RELATED: HORSE MEAT FOUND IN BRITISH BURGERS, SUPERMARKET CHAIN APOLOGIZES TO HORRIFIED PUBLIC



The revelations have shaken Ireland in particular, because beef exports are a key industry. Irish government officials and an Irish meat company have blamed meat imported from Poland, but Polish authorities say they have found no evidence backing those claims.



Findus UK apologized to customers and said it was confident it has "full resolved" the supply-chain issue. "We understand this it is a very sensitive subject for consumers and we would like to reassure you we have reacted immediately," the company said.



Catherine Brown, chief executive of the U.K. Food Standards Agency, said that following its investigations into Findus, the agency is demanding more comprehensive meat testing from the food business "in order to demonstrate that the food it sells and serves is what it says it is on the label."



"We are demanding that food businesses conduct authenticity tests on all beef products, such as beef burgers, meatballs and lasagna, and provide the results to the FSA. The tests will be for the presence of significant levels of horsemeat," she said in a statement.



Comigel earlier this week had advised Findus — and the store chain Aldi — to remove frozen beef lasagna from store shelves. Supermarket chain Tesco also decided to withdraw its spaghetti bolognese, which was produced by Comigel.
