A California-based produce company was the source of fresh onions linked to a deadly E. coli food poisoning outbreak at McDonald’s, officials with the restaurant chain said Thursday. Meanwhile, other fast-food restaurants — including Taco Bell, Pizza Hut, KFC and Burger King — pulled onions from some menus.

First announced by the agency on Tuesday, the outbreak was originally reported after sickening 49 across 10 states and killing one. As of Oct. 24, the now 75 total illnesses across 13 states included 22 hospitalizations and one death in Colorado.
