(Chicago. IL) — McDonald’s believes slivered onions may be the cause of an E. Coli outbreak that’s killed one person and sickened nearly 50 others. The chain says the onions in question came from a single source, and were packaged and sent to restaurants raw. McDonald’s has pulled the sliced onions and beef patties used for their Quarter Pounder burgers in Colorado, Kansas, Utah, Wyoming and portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico and Oklahoma.
The CDC says they expect the number of illnesses to rise in the coming days.
