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 75 illnesses, including 22 hospitalizations and 1 death. The sandwich is potentially contaminated with E. coli bacteria likely due to the chain's supplier of slivered onions. A recall on the Taylor Farms raw yellow onions sent to restaurants was just announced due to a potential E. coli contamination. This specifically impacts McDonald's locations as well as other restaurant chains partnered with the supplier. Costco Just Recalled Salmon Due to Listeria Risk—Here's What to Know McDonald’s customers in the following states have been affected by this recall: Colorado, Kansas, Idaho, Iowa, Michigan, Missouri, Montana, Nebraska, Nevada, New Mexico and Oklahoma, Utah and Wyoming.
