HC Deb 30 November 1990 vol 181 c496W
Mr. Ron Davies

To ask the Secretary of State for Northern Ireland if he has any information relating to adverse effects on human health resulting from the illegal use of beta-agonists.

Dr. Mawhinney

I am not aware of any adverse effects on human health in this country resulting from the illegal use of beta-agonists. However, I understand that the national epidemiology centre, Madrid has investigated a possible link between outbreaks of food poisoning in Spain and the illicit use of clenbuterol in cattle feed.
