Mr. Teddy Cashman

It comes down to local deer management units, which would set targets in their own areas. It is about co-ordination and collaboration. Let us say an area of 10 square miles is a local unit. You bring in a number of hunters as your dedicated hunters for that area. You bring in the farmers and, let us say, foresters are involved. Everybody meets and there is collaboration. You get a general view as to what the major impacts in that area are and what they see. From the start, we will need funding to figure out what success is and what impacts to look at.

I will give an example that I have given a number of times to give a slight flavour of how that might work. We were in Baronscourt Estate – Lord Hamilton’s place – during the summer to get a feel for where measurement was being done and for how this works. On that estate, there are about 2,000 ha – I cannot remember the exact size. They have been trying to count deer there for a number of years and have been doing it to some success, but the accuracy is plus or minus 30%. That is as good as we will get. They reckon they have about 750 deer and they are shooting 250 of those every year. They figure they have a density of about 21 deer per square kilometre on that estate. They are also doing impact assessments on 25 sites across the whole area they have from the point of view of biodiversity and regeneration. At 21 deer per square kilometre, the deer are still impacting very adversely on the biodiversity. They feel they need to get down to 10 deer per square kilometre, which is the level that Scotland believes is needed for the regeneration and forestry. It is clear that in many parts of Ireland, particularly in parts of Wicklow, there could be in excess of 40 deer per square kilometre. This figure is anecdotal, so I will not say it is perfect.

It is a multiple of ten in any case.

Mr. Teddy Cashman

Yes, it is a multiple of that. You have to look at the impacts on an area and base your targets on that. I cannot give the Cathaoirleach an exact figure but it will be based on the local impacts on an area and a focused job being done in a focused area. The biggest issue from the point of view of tackling and managing deer is the consistency of approach, for example, the same guy coming in every year doing the same job. We know what he is doing and the farmers involved know what deer are shot on their ground. There is communication going on.

There was quite a good case study done in south Galway between a number of farmers, a local co-ordinator and the local IFA. The National Association of Regional Game Councils, NARGC, brought in hunters. They have been doing something like a deer management unit there for the past two years because there was quite a large impact by deer. They have had a consistent approach for, I think, two years now and they have brought down the numbers. They have been meeting and having discussions on it and everybody knows what is going on. That is why the collaboration among groups is so important.

It is a big job. Training and education is nearly as important as anything. It is important that when you bring people in at the start, everybody knows what is happening, why it is happening, who will do it, who will pay for what and how we will go about it. It will have to be replicated across the country if it is going to work.

I thank the witnesses for attending.

On the back of Mr. Cashman's report, and given the time of year, it is important to assure anyone listening that Rudolph and his colleagues are in no danger of being shot. That is an important message to send because there may be young ears having to listen to us because daddy or mammy want to listen to us.

Deer have appeared near my home when they were never there previously. There might not be that many of them. We cannot count the national herd. I do not know where they are coming from or how many there are, but they are appearing on the roads when they were never there previously. I presume that an organised cull, should one happen, will concentrate on areas such as Wicklow where deer are prevalent. They are now prevalent in my area but were never there previously. It is a major issue. If we cannot count them, the witnesses will hardly be able to answer my next question. Is there any proof as to the rate of TB? Are deer spreading TB? Is it prevalent with them? Are they just carriers? Is it the big issue people are making it out to be? Is there any scientific proof for that?

I have a couple of questions for the Department on matters we have discussed previously. One matter was mentioned on the previous occasion the Department's representatives were before the committee but I see no mention of it in the report. The old adage is that prevention is better than cure. The only mention of vaccination in Mr. O'Mahony's opening statement was vaccination of badgers. Has that been proved to work? Are vaccinated badgers retested? Has there been instances where vaccinated badgers have later been proved to have TB?

Vaccination is the future. That is science. It is the way we are going. Look at the pandemic. Vaccination got us out of the hole in the end. Has there been any development of a vaccination for bovines? Representatives of the Irish Cattle Breeding Federation, ICBF, were before the committee this morning and the witnessers know what we were talking about. In the mix and part of the index are the TB-resistant traits they are beginning to see. They said it is not going to be the solution to the problem, and I cannot see how it would be. Calves may come from a bull with a good TB resistance rate but if they live in a field beside a wood that is full of deer and badgers, they have a better chance of getting TB than their brothers and sisters in a high field somewhere far away. I do not know how to make the correlation or do the science. However, the ICBF representatives seemed to think there are TB resistant traits. Will science bring us to a situation of prevention, whether through vaccination or breeding? We will be working on a cure for a very long time because we have already been at it for a long time. We are only holding our own. We are peddling hard to stand still. I know the numbers of cattle have gone up so the percentage of those infected with TB in a larger herd will be a bigger figure. There might even be a smaller percentage but that can mean a larger number of infected animals if the herd is bigger. There are always going to be deer, if deer are the problem. There are always going to be badgers. With the best will in the world, a cull is only going to maintain a steady number of deer. We are always going to have deer. Unless we can start vaccinating deer as well, we are always going to have TB. It will be an issue while we are depending on testing, identification and removal of the reactors and unless we can come up with a prevention. I would like to know where the science is at with respect to a potential vaccination. Is the vaccination of badgers the gauge to be looking at? Is it working in badgers? If a vaccination is working in badgers, why is there not a vaccination that would work in bovines?

Dr. Damien Barrett

I thank the Senator. He asked about the level of TB in deer. We have conclusive evidence that deer are involved in the epidemiology of TB in County Wicklow. In one particular study, we found that up to 16% of deer that were tested post mortem were positive for TB. In the same study, we saw that between 30% and 35% of badgers from the same area were found to be positive for TB. Samples are collected from heads and plucks from hunted deer that have been presented to the regional veterinary laboratories for examination. The TB level to date has been of the order of approximately 2%. I accept, however, that the absence of evidence does not necessarily mean evidence of absence and we are encouraging farmers and hunters if they have any suspicions to present the heads and plucks from hunted deer.

The particular issue in County Wicklow, as Mr. Cashman alluded to, is the density of the population. That is an issue across the board when it comes to all species of TB. It is about the density of the population. There is a particularly high density - more than 40 per sq. km, as Mr. Cashman said - in County Wicklow. It is an issue of population density, and that goes for all species.

The Senator also asked whether the vaccination of badgers is effective. We have carried a non-inferiority trial, which has demonstrated that the vaccination is no worse than culling in the control of TB in the population. It has a similar effect in terms of the risk to cattle. That was a controlled trial in a controlled set of circumstances. When the vaccine is applied, it works. The difficulty is with the logistics of getting it out into a large population. The other thing to bear in mind is that if you are vaccinating, you are not culling. It comes back to the point that we may have a certain level of increase in the population. There are issues in respect of the logistics to get good coverage. Studies have shown that we need to vaccinate approximately half the badger population to get the level of protection we require in the population.

The Senator also asked about a vaccine for bovines. The difficulty with the current vaccine is that if we give the vaccine to cattle as it stands, they would fail a tuberculin test, which would have enormous implications for exports. That is currently the case. Our colleagues in the UK are developing what is known as a diva vaccine or a marker vaccine, through which it would be possible to differentiate an immune reaction that came about as a result of vaccination from an infection. They have completed the safety trial. They have demonstrated that this vaccine does no harm. They are a bit away from getting the vaccine to the market and getting market authorisations and anything like that.

The other difficulty will arise in respect of the World Organisation for Animal Health and the whole issue of certification and getting acceptance for a product to be certified as TB-free if it has been vaccinated. There could be a lot of politics involved in that.

The Senator also asked about genetics. There is no doubt but that genetics on their own are not a silver bullet, but they are a part of our arsenal to deal with this. Animals with a high susceptibility to TB on the basis of the genetic tests have been shown to be almost one and a half times as susceptible as their comrades with a high resistance. If there is enough of an infectious dose, they will succumb. However, animals with a higher resistance have a greater ability to resist becoming infected.

