The frozen food company, Findus UK, has confirmed that horsemeat has been found in its beef lasagne.
Findus says the product was made by a third-party supplier and has apologised to its customers.
The Food Standards Agency said that some of the Findus samples consisted of between 60 and 100% horsemeat, but added there was no evidence it was a food safety risk.
