Vol. 122 No. 2

Adjournment Matter. - Experiments on Animals.

Thank you, a Chathaoirligh for allowing me to take this motion this evening. Some of my friends have been teasing me about this subject. They wonder about this newfound concern for animals that was not apparently part of my agenda up to now. In recent times we have all become more and more educated as to the interdependability of creation in the universe. According as the environment is threatened, we are coming to realise more and more how much the universe hangs together, as it were, and there is a genuine increase in people's concern for animal welfare. While I am aware of the extremes to which this can lead, nonetheless I am very happy to be a voice for those who most certainly have no voice at all so that when I go home tonight, if I do not gain any more graduate votes, I can look my cat straight in the eye. I am proud also to be president of the Irish Anti-Vivisection Society having succeeded the late John O'Donovan of RTE in that office. It is at their behest that I raise this matter.

I would like to outline to the House what is involved here. The Minister has responsibility for administering the Cruelty to Animals Act, 1876, which is the one governing painful scientific experiments on animals. When that Act was passed originally over 100 years ago there were very few animal experiments, perhaps a few thousand a year in what was then the United Kingdom of Great Britain and Ireland. In 1987, the last year for which figures are available, there were over three million animal experiments in Britain. In this country over 37,000 animals were used in experiments that were, according to the Act, calculated to give pain.

There is very little else forbidden under the 1876 Act. It gives the Minister very wide discretion. There is almost nothing that cannot be done to a live animal in a laboratory if a senior scientist says so and the Minister for Health accepts his view that it is done in the course of useful research and necessary for the success of that research. The Minister has a great deal of discretion under this long-standing Act but it has to be said that Ministers in our country have used their discretion in a very responsible way, as have their officials. There is no general complaint with the Department of Health on that score. One does not find here the kind of pointless, repetitive, cruel experimentation which one hears about in other countries and which one sometimes sees referred to on television. One does not hear of experiments being done, for example, for frivolous reasons such as testing cosmetics, brake fluid or household cleansers. Perhaps it is that it is not commercially worthwhile to do such tests here since most of them are done abroad. It is also true, to give the Department their due, that the Minister and his predecessors have applied the 1876 Act, inadequate and outdated as it is, in a very humane and conscientious fashion.

The real reason I bring this up this afternoon is that there is reason to believe that things are changing. In 1987, the last year for which we have figures, for the first time in several years the number of experiments on animals in the Republic of Ireland went up substantially — 37,178 animals were used in experiments in 1987 compared with only 31,315 the year before. This is an increase from 1986 to 1987 of over 6,000 animals, nearly one-fifth. That is one cause for concern.

There is another matter that is puzzling and that is that the number of experiments in which no anaesthetic was used has gone down substantially whereas there has been an enormous increase from under 3,000 to nearly 16,000 in the number of experiments that were conducted completely under anaesthetic. One might ask what is the grievance there; this is an apparently more humane development that more and more animals are being put under anaesthetic. However, it is not as obvious as it seems. The majority of experiments consist of animals being injected with substances which are to be used in the manufacture of drugs and other therapeutic preparations to find out whether they contain any impurities. These tests were not normally particularly painful or distressing so for that reason they were done without anaesthetics but also because, if one uses an anaesthetic, the value of the test can be called into question and its accuracy compromised.

The great increase in experiments conducted with anaesthetics in 1987 suggests that something of a different kind is happening, the kind of test that would have caused severe pain or distress if no anaesthetic had been used. So is there research of a significant scale of a different kind now being done that was not being done before? That is one of the things I would like the Minister to explain to the House. What lies behind these statistics?

There is also another point. In the previous ten years the number of experiments seems to have decreased but when there is a drop in the figures it may well be that some largescale research programme is being phased out or that money is not available because of the recession. So we are not sure that the drop in figures over a number of years is a real turning away. It now turns out that there was not a real reduction and that there was a substantial increase in numbers.