I know Dr. Barrett has said it was only conducted on a trial basis, but even from the evidence of the badger vaccine, what is the longevity? For us, in response to the pandemic, we have to get a booster shot every year. If an animal is vaccinated once, is that all that is required for life, as is the case for the vaccinations we all received as kids? If the vaccine was up and running and we were using it, would it have to be administered annually?

Dr. Damien Barrett

The Senator has nailed the point with that question. The vaccine they get is the same vaccine we got as kids, so it is lifelong. It is certainly lifelong for the badgers.

It is on trial in the UK at the moment.

Dr. Damien Barrett

The cattle vaccine is on trial, yes.

That is the one that will not show up in the test of the carcase-----

Dr. Damien Barrett

The vaccine that you can differentiate between infection and vaccination, yes. That is on track.

If and when it is proven to be a runner, would the Department pursue or look at it? Given it has got over all the hurdles Dr. Barrett identified, animal rights, WOAH and all that, has the Department an open mind on vaccination or is it actively pursuing it?

Dr. Damien Barrett

We have very much an open mind to this. If and when it becomes available, we certainly will explore this. It is something we would be interested in pursuing.

How long, given the trials taking place in England, will it be before we could have a definitive conversation about the possibility?

Dr. Damien Barrett

We met some of our UK colleagues a couple of weeks ago and our understanding from that is that this is at least ten years away from the market.

That says a lot.

In the different groups the IDMSG set up, has anyone looked at putting in proper fencing between farms and forestry that would stall deer eating most of the grass and maybe spreading infection? Mr. Cashman mentioned a few places. In Newbridge, County Galway, there are roads you cannot travel on at night with the herds of them going around the place. I am fairly familiar with the Wildlife Act but going by what has been said, it would be two years, at a push, before we would see good results. Some of the people we would be looking to change bits of legislation with might not be pushing it as fast as we would want, with some of the agendas being pushed in here. I am concerned legislation would be holding it up. Does Mr. Cashman fear that is a roadblock? If communities got together and did something, is there a way of taking them out, shooting them or blasting them? It is ferocious.

There was a story a few weeks or a month ago on thejournal.ie about regionalisation. Has that gone to bed? It was that you would not be able to sell cattle if you were in a certain area. Has that gone away?

Has vaccination worked with badgers? We are hearing mixed stories, with some saying it did not appear to. It would be nice to know if it has or not. If it is working, is there much of it going on at the moment? I am hearing there is not much vaccination of badgers going on.

The big problem for the Department in any TB breakdown – and it is no reflection on the witnesses - is it does not have enough boots on the ground or budget for that. When there is a breakdown of TB in an area, even for snaring badgers and so on, there is one person who will come out but the poor divils would want to make 40 out of themselves to be in 40 different places. The Department needs more resources if it is to tackle this head-on.

Addressing Mr. O'Mahony, I have been preparing for this morning by looking at the figures. On TB resistance, am I correct in saying that if you were to say that Ireland was free of TB, the Department's figures are for 300 herds or 15,000 cattle? Is that the guide it looks at as being TB-free? That is the information I have been given. I have spoken to vets, some in England and some in Ireland, who have done a lot of research. The witnesses probably know some of them. They say most cattle killed do not have TB going through the lungs and blood. Many show the lumps but when they go into the factory it is not full-blown TB. You could be doing everything right, putting every deer everywhere, and eliminating that side of it, because that is a problem. We know the badgers also are a problem but you could have cattle in a shed all the time and if they come under stress, especially on the dairy side, TB can start in them. Is that right or wrong? The information I have is there is no vaccine that will get rid of TB, but are there MRNAs that might stall it, like the Covid one? The make-up of a vaccine for a person and that for an animal, bullock or cow is totally different. As for farmers, is the pedigree side of it solved? You could have a fairly valuable animal and there was only a certain figure. Has agreement been reached on that for farmers? Manpower is a big problem for the Department. More funding needs to be put into tackling and resolving that as quickly as possible because it is a hellish problem for farmers.

My final point is for Conor or Damien. People say we will eradicate TB. Realistically, that will never happen.

Mr. Teddy Cashman

To respond to some of Deputy Fitzmaurice's comments, the fencing one was discussed but did not come up as a main recommendation because it is not seen as entirely effective over time. It is a short-term fix and not too many people involved felt it would solve the thing. The forestry section in the Department has approved fencing grants of €18 million this year for new forestry. Overall, fencing does not appear to be totally effective and I do not feel it is-----

The forestry section will tell you that, because its forests are bringing those deer onto our land.

Mr. Teddy Cashman

Fair enough. The point I make is that deer are wild animals. People do not like to hear this but what I am told is the deer belong to wherever they are at the time. They are your responsibility if they are on your land. If they are on Coillte’s land, they are Coillte’s responsibility, or parks and wildlife or whatever the case may be.

Deputy Fitzmaurice mentioned the two years and is right that ramping up a programme will take time.

There is no doubt about that.

Some 55,000 deer are shot in Ireland annually at the moment, based on the figures we have available to us. It has gone up from approximately 36,000. These are the returns the registered hunters send back when they apply for their licences the following year. It is a somewhat arbitrary figure but it is the figure we have.

Mr. Cashman mentioned the meat and restaurants, and the way we might be able to help in that.

Mr. Teddy Cashman

At the moment, if a deer hunter wants to sell meat into a restaurant the maximum he or she can sell is three deer per annum.

Mr. Teddy Cashman

Three. In the UK it is 3,000.

What is the logic behind that?

Mr. Teddy Cashman

I am researching it at the moment.

Does this come under the Wildlife Act?

Mr. Teddy Cashman

It is under an Act in the Department of agriculture with a statutory instrument.

I imagine that a statutory instrument can be struck out with the stroke of a Biro.

Mr. Teddy Cashman

It is something we need to progress. I will put it that way. I cannot say any more about that, this is as much as I know. It is an issue and was raised in this process and I am bringing it further. I am learning about it.

I will make a point on the deer issue, which I believe is important. As I have said, this is a cross-departmental process. Parts of the National Parks and Wildlife Service are involved, as is Coillte. I am engaging with them at the highest level on an ongoing basis and they are very much keen to increase their engagement with deer management on their lands. They have been suffering for the last few years as well in the context of lack of boots on the ground. In Wicklow, they are piloting a project this year of bringing in contract hunters in parts of Wicklow after Christmas this year. They are hoping to roll that out around the country. They have not done it yet but they are hoping to do so and are telling me about it. I am meeting Coillte next week and I will be looking for them to do something similar in that scenario. If the main bodies can ramp up on one side that would be a quick fix and fairly quickly.

Does the Department ever tie in with gun clubs? I remember one time ago on Sundays there would be a fox hunt. It would be on foot. They would have dogs, drive them out and get them. Is any of that done?

Mr. Teddy Cashman

The gun clubs have been central in developing the thoughts and process around this. The National Association of Regional Game Councils, NARGC, is the association of national gun clubs. It has been very involved in the process. I spoke to them out in south Galway. They are involved on all the different committees we had, as were all the other country organisations such as the Irish Deer Commission, the Irish Deer Society, the Deer Alliance Ireland, and the Wild Deer Association of Ireland. Quite a few of them out there are involved with deer management.

There is a point to be made around the deer issue and registered hunters. There are 6,000 registered hunters who have their hunting licence as of 2023. It is registered hunters who are able to do the proper deer stalking. It is about tying up with the local people and the proper registered deer hunters to get the job done. If a deer management unit is set up and one gets goodwill going, then one can get a lot done in a short space of time without a whole lot of money to begin with. To get it to the next phase where there is a really large number to be taken out is when we would probably need to put incentives in place. One of the logjams in that is dealing with the venison coming out of this if we start to accelerate the cull. We will need to address that immediately after Christmas as to what options are needed around that.

