Wolverine Packing Co., the company at the heart of a current E. coli recall, supplies over 250 meat brands with familiar names like Tyson.

The outbreak is linked to the same E. Coli strain that contaminated onions used by McDonalds and other fast food chains last month.

Ground beef is back in the hot seat this week as the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) has officially announced the recall of approximately 167,277 pounds of ground beef products.
