McDonald’s says onions from California-based produce company linked to deadly E. coli outbreak [Video]

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.

McDonald’s officials said that Taylor Farms, of Salinas, California, sent onions to one distribution facility, which led the fast-food chain to remove Quarter Pounder hamburgers from restaurants in several states. McDonald’s didn’t say which facility it was.

An outbreak tied to the burgers has sickened at least 49 people in 10 states, including a person who died, federal health officials have said. Investigators said they were focused on slivered onions as a potential source of the infections.
