Medical officer says bute poses very low risk to humans

Eight horses, killed in the UK, tested positive for the painkiller bute and six may have entered the food chain in France, the Food Standards Agency said.

Some 206 carcasses were tested, with eight found to contain phenylbutazone.

England's chief medical officer Prof Dame Sally Davies said an individual would have to consume vast quantities of horsemeat containing bute to be at risk.