Real reduction in animal experiments will come only when researchers methodically turn to alternative methods of research and eliminate gradually the use of animals in their work. I am not an extremist in these matters. I do not believe that animal experiments are always wrong but I do believe — and I think every humane person believes — that they must be justified. The question arises as to whether scientific research on live animals is an old-fashioned laboratory tool, whether the best research is not conducted by alternative methods and whether the Minister is committed in principle to the replacement of animals in scientific research by alternative methods. That is something I would be glad of his informing the House about. There is no public indication from the Minister of his support for the development of non-animal alternatives. Admittedly, this all costs money. Experimental procedures have to be validated very carefully. Throughout the world it is the small animal welfare groups who have very little resources but who are backing the non-animal alternatives. Even if we have the right to use animals for purposes of life and death, we still have a moral duty to look for alternatives.

Finally, I would like to ask the Minister whether it is intended to look again at the 1876 Act. All this area is governed by an Act which is well over a century old, which was drafted in very different times. The world has moved on. I understand that the question of amending the Act may arise shortly anyway because the country will have to implement the Council of Ministers' directives on the care and treatment of laboratory animals. So, as in so many other areas, we may be told what to do by the Community. Pending that, I would urge the Minister to think about restricting animal experimentation in this country to bona fide medical research and to allow it where there is no non-animal alternative available and to put that by way of amendment into the Act. The Medical Research Bureau and the Irish Cancer Society have already accepted the principle that there should not be experiments on animals where there is an alternative available. The public in Ireland would, I am sure, overwhelmingly approve any such humane advances. Because of our particular cultural conditioning as a country we are not noted perhaps for our tender consciences about animals which is why I raised the personal point about myself in the first place; but at the same time our people are a decent people and would approve progressive and humane legislation and amendment of the law in this respect. In a way what the society I represent are asking is that the Minister put into law what is the humane practice in his Department already. The Irish Anti-Vivisection Society are appreciative of the co-operation they have had from the Department over the years. They pay tribute to the genuine humane attitude of the Department. What they are now asking is why can the existing good practice not be consolidated in law. It would be greatly to our credit in Ireland if we did not have to wait to be told to do this, if we gave the lead ourselves.

First, I am sure Senator Murphy will be pleased to note that I have been delegated responsibility under the 1876 Act by the Minister for Health so I suppose I am the appropriate person to answer in the House on this occasion.

Data in relation to animal experimentation licensed by me under the Cruelty to Animals Act, 1876 is collected by my Department on an annual basis. The most recent period for which complete data is available is 1987. In that year a total of 252 persons were licensed to perform experiments and a total of 37,178 animals were used in these experiments. The number of animals used in 1987 shows an increase in the number used over the preceding two years, 1985 and 1986, but is comparable with the numbers used in the years prior to then. The position year by year since 1983 is as follows:—

Number of Licence holders

Number of Animals Used

1983

233

36,288

1984

240

36,831

1985

199

32,136

1986

225

31,315

1987

252

37,178

The purpose for which the 37,178 animals used in 1987 may be categorised as follows:

Development of products used in medicine

13,685

Development of products used in veterinary medicine

1,701

Diagnosis of Disease

2,322

Study of Cardiovascular Disease

859

Study of Cancer

1,199

Study of Mental Disease

1,356

Other Diseases

2,670

Teaching and Learning

3,933

Other purposes (e.g. collection of antisera)

9,453

37,178

The various categories of animals which made up the total figure of 37,178 were the following:

Rabbits and rodents

33,215

Dogs and Cats

199

Horses, Donkeys, and other farm animals

2,318

Others (eg. fish, birds)

1,446

37,178

The overall increase in the 1987 figures over those for 1985 and 1986 is accounted for by an increase in the number of rabbits and rodents — mainly mice — used for the development of products used in medicine.

In 1986 a total of 8,696 rabbits and rodents were used for the development of products used in medicine. In 1987 a total of 13,659 rabbits and rodents were used. Most of this increase was accounted for by an increase in the numbers of mice used in the pharmaceutical industry for the acute toxicity testing of new materials used in the manufacture of medical devices. These procedures involved injection only. Surgical procedures were not involved.

