Oct 30, 2024, 10:58 PM

An E. coli outbreak linked to McDonald's has been traced to fresh, slivered onions used in their Quarter Pounder hamburgers. The Centers for Disease Control and Prevention (CDC) confirmed that these onions, which are no longer available for sale to food service operators, are the likely source of the illness. US health officials have identified more cases of E. coli and are inspecting an onion grower in Washington. The onions were not likely to have reached grocery stores or consumers directly.