What are the options?

Mr. Teddy Cashman

All options will be have to be investigated for the large numbers out there.

On the legislation, I do not see the legislation as a major impediment. It will be a help but it is not going to be the solution. It is another plank but it is not going to be the big plank. The big plank is getting a co-ordinator out there, getting up and running and getting people involved. We have people in the context that all stakeholders have been involved in the process so far and we need to get people involved on the ground as well. If we keep the momentum going we can do that.

Mr. Conor O'Mahony

I will ask Dr. Griffin to address the regionalisation. There are also a number of questions that Dr. Barrett might cover, and then I will finish up with the question on pedigree ceilings.

Dr. John Griffin

I thank the committee for the opportunity to speak. I will start with the last question on whether eradication is possible or not. Certainly from a scientific point of view there is absolutely no reason why we cannot eradicate tuberculosis in cattle. Tuberculosis has been eradicated in many countries. In the European Union the vast majority of countries are free. The actual legal requirement is 0.2% of the herds. As Ireland has approximately 200,000 herds, we need to get less than 200 to be declared free. Most of the European countries are at that stage so certainly there is no reason from a scientific point of view.

What are they doing differently?

Dr. John Griffin

Some of them eradicated the disease a number of years ago but basically they are using the tools that we are using. One difference is that they did not have a wildlife problem with badgers and other wildlife such as we have. The countries that are finding it difficult now to eradicate, like Spain, also have identified the wildlife problem, in terms of boar and deer and so forth. That is certainly one of the issues. Most countries have eradicated it with the tools available, however. Even though it has a wildlife problem, Spain is certainly a good bit lower than us in terms of the levels.

What is the definition of eradication? Am I right in saying that it is not zero? It is 0.2%.

Dr. John Griffin

Yes. We need to be really careful in how we define eradication. It is a really good question because there is legal eradication, which means below a certain level in the herd population at 0.2% of the population. That is not biological eradication. If there is still TB in the population, it can still rise if the foot is taken off the pedal. We are really looking for biological eradication where we actually completely get rid of the disease. That is ultimately the goal but it is important to distinguish between those two points.

On the other point about the regionalisation, I will briefly mention the role of my group. I am the head of the scientific working group in the TB forum. Basically we get questions from the TB forum itself or from the Department of agriculture to look at particular issues from a scientific point of view. We look at those, review all the science and we provide information. It is important to say that we are not advocating regionalisation or anything else that we are asked to look at. We just provide the information and then it is for the Department or for the forum to decide what to do with it. With regionalisation the idea is that one take a particular part of the country initially, works that and then moves on to other parts. This is how the eradication programme started in Ireland. In 1954 Sligo and Clare were the first counties identified for TB eradication and then it gradually spread to the western counties and then to the rest of the country to the point where in 1965, we declared ourselves legally free of tuberculosis. So a regional approach was used. If we look at other countries, most countries do use a regional approach in terms of-----

My understanding was that cattle could only be sold locally. Was that proposed?

Dr. John Griffin

Not exactly. If a regional approach is to be used two things must be done. First, you must completely rid the region of TB. Second, you must then stop infection from coming into that region because there is no point in getting rid of infection and then have loads of infection coming back. Those two requirements must be met. To meet the first requirement, we are talking about high-quality testing and so on to get rid of the disease. To prevent it from coming back in, the two main sources of TB for herds must be prevented. These are wildlife and other cattle. As Mr. Cashman has said, there is a good wildlife programme in place for deer or badgers but the main constraint really is other cattle. It is the view of our working group that the main method of transmission of TB in Ireland is transmission between cattle. In our study on the regionalisation we found there was quite a lot of movement of cattle from high-risk herds to low-risk herds. If there is to be a successful eradication programme then we need to deal with that. By high-risk herd I mean a herd that may recently have had an outbreak of tuberculosis and has just gone free. There is loads of evidence to show that those herds can still have some infected animals because the test is not 100%. There can still be some infected animals in those herds.

Is the blood test 100%?

Dr. John Griffin

No. The blood test is not 100%. If they are done correctly, both the blood test and the skin test will identify about 80%. The blood test might be slightly better but the problem with the blood test is that it will pick up a lot of false positive animals. There will be quite a number of false positive animals with the blood test. That is why it cannot be used as a screening test. It is because we get too many false positives.

Dr. Damien Barrett

I will take the question on vaccination. Deputy Fitzmaurice asked how much vaccination is going on. I will also mention culling. This year to date we have captured more than 8,000 badgers for vaccination. This is an increase from approximately 1,900 in 2019. Since 2019, apart from 2020 when there was a reduction because of Covid, we have been culling between 5,000 and 6,000 badgers in high instance areas. If there is a high risk breakdown in a particular region, badgers are culled and vaccination goes on in parallel.

Deputy Fitzmaurice made a point about manpower. We have our own technical agricultural officers who supervise subcontractors from the farm relief service who do the work. The number of people being supervised by a technical agricultural officer has increased from two to three. There is an increase in the manpower. The committee may be aware that there have been issues with technical agricultural officer vacancies. Much good work has been done this year in addressing these vacancies. It is not completely fixed yet but things are a lot better than they were this time last year.

It is worth pointing out that no matter how many people the Department of agriculture puts on the ground it is probably an impossible task to fully identify all badger setts. We rely on the farming community to tell us about the location of setts. Next year we hope all identified setts will be on the basic income support scheme maps when they are issued next year so that if people are not aware of setts on their land they will become aware of them. We want to know where they are.

In spite of all this, and we will never have all of the manpower we need, we are asking farmers to fence off setts. It is not about keeping badgers in setts; it is about preventing close contact. The area immediately outside a sett where the badgers are defecating and urinating is high-risk material. If we could stop cattle from grazing that grass that is contaminated, it would go a long way. We are also asking farmers to badger-proof their farmyards. Feeds such as maize and beet are particularly palatable to badgers. They are particularly fond of it. People have to have these feeds but we ask that they could at least keep them in a way that the badgers cannot access them.

I ask the Deputy to clarify his question on TB resistance.

I hear that certain cattle would not have to be near a badger or deer because they could be in a shed and when they get stressed they show up with TB. Is this correct?

Dr. Damien Barrett

They have to get it from somewhere. Cattle to cattle transmission is something we are probably not dealing with enough. The spread within species is far greater than the spread between species. The spread between badgers is greater then the spread from badgers to cattle and the spread between cattle is greater than the spread between badgers and cattle. Animals do not get it out of nowhere. There may well be animals that are latently infected or anergic and they may not react to the test. A feature of the disease is that certain animals do not react. It is long-standing animals that probably pose the greatest risk as they may not necessarily react. There has to be a source somewhere.

What about a vaccine?

There is a vote in the Dáil. The Leas-Chathaoirleach will take the Chair and we will return as soon as the vote is over.

Senator Lombard took the chair.

Dr. Damien Barrett

Is this about a vaccine for cattle?

Yes, earlier Dr. Barrett spoke about a vaccine for TB and it was mentioned that it would be dangerous. He said that given other countries we have to be careful how we go.

Dr. Damien Barrett

Yes.

Is there anything that would be foolproof? Is it about eliminating the outside problems and trying to eliminate TB in badgers, deer and other animals? Badger-proofing yards is very interesting. Farmers should know more about making a yard badger-proof so they cannot get in.

Dr. Damien Barrett

The issue with vaccination is about certification. There are politics and international politics involved. The Deputy may well be aware that from time to time animal health may be used as – I do not want to use the term "trade barrier" but the Deputy knows where I am going. Phytosanitary rules may be used to the advantage of certain countries. We need to get the support of the World Organisation for Animal Health to overcome this issue.

I thank Dr. Barrett.