I should mention that despite our developing pharmaceutical industry the scale of animal experimentation in this country continues to be very low in comparison with, for example, our European neighbours. In 1986 in the UK the number of animals used was in excess of 3 million. In The Netherlands for the same year the number of animals was in excess of 1.2 million. In Belgium approximately 1.2 million animals are also used annually. In Germany between 7 and 10 million animals per year are used. I quote these figures to put animal experimentation in this country into some perspective. Moreover, about 70 per cent of experimentation in this country consists of an injection only involving no surgical procedures.

This is not to say that we can be complacent at any stage about animal experimentation in this country. No experiment should be carried out on any animal unless it is justified. We are fortunate in that animal experimentation has always been tightly controlled under the Cruelty to Animals Act, 1876. This legislation — although a measure dating from Victorian times — has stood remarkably well the passage of time and the controls on experimentation under the Act are in advance of the controls in many countries where experimentation takes place on a greater scale.

Under the 1876 Act no person may carry out an experiment where pain is caused unless he has been licensed by me to do so. No place may be used for the carrying out of experiments unless it is registered by me. Applications for licences must, in the first instance, be supported by the signatures of the holders of certain offices prescribed in the Act. There are safeguards built into the Act in relation to the use of anaesthesia and for the killing of the animal if the effects of the anaesthesia wears off where pain is likely to continue or if serious injury has been inflicted. Each application for a licence is subject to scrutiny by an inspector appointed for the purposes of the Act. Medical officers of my Department and a number of veterinary officers of the Department of Agriculture and Food have been appointed as inspectors.

The inspector makes a recommendation to me on the licence application. Experimental facilities are also subject to inspection by the inspectorate. Experiments must be for bona fide purposes and no experiment is authorised where an alternative method is reasonably or practicably available. Where possible the licences granted are for clearly defined purposes and for the use of specific types and numbers of animals over a particular time.

The balance of medical and other informed opinion is that animal experimentation contributes to advances which lead to the protection of life and alleviation of suffering. Animal experimentation will therefore continue to be necessary in the public interest subject to proper safeguards. Alternative methods to the use of animals in all cases are not likely to be available for the foreseeable future. My objective, therefore, is to keep animal experimentation to a minimum consistent with my overall objective to protect public health and to ensure that where experimentation is necessary the animals do not suffer any unnecessary pain or discomfort.

As the Senator and the House may be aware, there is in existence a Council of Europe Convention for the Protection of Vertebrate Animals used for Experimental and other Scientific Purposes. There is also a Eurpean Community directive due for implementation by 24 November, 1989 on the approximation of laws, regulations and administrative provision of the member states regarding the protection of animals used for experimental and other scientific purposes.

In so far as this country is concerned the positive features of the directive are as follows: it broadens the definition of experiment and includes some procedures on animals not subject to control under the 1876 Act; under the 1876 Act State control was exercised only over user establishments i.e. the experimental laboratory. Under the directive establishments which supply and breed animals for experimental purposes must be registered and a proper level of housing, care and accommodation of the animals must be observed; it is explicit as to the circumstances in which anaesthesia may be dispensed with in animal experiments. No authorisations to dispense with anaesthesia may be granted in the case of serious injuries which may cause severe pain. If an animal is in considerable pain once anaesthesia has worn off and if it is not possible to treat it with pain-relieving means the animal must be immediately and humanely killed; it makes provision as to how an animal is to be treated and cared for after the experiment and the extent to which an animal may be used in further experiments. Stray animals of domestic species must not be used. The directive seeks to encourage research into the development and validation of techniques which could provide the same level of information as that obtained in experiments using animals.

My Department are currently taking steps to implement the directive. Implementation of the directive will also enable this country to become a party to the Council of Europe Convention.

In conclusion I would like once again to reassure the House of my concern to strike the correct balance between the need for animal experimentation and the need to keep such experimentation to a minimum and to protect experimental animals from any undue pain.

I would like to express my appreciation to Senator John A. Murphy for raising this matter in the Seanad and giving me an opportunity to explain the current position in my Department in relation to experimentation on live animals and in relation to the preparation of legislation which will be necessary to comply with the EC directives.

The Seanad adjourned at 4 p.m. until 2.30 p.m. on Wednesday, 22 February 1989.
