US fast-food chains including Burger King, KFC and Taco Bell have pulled fresh onions from some restaurants after an E coli outbreak linked to McDonald’s Quarter Pounder sandwiches sickened dozens of people.
Burger King’s parent company, Restaurant Brands International, and Yum Brands, which operates Taco Bell, Pizza Hut and KFC, made the announcement on Thursday as McDonald’s named a California-based supplier as the source of onions linked to the food poisonings.
