The FDA reported that investigators are working to determine if slivered onions or beef patties are the source of the E. coli O157:H7. Meanwhile, Taylor Farms, the supplier of the onions, recalls certain yellow onions sent to food service/restaurants. McDonald’s temporarily stopped selling the Quarter Pounder and the slivered onions in the affected states. As of October 24, 75 people infected with the outbreak strain of E. coli O157:H7 have been reported, and 22 were hospitalized from 13 states (CO, IA, KS, MI, MO, MT, NE, NM, OR, UT, WA, WI, and WY). Illnesses started from September 27, 2024, to October 10, 2024. Of 61 people with information available, 22 have been hospitalized, and two people developed hemolytic uremic syndrome, a serious condition that can cause kidney failure. One death has been reported from an older adult in Colorado. Of the 42 people interviewed, all 42 (100%) reported eating at McDonald’s, and 39 reported eating a beef hamburger. While the investigation is ongoing, Taylor Farms, the supplier of slivered onions for the affected McDonald’s locations, has initiated a voluntary recall. Recalled yellow onions were sold to additional food service customers. Customers who received recalled onions have been directly notified of the recall. The FDA is unaware of any cases or affected products outside of the United States. @ https://www.fda.gov/food/outbreaks-foodborne-illness/outbreak-investigation-e-coli-o157h7-mcdonalds-quarter-pounders-october-2024?utm_medium=email&utm_source=govdelivery
