Testing has confirmed that beef lasagna produced by food manufacturer Findus contained horsemeat, Britain's Food Standards Agency (FSA) said on Thursday.
Findus, a European food group which is behind brands including Young's and The Seafood Company, began a recall of its beef lasagna from retailers earlier in the week on advice from its French supplier, Comigel.
Investigations into suppliers have been launched in recent weeks after revelations that beef products sold at major British supermarkets including Tesco and fast food chain Burger King contained horsemeat.
