Horsemeat scandal: EU urges DNA tests of processed beef

The EU is urging members to conduct random tests to tackle a widening scandal over mislabelled horsemeat.
All members should carry out DNA tests on processed beef for traces of horsemeat for three months from 1 March, the health commissioner Tonio Borg said.
Horsemeat should also be tested for the presence of the veterinary medicine phenylbutazone ("bute"), he added.
Prime Minister David Cameron has issued a stern warning to anyone in Britain involved in passing off horsemeat as beef, saying they will face the "full intervention of the law".
