I propose to take Questions Nos. 25 and 37 together.
The monitoring of live sheep for radiation commenced last summer and covered flocks in upland areas with peaty soil where the rainfall was heavy when the radiation plume from the Chernobyl nuclear accident passed over this country in early May 1986.
The monitoring covered flocks in upland areas of Counties Donegal, Sligo, Leitrim, Roscommon, Mayo, Galway, Waterford, Kilkenny, Louth and Wicklow. A summary of the results of this monitoring was published in a joint statement issued by my Department and the Nuclear Energy Board on 4 February 1988. Briefly the monitoring showed that 98 per cent of the sheep tested were found to have radio-caesium levels below the internationally accepted action level of 1,000 becquerels per kilogram. The 2 per cent which showed levels higher than the 1,000 becquerels were, for the most part, sheep retained on farms for breeding purposes.
The Nuclear Energy Board report referred to by Deputy Stagg indicated that 89 of the 130 farms (68 per cent) on which live monitoring of sheep was conducted could be regarded as having flocks with more than one animal per thousand having a radio-caesium level over 600 becquerels per kilogram. It did not indicate that 68 per cent of the sheep in the county could be affected by high levels of radiation.
The normal practice in these upland areas is to move the lambs to lowland pasture for a period of two to four months prior to slaughter. This move to lowland pasture results in a halving of caesium levels every two weeks, which ensures that the sheep, even the limited number over 1,000 becquerels per kilogram when on the mountain, are well under the EC safety standard of 600 bq. per kg. for meat at time of slaughter. This is confirmed by the live monitoring of sheep which is also conducted at slaughter premises and the monitoring of samples of sheepmeat at butchers shops throughout the country.
This programme of monitoring will be continued so as to ensure that sheepmeat sold for consumption does not represent any health problem and that there is no cause for any consumer concern. Last month's results further confirm that our sheepmeat is well within specified limits; no animal tested exceeded 600 bqs. per kg. and over 96 per cent were under 100bqs. per kg. Our vigilance at point of slaughter is the most effective and reassuring measure we can take not only for consumers but for the image of our food products in general.
Our export trade in sheepmeat is with member states of the EC and we have not experienced any difficulty in meeting the EC limit of 600 bq. per kg.
