Findus withdrew the beef lasagne products after its French supplier, Comigel, raised concerns about the type of meat used in the lasagne.
We have no evidence to suggest that this is a food safety risk. However, the FSA has ordered Findus to test the lasagne for the veterinary drug phenylbutazone, or 'bute'. Animals treated with phenylbutazone are not allowed to enter the food chain as it may pose a risk to human health.
The Findus beef lasagne was distributed to the main UK supermarkets and smaller convenience stores. Findus has already begun a full recall of these products.
People who have bought any Findus beef lasagne products are advised not to eat them and return them to the shop they bought them from.