Mr. Conor O'Mahony

The Deputy asked about pedigree ceilings. One of the subgroups of the TB forum is a financial group under the chairmanship of Gerry Kiely. It has looked at the funding and supports available under the TB programme. One of the issues we looked at was the ceiling for animals under the scheme. The previous ceiling for pedigree cows was €3,000. This has been increased to €5,000 for pedigree cows and in-calf heifers. This figure was arrived at by examining the valuations submitted in recent years. We are conscious there are some very high-value pedigree animals that were valued higher than the ceiling of €3,000 and were not being fully compensated. This ceiling has risen to €5,000 since 1 February. We had to update our IT systems and backdated payments will be issued to anyone who did not avail of it.

I thank Mr. O'Mahony.

I was thinking that while it would probably never happen I would not like to go on a road trip with Mr. Cashman if he was looking out the window the whole way to see where he could shoot from. I hope he was not going to the Christmas markets with his wife in Germany when he was looking out the window.

Mr. Teddy Cashman

No, it was a different trip.

That is all right.

On a more serious note, it is great to get the insight and I commend Mr. Cashman on the work he has done on the deer population. It is probably fair to say we are way out of step with the rest of Europe and certainly with our nearest and dearest neighbours. Has Bord Bia had any input into the venison market and the deer market? What is the volume and where should we pitch this? How many deer should be going into the market? Has this been considered or has anybody given this information? Our vested interest is to look after and protect farmers. Farmers want to sell beef. There is a certain irony if we are looking to sell venison as well. At the same time, there is a market. Does Mr. Cashman have any knowledge on how much imported venison is being sold in the country?

Mr. Teddy Cashman

I thank the Deputy. At the start of this process when we set up the subgroups, I was very keen that we would have Bord Bia involvement on the venison subcommittee in particular. We also had somebody from the Restaurants Association of Ireland, game dealers and hunters. We did not have farmers on the venison subcommittee because they were not relevant to that particular subcommittee. All of these issues were raised. Agriland.ie had an article in recent days on the recommendations made, including the statutory instrument I mentioned and establishing an international market for venison.

Currently, many of the game dealers buying venison from hunters in Ireland are exporting it directly to Scotland. It appears to be a developed market for venison and this is where the meat is going. I think there are many gaps in the venison scenario in Ireland. Bord Bia has done some work in this area, but not a lot. We will engage with it further when we have gone farther down along the road from the perspective of volumes.

This is something that concerns me a small bit in the sense of marketing and dealing with the venison. There is viable and non-viable venison. Many females and smaller animals will have to be culled to bring the numbers down because these are the animals that will bring down the population and not so much the stags. Stags seem very impressive visually but they are not very useful from the point of bringing down the size of the population. Regarding what was referred to earlier in the scenario, a certain proportion of this meat will have to go into the pet food trade or something like that. A portion of the meat will, however, be good-quality venison. We need more of an infrastructure around the country to deal with this type of meat, including larders for hunters and chillers they can bring the deer to and deer agencies can come to collect them from. Some of this kind of infrastructure exists now. It is not entirely absent around the country.

Mr. Cashman said there is a very good project in County Galway. I think that was the one he referenced. There is no upside here for farmers apart from the reduction in the deer population. There is no direct financial gain for farmers. Is there an opportunity to consider a scheme that would reward farmers for deer culled in their areas?

Mr. Teddy Cashman

It is an interesting question. There are two aspects to it. First, we are relying on the deer hunter to do the hunting. It can take up to 30 hours, between stalking and hunting, for a deerstalker to bring in an animal. This is the average for the number of deer they bring in. These 30 hours represent a long time, so there is a need to get a return for all those hours worked.

Typically, how much is a deer worth to the stalker?

Mr. Teddy Cashman

It is €2 per kilo. An average-sized deer might weigh 55 kg or 60 kg for a big one. The smaller ones then become uneconomical, so this is where the supports need to come in, at the lower end. There is not a lot of money involved really. Some very good deerstalkers could shoot quite a number of animals over the season and some might only shoot five or six.

It is not going to save farming anyway.

Mr. Teddy Cashman

No. I referred to the estate of Lord Hamilton earlier. If a deer is shot on farmland adjacent to that estate, the farmer is compensated for the weight of the deer got on his or her land. We have not got that far here yet. Many farmers just want to get the deer gone, and the hunter will need to be compensated. It is a complex area to try to figure out. There are many trained deer hunters. Another point to consider here is the reason we have the training for deer hunters. There are a few aspects to it. One is that they have to be able to stalk the deer, while the second is that they must be able to humanely shoot the deer. That is very important. In other words, they need to have the right training. Three different agencies are providing training for deer hunters in Ireland. Another aspect of this is that the hunters need to be able to disembowel the deer on site to ensure the carcases can be hung within a certain time to be bled and make the meat suitable for human consumption. There are several aspects that need to be considered here.

Reference was made to Lord Hamilton again. I imagine much of the activity on his estate is hunting tourism. Professional hunters would be accompanying people.

Mr. Teddy Cashman

It was, but it is not now.

It is not anymore.

Mr. Teddy Cashman

It is not because the professional hunters were targeting the stags and this was not bringing down the deer population. The estate now has its own stalkers employed directly. The deer hunting has been cut out. A large financial gain resulted from the deer hunting, but when the loss to the forestry business was weighed against the financial gain from the deer hunting, the outcome did not match. This has been the point we have been making here. Coillte sells many licences for deer hunting as well and it is also considering this balance. This is one of the conversations we will be having next week with the company. I will be learning more about this and we will be pushing the envelope as much as we can. To be fair to Coillte, it is very much on board.

On the venison question, we have done the overarching work as the start of the study. What we are looking at is the helicopter view, but we need to get into the details. We know what some of the details need to be but we need to start enacting them. As I said, we will be looking for everybody's support to do so because I think this is the right direction to go.

I have a question for Dr. Barrett on badgers. Roughly how much does each vaccination cost per badger?

Dr. Damien Barrett

Roughly speaking, it costs approximately €300 per badger.

It is costing €300 per badger.

Dr. Damien Barrett

Yes. That covers the various parties involved.

It is not just for the vaccine but for everything involved. It is still €300 per badger though.

Dr. Damien Barrett

Yes.

What is the life expectancy of a badger?

Dr. Damien Barrett

I think it is four or five years.

At the moment, we are vaccinating about a quarter of the population. Is that where we are at, typically?

Dr. Damien Barrett

Yes. We are at about 7,000 to 8,000 badgers being vaccinated annually. I would say it is less than a quarter of the population. It is probably between 15% and 20%.

If the lifespan of a badger is four to five years, is it the case that there is never going to be an effective vaccination programme because we are never going to catch up with them?

Dr. Damien Barrett

All these badgers are going to have offspring and they will need-----

It is going to weigh in with each generation.

Dr. Damien Barrett

Immunity is not transferred from the mother to the young badgers. The young need to be vaccinated in their own right.

That is what I mean. We are going to vaccinate badgers this year but the reality is that within four to five years, those animals will be gone.

Dr. Damien Barrett

I think it is fair to say for the foreseeable future, yes.

Okay. We had the ICBF before the committee earlier. There is a bit of disquiet concerning the emphasis it has in its new indexes in respect of TB. Is it possible to breed TB out of cattle?

Dr. Damien Barrett

Not on its own; breeding on its own will not eliminate this problem. As I said to the Deputy earlier, if this was easy, there would be one single solution.

Yes. It would be sorted.

Dr. Damien Barrett

This is a game of doing a lot of small things right rather than one single thing. Sceptical might be too strong a word to describe how I felt initially, but I started looking at the evidence for this, particularly on the dairy side as opposed to the beef side. Before TB was incorporated into the EBI, a large number of the top EBI bulls, when we looked back at their TB figures in retrospect, were very bad. This meant their progeny would be highly susceptible to TB. In an industry like this where one or two popular bulls, or a small number of popular bulls, could have a large number of progeny, this has an impact. It was really highlighted to me when I saw that quite a proportion of the top 20 EBI bulls did not have great TB resistance figures. The situation with beef is slightly different. I certainly think, however, that genetics has a contribution to make, but it is one of several things we need to address.

