Big-name fast food chains, including Taco Bell, KFC, Pizza Hut, and Burger King, are reportedly pulling onions off their menus in certain locations amid a deadly, multistate outbreak of E. coli O157:H7 linked to McDonald’s Quarter Pounders.
Though the source of the outbreak bacteria has not been confirmed by the Centers for Disease Control and Prevention, the leading suspects are the beef patties and the sliced onions used on the popular burger.
On Wednesday, McDonald’s onion supplier Taylor Farms recalled peeled and diced yellow onion products, according to a notice from US Foods, a supplier of food service operations.
