UPDATE 2-Cargill recalls possibly tainted beef sold at Canadian Walmarts

By Allison Martell and Rod Nickel TORONTO/WINNIPEG, Manitoba (Reuters) - Cargill [CARG.UL], Canada's biggest beef processor, is recalling ground beef sold by Wal-Mart Stores Inc that may be contaminated with E. coli, the Canadian Food Inspection Agency (CFIA) said on Tuesday. The agency said there have not been any reported illnesses associated with Cargill Meat Solutions' "Your Fresh Market" brand beef, which was sold in Alberta, British Columbia, Manitoba and Saskatchewan. The recall comes about two years after Canada recalled millions of pounds of beef produced at the former XL Foods plant at Brooks, Alberta. At least 18 people became ill in 2012. E. coli bacteria can cause illness, or even death, and symptoms include severe stomach cramps, vomiting and diarrhea. Cooking meat to the correct internal temperature kills the bacteria. Cargill is recalling 31,000 pounds of beef produced at its Calgary, Alberta, plant, said Connie Tamoto, spokeswoman for the privately held company's Canadian division. Minnesota-based Cargill is the world's biggest agribusiness conglomerate. Tamoto said Cargill was not recalling any beef from the United States or other countries. Wal-Mart spokesman Alex Roberton said the affected products are no longer for sale and are past the expiration dates of Nov. 28 and 29. Customers who return products purchased from Wal-Mart will get refunds, he said. The CFIA said test results triggered the recall. Its investigation may lead to the recall of other products, the agency said. (Editing by Franklin Paul, Jeffrey Benkoe and Steve Orlofsky)