On a scale from one to ten, where would Dr. Barrett say the progeny errors rank? Obviously, we have aspects to consider such as the deer, the badgers, better herd management and all those things. About six or seven key points were mentioned in this regard. If Dr. Barrett were to rank these items from one to ten, how important would the progeny factor be?

Dr. Damien Barrett

The Deputy is referring to the resistance.

Dr. Damien Barrett

The trouble with TB is the context. The context in which the question is being asked is very important. I do not think this aspect is a showstopper in any circumstances but it could have quite a contribution to make in a situation where we have many susceptible animals together in a particular set of circumstances, say, where animals are housed closely together and densely stocked. I could not give the Deputy a ranking of where this factor comes in terms of a score from one to ten because it is specific to the context.

Regarding where we are with TB, we have probably had a marginal increase in recent years. A case could be made that this is as good as it is ever going to be.

At the same time, we have huge sympathy for farmers who have their herds closed down. Is it not to the detriment of the dairy and beef industries to prioritise the genetics of TB over the genetics of better stock?

Dr. Damien Barrett

Deputy Flaherty is asking me some questions that are probably more for a geneticist than a vet. My understanding is that-----

I value the opinion of a vet more than a geneticist.

Dr. Damien Barrett

I do not think one necessarily rules out the other. If we are to bite a bullet, the bullet is cattle movement and cattle-to-cattle spread when high-risk animals move out of herds. If we increase the resistance of the population overall, that would be helpful. I am not in my comfort zone talking about genetics.

Well Dr. Barrett did very well. I thank him.

Deputy Jackie Cahill resumed the Chair.

I thank the witnesses for their opening statements and submissions. Many of the questions have been asked and answered. The eradication strategy has been well under way since 2021. The witness said several key actions are being implemented and are close to full implementation. Of those outlined on page three, will the witness provide more detail about those that are almost there and those that have a bit to go in implementation?

Mr. Conor O'Mahony

Is it page three of the briefing document or of the speech?

Apologies, page three of the opening statement.

Mr. Conor O'Mahony

Will the Deputy confirm that she is referring to the section about movement of cattle with undetected infection and residual infection spread across farm boundaries? I want to ensure we are talking about the same thing.

There is a list of about 12 factors, starting with "Preventing spread from herds with a high risk of recurrence".

Mr. Conor O'Mahony

I will provide a high-level overview and Dr. Barrett can come in on the more detailed questions. The first key action is preventing spread from herds with a high risk of recurrence. These herds have difficulty getting free from TB restriction. It is about using tools such as gamma interferon testing to flush out as much infection as you can and educating and informing herd owners of the steps they can take to reduce the risk of recurrence through biosecurity. This means that if they replace stock, it should be bought from lower-risk herds. Herd management and management of the disease will reduce the risk of future recurrence. The second key action is enhanced actions to clear infection from extended breakdown herds - they can run together. Much of this is based on data such as the profile of the herd, more regular testing in addition to gamma interferon and continuous programmes around those herds. The third key action is addressing the risk from inconclusive animals. Historically, if a farmer had an inconclusive result and the animal subsequently passed the test, that farmer could trade on the animal. That could potentially have passed on infection because the animal was inconclusive. A policy change in that area was that such an animal was restricted to that herd for life - it could not move on. We have also encouraged additional testing. When subject to a blood test, 60% of animals that tested inconclusive proved to be positive. It is about proving inconclusive animals are an additional risk and ensuring that they are taken off farms. The fourth key action is action plans from areas with increased localised TB levels. Certain parts of the country are hotspots with high levels. We call them HIT plans to increase testing and examine the causes in these areas. We focus resources on those particular areas to reduce TB as quickly as possible.

Are those action plans in place?

Mr. Conor O'Mahony

Yes, for several years. They can be at quite a local level, at sub-county level.

The fifth key action is aligning with changes in the EU animal health law TB regulations. As a result of the new animal health regulations, we implemented this for TB on a phased introduction this year. Phase 1 was introduced in February, in which all cows of any age and males over 36 months, if they move from one farm to another, must have been tested within the past six months and the herd from which they moved must also have been tested within the past six months. If they cannot satisfy that criterion, they have to have a 13-month pre- or post-movement test. It is additional testing of what we consider higher-risk animals, such as older breeding animals.

The sixth key action is reducing the risk posed by badgers. This has been done by increasing the resources of the wildlife unit. In 2019, we spent approximately €4 million on the wildlife programme. So far this year, that is up to approximately €7.4 million, I think. Dr. Barrett discussed resources. The farm relief services complement has gone up from 115 farm relief resources in 2018 to 156 currently. That demonstrates the additional resources we have put into the badger aspect of the wildlife programme. Mr. Cashman discussed the overall approach to deer, key action seven, so there is no point in going through that again.

The eighth key action is tailored, simplified communications between the Department and herd owners. A communications subgroup has been established through the TB forum. This contains farm organisation representatives and Department staff. TB, as everyone is aware, is a complex disease. It is about providing a simple and clear message to farmers about the actions they can take for badger control - there is the Stop, Stop, Tell programme. We launched the badger app on which there have been 1,400 notifications since 2021. We are giving farmers tools they can use themselves and we are simplifying quite a complex message in as simple and accurate a manner as possible. That is a good example of how we and farm organisations can collaborate. A lot of information is contained in the TB programme, which will be ongoing.

The ninth key action is clearer messaging of the risks of TB transmission and how to address them, which falls under communication. There are several videos on our YouTube channel and we have a dedicated website, bovinetb.ie. The videos cover everything from testing facilities, what to expect from a herd test, how to ensure an accurate herd test, badger control, badger setts and badger fencing. It is clear, simple messaging of the risks. Biosecurity advice is also delivered to farmers. Unfortunately, the first time many farmers address TB is when they have an outbreak and a restriction. The first time biosecurity advice is brought up is when a Department vet goes out to a restricted holding, takes the farmer through the biosecurity advice relevant to their breakdown based on the contributing factors in their breakdown, their setup, their holding, characteristics of the holding and the herd profile. They have all been implemented, to varying, degrees quite successfully.

Again, they are ongoing. As I said in the opening speech, we would like to go beyond that. Dr. Barrett has discussed cattle movement. Dr. Griffin has re-emphasised, in terms of regionalisation paper that clear, simple actions need to be continually done.

Dr. Damien Barrett

We are making a special effort with the herds that we call "relapse herds". These are herds that have broken down. We have a definition of three or more standard reactors that would indicate cattle-to-cattle transmission. This is how it is spread. It is probably confined to the animals. When there are three or more standard reactors, we are very worried that there will be onward cattle-to-cattle transmission. These herds can relapse. I refer to animals of a specific group, such as cows. If a cohort of cows was present at a breakdown previously, they are a special concern to us. We have a programme where we now follow those herds much more aggressively.

Another thing to which I would like to draw the Deputy's attention is that we are trying to involve people's private veterinary practitioners more in providing advice. There is a programme called the targeted animal advisory service for animal health, TASAH, which we do in conjunction with Animal Health Ireland. In this, we fund herd owners and private veterinary practitioners to go out and do a risk assessment and provide bio-security advice. Approximately 300 of those visits have been carried out. Almost 500 vets have been trained to do this. This is something we want to expand because we are cognisant that the herd owner's private vet is probably more familiar with the situation than a Department official would be. There is a valued relationship there that has taken place for quite some time. Things might be communicated better that way.

I think Mr. O'Mahony has covered everything else.

I call Senator Lombard.

I would like to welcome the witnesses and I thank them for their contributions. First, I would like to declare an interest. I have been up and down with TB over the last five or six years on a continuous basis.

