David Cameron: 'Horsemeat story is shocking'

Prime Minister David Cameron has said it is "completely unacceptable" that "people have been found to be eating horse when they thought they were eating beef".

The Food Standards Agency has asked UK firms to test all processed beef foods, but said it did not "suspect there is any health issue with frozen food".

People should not throw away frozen meat products in the wake of the revelations about horsemeat in Findus lasagne, the food minister David Heath has said.

Mr Cameron stressed said that "there is no reason to believe that any frozen food currently on sale is unsafe or a danger to health".
