Now Horse Meat Found in Lasagna Findus pulls products from UK shelves, but concerns rise about food safety By Mark Russell, Newser Staff Posted Feb 8, 2013 9:20 AM CST 44 comments Comments Findus Beef Lasagne photographed in a shop in Jarrow, England, earlier today. (AP Photo/Scott Heppell) (Newser) – First British and Irish consumers were aghast to discover horse meat in their hamburgers. Now, horse meat is turning up in frozen beef lasagnas, with 11 of 18 tested Findus products containing horse meat in the 60% to 100% range, reports the AP. Findus pulled its beef lasagnas from stores and apologized immediately, saying it had "fully resolved" issues with its meat supplies. While horse meat is not considered a hazard per se, food safety officials are testing the meat for the veterinary drug phenylbutazone, which is banned from entering the food chain. Many food officials are pointing fingers at Irish beef exporters, who in turn are blaming Polish suppliers. The UK Food Standards Agency is calling for more comprehensive meat testing to ensure labels accurately represent products.
