asked the Minister of Agriculture, Fisheries and Food whether he will list the pesticides which have been approved for use in the United Kingdom and in respect of which toxicological data were submitted which originated from the International Bio Test laboratory.

To answer my hon. Friend's question in full would involve disproportionate cost. International Bio Test laboratories were involved in producing studies to support the registration of pesticides for over 10 years until 1978, but the question of fraudulent studies arose chiefly in the later years. In 1978 the United States authorities listed 123 products (both active ingredients and formulations) whose United States registration depended in part on IBT studies from all periods of the company's operation. The United Kingdom's examination in 1980 demonstrated 12 active ingredients which were of concern as a result and the Government's handling of these cases was detailed in the reply from my predecessor in this post to the hon. Member on 9 June 1986. No estimate is available of the number of studies which were judged at that time to give no grounds for concern.
