E. Coli Outbreak Linked to McDonald’s Quarter Pounders

The Food and Drug Administration just alerted consumers of an active E. coli outbreak investigation impacting 12 states. The source of this outbreak is being linked to a popular McDonald’s sandwich.

The McDonald’s Quarter Pounder has likely been the cause of 49 illnesses, including 10 hospitalizations and 1 death. While the sandwich is potentially contaminated with E. coli bacteria, investigators are still determining whether the beef patty or the slivered onions is the affected ingredient. McDonald’s stores in the following states have temporarily stopped serving Quarter Pounders: Colorado, Kansas, Utah and Wyoming, as well as certain areas of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico and Oklahoma.

E. coli bacteria can cause serious foodborne illness, with common symptoms like stomach cramps, nausea, vomiting, diarrhea and fever. It can be more severe for young children, those age 65 or older and for immunocompromised individuals. The last reported illness was on October 11, 2024, but if you recently ate a Quarter Pounder at McDonald’s and are experiencing any of these symptoms, contact your health care provider immediately.

While there are no recalls connected to this alert, EatingWell will continue to keep you updated on the latest information surrounding this multistate outbreak.