I would like to comment first on the quality of staff. I acknowledge that the organisation's staff around the country are very capable, competent and do a very good job. I want to acknowledge that they have been very helpful in the majority of farms I have dealt with and that they are really effective operators on the ground. In particular, I refer to the likes of farm relief where they do an excellent job. I would say they know every ditch in the parish at this stage. They are really competent individuals.

I will ask about a few issues, the first of which is the delays in payments and working with farmers to make sure people get payments. While I have been in this meeting, one farmer texted me to say he has been waiting for a payment, and that 15 cows have gone down. There is an issue with slow payments. These cows went down last September but there is still no money in the bank regarding these cows. Is there a system in place to make sure these payments are fast-tracked so that farmers are not in a situation where they have to wait for payments?

Regarding the movement of reactors, has a defined timeline been put in place to make sure reactors can be moved? I realise there is an issue with finding locations and I realise it is a complicated job. Yet, is there a defined timeline regarding moving these reactors?

I want to ask about the new EBI status of bulls that is being proposed, as well as the new EBI status of some bulls that have high traits regarding health. Farmers will be going through a breeding programme in the next few months. I do not think the majority of farmers even realise that this health index is part of the EBI programme. Not only the health index, I do not think they know that TB is a part of it. This is probably not a question for the representatives. They famously said it was more a problem for genetics. Yet, it is a matter of getting that information out there. I have asked the Department what it is doing in the next three months in particular. I know most of the breeding operators. AI companies are doing roadshows at the moment, but when I went it was not mentioned at all. What is being done to get that information out there? As the representatives said, it is such a serious issue.

Regarding the farmers, mention was made of the vets, the valuers and the representatives. What training does the Department do with its vets, vets at a practice level, and the valuers who are entering farms? There could be awkward situations when animals go down. There could be health issues, mental health issues, strain or financial issues. You might meet a farmer at his worst possible moment, and this is no offence to the farmer in that moment. How will we deal with that? What are we doing to make sure that is being taken care of?

I compliment the organisation on the report it sent forward. I would like to focus on page 27 of the report, which gives really good information regarding statistics and figures. At the top of page 27, there is a graph with data from 2013 to 2023. The representatives might comment on that graph. My reading of it is that from 2013 to 2023, the dairy herd made up the majority of the increase in reactors. The report goes on to state that dairy animals in the graph itself come out at 63%, and the representatives might clarify this. That is the statistic - 63% are dairy animals. Is there a plan in place for that section of the industry? If you look at that figure, that is where the growth happened since 2013. That is the majority of the reactors. If we are to look at any statistic, that is the area that needs to be looked at.

With the deepest respect to Dr. Griffin, I do not believe that the sale of animals is the biggest issue when it comes to TB. It is my view that the majority of these herds are closed herds, but they might buy a stock bull every second year. They work with genetics a lot, and that is why AI is probably very important. Their transmission is going from animal to animal. Probably wildlife is giving TB to the first reactor, which is then transferring it on. That is the real core of our problem. What we will do about the dairy industry to make sure it is effective going forward to reduce the TB in those herds?

The other statistic I want to look at regarding the dairy industry states that 0.6% relates to dairy calves. We have a bizarre scenario, which is that if you are locked up tomorrow, none of your dairy calves can be sold. Nothing can move, because of the regulation that is in place. Yet, in the organisation's statistics, 0.6% are coming up as reactors. The hardship that causes for farmers in the springtime is indescribable. There is no outlet. It is important I acknowledge that there is no outlet for calves. No other farming group will take them because they do not take Friesan calves. They might be on the books of the organisation, but they do not actively take them. There is no slaughter system now, which is very logical and fair.

Regarding workload, mental health and financial health, you name it, how will we deal with that issue? Herds will be locked up in the next few weeks. Farmers will have calves until next June. They might not have the housing for them and they cannot move them. Statistically, less than 1% of them will go down. It is a very serious question for the farming community, and I do not have the answer to it. Something needs to be looked at regarding it, because there is no outlet this year. There is no outlet whatsoever. They are my opening questions, and I might come back in afterwards.

Dr. Conor O'Mahony

I will address the Senator's question on payments and then I will hand over to Dr. Barrett for most of the other questions. In terms of how payments are processed, reactors are disclosed at a test. A farmer is then contacted to choose a valuer of their choice.

A valuer comes out, values the animals and submits that valuation so that can either be appealed by the farmer or the Department. Then reactors are removed.

At the moment, the average time for reactors to be removed is between 17 and 18 days. It is more or less consistent with last year. On payment, we do payment runs every week. Payment runs issue, generally, assuming all necessary paperwork is supplied by the farmers. He may have to supply, if he is a dairy farmer, milk recording details, etc., to the valuer for the valuation to be complete. For 15 cows to have been removed in September and payment not made yet is unusual. The Senator can give me more details afterwards but, generally, that would be the exception. We have good, strong systems in place and they do work with regard to processing the payments. I cannot speak to that person but if the Senator might give me details later on, that would be fine.

Dr. Damien Barrett

First, I thank the Senator for the positive feedback on our staff on the ground. That is very much appreciated.

Mr. O'Mahony addressed the issue of the disclosed removal. From the time the regional veterinary office, RVO, is notified to slaughter, that is coming in around two days at the moment. There could be some administration. I want to highlight that it can be challenging for us to find out that it is for cattle, when cattle are plentiful. When cattle are not plentiful at slaughter, there will be more demand for them from the meat factories but then there are times when cattle are plentiful in the surge. Sometimes we have a surge of grass-fed cattle coming to slaughter and a surge in reactors at the same time, and that can make life challenging. Despite that, the average figure is usually two days from the regional veterinary officer being notified to the slaughter.

On the EBI, we met with the AI stations in July to discuss this issue of genetic resistance, to bring it to their attention and ask them to promote this with their clients. I am disappointed to hear that it was not something that was brought to the committee's attention. We specifically had that meeting so that word of this could be spread.

The next issue mentioned was mental health, and the stress that people are under. I completely appreciate that. It can be quite overwhelming for people, and people have a lot to take on together. Our colleagues in our farm safety section, the committee may be aware, had a conference on mental well-being two or three weeks ago. One of the senior people in that section spoke to our own veterinary inspectors last week about mental well-being and there is an initiative that the section is leading. It basically involves training for people so they can recognise when people are in distress. I want to emphasise that we are not going to make therapists and counsellors out of our own staff because they are not qualified to do that. However, the purpose of this training is that they can identify people who are in distress and, as diplomatically as possible, direct them to seek help. We accept that there can be a lot of sensitivities in such circumstances, and these can be difficult and sensitive conversations but this training will be made available to our staff.

The issue around the increase in reactors in the dairy industry and among dairy cows has been highlighted, and that really reflects the change in demographics in the national cattle herd. This has been the case since 2015 in particular but it was probably on the cards earlier than that. That is well recognised. The thing about dairy farming compared to other types of cattle farming is that it is more intensive. One has probably got higher stocking rates and animals being brought together twice a day with nose-to-nose contact in collecting yards. It should be remembered that this is a respiratory disease that is spread by respiratory means. There is no doubt about it; that is challenging. What is also challenging, especially in herds that were newly-established - and closed herds that are fairly stable were mentioned - is that we have evidence that these newly-established herds would have bought-in animals. They may well have bought-in animals from herds with recent TB histories.

One comes to mind where, this time last year, I came to review it. It was a large herd, and by the time I saw it, about 50 reactors had been removed. I looked and I saw that there were 70 animals that had been present at a previous breakdown. Some 60 of that 70 were present in another heard, so they were purchased in from another herd. The difficulty with our test is that sometimes, with the best will in the world, there may be animals moved that are carrying occult or latent infection. That is a challenge in the dairy herd, and we are probably living with some of the consequences of that for a while. When it gets rooted into a herd like the one I referred to, it has had a very intensive testing regime involving blood tests and enhanced blood tests, and it is still locked up 15 months since the first case. That is going to be a difficult herd to eliminate. The issue of cattle-to-cattle spread and residual infection is a difficult one. It can be difficult to get it out of a herd. As I said about the cattle-to-cattle transmission, there is greater transmission between them.

