British supermarket chain finds horse drug in beef

British supermarket chain Asda said on Tuesday very low levels of the horse pain-killing drug phenylbutazone, also known as bute, had been found in horsemeat discovered in tins of corned beef in the first such case in Britain.


Britain's Food Standards Agency (FSA) said the level of the drug, which is banned from entering the human food chain, posed a low risk to human health, as results showed it contained 4 parts per billion. (Reuters)