The fact that the bulk, or almost two thirds, of the reactors are dairy-bred cattle has been highlighted. That is a fact. The Senator has highlighted the stress of dealing with the calves. The trouble is we have looked at this, and these calves do not carry zero risk. Calves may be latently infected and not failing a test but a farmer could be moving them and spreading the disease. We have an outlet at the moment for these calves. They can be slaughtered. It is not the most pleasant of outlets but it is an outlet.

There might be an outlet. It is a very unsavoury option; I accept that. A majority of farmers would rather do anything but that.

Dr. Damien Barrett

Yes, I know that.

That outlet is probably not what the majority of us want. We need to find a solution and to work towards it.

Back in Covid-19 times, the date was changed on which calves could be moved to longer than 60 days. There was no massive jump in TB around Ireland off the back of that.

Dr. Damien Barrett

Maybe there is? That was three years ago, and now we are facing a surge.

They were a majority of Friesian bull calves, so looking at the statistics, bulls or steers went through the roof. At the moment, 67.6% are cow numbers. If we look at our TB problem, it does not happen with calves or younger animals to such a degree. Two thirds of it falls directly into the line of cows and more mature animals.

Dr. Damien Barrett

The detection of them is in more mature animals. My point is that they may be latently infected and carrying infection. If we talk about Covid-19, there is the silent carrier that nobody sees.

Absolutely but the majority of calves going to the mart would be male.

Dr. Damien Barrett

Well, the beef animals could be-----

Yes, but to me there are statistics that need to be worked out here. Dr. Barrett's table on page 27 is a unique piece of work. It outlines where we are with the industry itself. There was mention of vaccinations and we are not looking at vaccinations for the exportation of animals. We export younger animals on average; we do not export cows. The cows in our herd are usually either in lactation or they are going into the industry for whatever they do - I do not want to say it. Is there an option whereby we should be looking at vaccination for a certain section of our population of bovines because statistically TB is more likely to be prevalent in that section of bovines?

Dr. Damien Barrett

The difficulty with that is the milk from vaccinated cows and the produce, including milk powder, butter, etc., would be subject to the same rules as the meat, so we would not be able to export it.

Even with our pasture-----

Dr. Griffin wants to say something.

Dr. John Griffin

If that point is finished I want to come back on another point if that is all right. It concerns cattle movement. I do not want to give the impression cattle movement is the only factor that causes transmission of TB. Ultimately, there are two factors. As Dr. Barrett said, a herd does not get infected from nowhere. It either comes from other cattle or from wildlife, either directly or indirectly, and we have to deal with both sources. That is absolutely clear. The point I was trying to make is there is very strong scientific evidence that cattle movement is a really important factor in the transmission of TB. There are a number of reasons for that. First of all, there is very significant movement of cattle. It is something of the order of 1.3 million moves per year. We also have evidence there is a high level of movement from high-risk herds to low-risk herds, so that really is a mechanism for transmitting TB.

Also, as Dr. Barrett said, the test is not perfect. When a herd becomes free of tuberculosis and is derestricted there is still a strong possibility there could be some infected animals in that herd. Again, there is evidence to show there is a higher risk in animals that move from previously infected herds than from clear herds. That is evidence cattle movement can play an important role. The other point to mention is that it is not just the direct spread, so when an infected animal moves to a clear herd, it is not just the clear herd that becomes infected as the disease can by transmitted to badgers and deer, which can in turn retransmit it to cattle herds, so we kind of enter a vicious circle. Overall, it is essential we deal with this question. If we are to eradicate TB, we need to address issues about the movement of cattle. I wanted to make that point, but it is by no means the only factor and I completely agree with the Senator on that.

I thank Dr. Griffin. Can I ask a further question while there is voting?

I have a few questions I want to ask too. I will let the Senator back in.

I thank the Chair.

Maybe this was addressed when I went out, but I am curious about "high-risk" and "low-risk". One of the options presented was "Voluntary or mandatory informed purchasing, which would allow farmers better inform their management decisions in respect of their herd risk management when they are purchasing cattle". I do not argue with the sentiments of the statement, but the forum is then going to put a lower value on cattle that have a clear herd test. If I am in a mart and I put up on the board that these cattle are coming from a high-risk area for TB, the number of customers I am going to have around the ring will be significantly lower. If I have two clear herd tests I feel as a farmer that I should be allowed sell my stock on an open field. This is saying I can sell away, but the purchaser is going to be warned these cattle have a higher chance of failing a TB test going forward. I can see the logic of what the forum is saying, but what mechanism is it going to put in place to make up for the shortfall there will be in the sale price of those cattle?

Independent valuers are an essential part of the whole live valuation system. I have been lobbied by independent valuers, as have other people here, and they are not happy with the payment system they are operating under. They are saying there is an antiquated method of paying and if they go into a large depopulation it costs them money, whereas you would think the opposite would be the case, namely, a large depopulation would be financially lucrative for them. Is there any plan to sit down with the independent valuers and see whether their grievances can be ironed out? They are a key part of the whole TB scene. Live valuation is hugely important for farmers who have reactors. On that, where a restricted herd is allowed be sold to one of these classified finishing units, is there a mechanism for independent valuation of the stock going into those finishing units? Say there is a person who is overstocked and it is locked up and he is allowed depart to one of these finishing units. Is there an independent valuation system for them?

My last question goes back to the point made earlier about the intensity of dairying, the increase in herd size and the impact it has had on the number of reactors. Does Mr. O'Mahony feel zero grazing has had a negative impact on reactors? The grass comes in and cows eat what is before them. Is that a more dangerous way of grass consumption, rather than the natural consuming of grass in the paddock?

Mr. Conor O'Mahony

On the issue of risk, it is worth noting that a public accounts committee report on TB in 1994 came to the conclusion we will continue to have TB as a problem in this country when the interests of sellers supersedes the interests of buyers.

With respect to what the Cathaoirleach said about risk, we can slice and dice this slightly differently. Rather than applying a blunt instrument here, we could apply a system based on animals and their history and where they come from. There are different kinds of breakdowns. The Cathaoirleach mentioned high-risk and low-risk. The high-risk is now a breakdown involving three or more standard reactors and there is considered to be a higher risk of cattle-to-cattle transmission and on that basis a greater risk of latent infection within the herd. We could look at that in the first instance. We also need to look at animals that are going to be around for longer. There is a difference here with breeding animals. Some suckler animals could be around for ten or 12 lactations. With dairy animals, it could be seven or eight lactations. That is against an animal that is going to be finished before it is 13 months. Those beef animals are less likely to become reactors later. We need to consider that as well. We need to also a consider a breakdown where we have talked about a relapse when a farmer has had three or more standard reactors within the same cohort in a relatively short space of time. They are riskier herds.

I am not arguing that point, Dr. Barrett. The point I am making is they are not going to be as saleable in the sales ring. If a farmer has a reactor they get compensation and if their herd is locked up they get compensation, but if the Department is going to be using this description of a herd, it is going to be devaluing that stock for sale.

Mr. Conor O'Mahony

The truth of the matter is those animals are of a lesser value.

Mr. Conor O'Mahony

We are not devaluing those animals.

They have a lesser value because they are at a higher risk of failing a TB test in future.

Dr. Barrett is saying that these animals could have two clear tests after coming out of a reactor herd and the Department would still not be confident that they were not at risk of spreading TB.

Dr. Damien Barrett

We have data to show that these animals are at a significantly greater risk of failing another test within three years of a H breakdown.

I am not denying the logic of what the Department is proposing, but it has serious financial implications.

Dr. Damien Barrett

The animals we are most concerned about are breeding animals. This will have no implications for animals that are going for slaughter.

As to the risks in a zero grazing system, if grass is collected from badgers’ toileting areas next to their setts, it is possible that contaminated grass could be carried in. Another aspect of a zero grazing setup is that it will be in a farmyard and there will probably be more than grass being used for feed. Those other feeds will need to be kept bio-secure from badgers because some of them are very palatable to badgers. It is correct to say that zero grazing carries more risks, but they can be managed.

Dr. John Griffin

If cattle are indoors, they are in close proximity to one another, creating a greater risk of TB spreading from animal to animal. This is another factor that needs to be considered.

Mr. Conor O'Mahony

The Cathaoirleach asked about valuers and people who were restricted in selling to classified finishers. Last year, there was a competitive process to appoint a panel of valuers, which all valuers entered into, in terms of specified rates for carrying out valuations. There has been a great deal of discussion between us and the valuers in recent months. The door is not closed on those discussions. From our point of view, they are still ongoing.

As to whether there is an independent mechanism for allowing farmers who are restricted to sell to classified finishing units, the short answer is “No”. For us to facilitate or put in place a formal mechanism for valuing those animals when they are not reactors would be for us to step into a potential contractual negotiation between a buyer and a seller. In recent weeks, however, we have facilitated online auctions through marts and software that was developed during Covid. As a live example, let us say that I am a farmer with forward store cattle that had passed the test but I am restricted from selling on the open market. If I contacted a mart with this facility, there would be a live virtual auction of my cattle on my farm. The controlled finished units could bid online. This is about trying to facilitate competition for a cohort of animals that are valuable on the open market. Previously, there may have been just one purchaser going in to buy the animals. Now, the sale is opened up to potentially more purchasers. Culled cows are excluded, as are calves. This service is new - it was only launched in the past couple of weeks - and came on foot of a request from the marts, which felt it was needed and could be provided to facilitate competition in the scenario the Cathaoirleach described.

I am intrigued listening to this conversation. The witnesses touched on the matter I wish to raise when answering the Cathaoirleach’s questions. It has to do with the transmission of the disease. It was my understanding that it was transmitted nose to nose or by inhaling infected droplets exhaled by other animals, but the witnesses mentioned zero grazing and the defecation and urination of badgers. Can the disease be transferred between the badger and the bovine through ingestion as well? When airborne, how far can infected aerosol travel?

Dr. John Griffin

Traditionally, the belief about TB was that it was transmitted animal to animal directly. That is still the case. As to how far it can be transmitted, it is a short distance. For example, the UK’s Department for Environment, Food and Rural Affairs recommends that, if a farmer has a neighbour whose animals have tuberculosis, the farmer should set an electric fence 3 m inside. That should be sufficient to prevent nose-to-nose transmission.

There has been a change in recent years, in that there is much more evidence now of indirect transmission of tuberculosis. Pasture or troughs can become contaminated. There is not a great deal of evidence that badgers come into direct contact with cattle to a major extent. Likewise with deer.

That is my question. If we are talking grass or water troughs, that is ingestion, not inhalation. It can be transferred both ways.

Dr. John Griffin

There is still some debate about that. If a cow goes sniffing at a badger sett, it rumbles the ground and thereby creates an aerosol. This might be the mechanism. The infection in the animal is still in the respiratory system, so the organism ultimately gets into the lungs, but there is little doubt now, thanks to strong evidence, that indirect transmission is important. It is especially important in terms of badger setts, which are very contaminated environments, with badgers going in and out constantly, their latrines and so forth. This is a real risk. One bit of advice I would give farmers is to fence off their badger setts. They do not have to prevent the badgers from getting into the fields. They just have to fence off the setts so that their cattle do not have access to them indirectly. I hope I have answered the Senator’s question.

Dr. Barrett mentioned the courses being run to help departmental officials engage with the farming community. He stated that he was not a therapist in the field, but that identifying issues with mental health or people who might be stressed would be helpful. Have those courses been extended to private veterinary practices? In the majority of cases, they are the first people who deal with potentially shocked farmers. The valuers are the second people on the scene and, in many respects, are considered departmental officials even though they are not. Have they been given training on managing their initial reactions or engagement with farmers?

Dr. Damien Barrett

Regarding private vets, something has been piloted on a small scale. I cannot speak for my colleagues in the farm safety section, but my understanding is that, if any of the professionals dealing with farmers – vets, valuers and so on – were interested in being trained, that training would most certainly be made available to them.

Will the Department try to make it mandatory over time? How does it hope to roll out this system?

Dr. Damien Barrett

I do not believe we have the wherewithal to make it mandatory. I welcome the Senator’s suggestion, though, and we may be able to incorporate this into our TASAH training for private veterinary practitioners. A half an hour on such a course could be time spent usefully. I will bring that suggestion back with me.

Regarding the all-Ireland dynamic, we are what we are. What co-operation is there with the Northern Ireland authorities on TB? What are the differences between what happens in the North and what happens in the South? How does the dynamic work?

Dr. Damien Barrett

We have ongoing collaboration and discussion with our colleagues in Northern Ireland.

There are a couple of differences with the situation in the North. The herd incidence there is somewhere between 9% and 10%, I believe, while we are just below 5%. The North also does not have a wildlife programme like we have. One thing it does have and has done great work on is genome sequencing and tracing the isolates and DNA fingerprinting. We are doing that as well and we have made great progress in the last few years. A particular team in Amply Discovery in Belfast led the way on this. Overall, we are in regular discussion and we do co-operate.

Okay. My next question concerns where would be the best place to look for international experience. Northern Ireland is obviously one not to adopt. If we were, then, to look at a location that has worked and that has the same dynamics we have here regarding wildlife, because wildlife is our unusual factor compared with other countries that have TB issues, where would we look to as an international location that has managed to decrease the figures for the incidence of TB? Where is the best possible place and why is it the case? I ask that our wildlife issue be taken into consideration because we are far from a lab setting. This is not just dealing with how TB is transferred from one cow to another. It is the other added complications that make this so awkward.

Dr. John Griffin

That is a very good point. The example that comes to mind immediately in this regard is New Zealand. It had a very serious problem with TB and it also had a very serious wildlife problem with a creature called the possum. It came in from Australia about a century ago and caused very serious problems with TB in cattle, as well as in the possums themselves. New Zealand then started an eradication programme for possums, by laying poisons and so forth. That country has got to the stage now where it has gone from having hundreds, if not thousands, of herds having been infected to a situation now where there are about 50 herds infected. This has been done over perhaps the last 20 years.

The key thing there is the very high level of co-operation between the farmers and the authority, the equivalent of the Department of Agriculture, Food and the Marine. A new board was set up that was led by farmers and stakeholders. I think this had a major impact. Everybody in New Zealand is working together and they have had great success. The country is hoping to have TB eradicated from cattle by 2026 and from the possums by sometime in the 2040s.

Dr. Griffin is telling me that there is a TB test in New Zealand once every five years. Is that the case?

Dr. John Griffin

No. Going back to regionalisation, the country has been divided into different regions. I think there are about five of them. Where TB levels are very low, what the Senator is saying is probably correct. In the areas where the incidence of TB is high, though, or where there are many possums, for example, there would be TB testing every year or even more frequently than that. This is an example of a regional approach. The testing in New Zealand is done depending on the level of TB and the level of possum infection.

I thank Dr. Griffin.

I thank the witnesses very much for their contributions today. On the deer issue, I wish Mr. Cashman well. It is a project that is long overdue. Besides addressing TB, there is great merit in getting the deer population under control and back into their natural habitats. The agenda for our next public meeting has yet to be agreed. I wish everyone, the staff, the secretariat and all the members, a happy Christmas and a peaceful new year.

The joint committee adjourned at 7.54 p.m. until 5.30 p.m. on Wednesday, 17 January 2024.
