The CDC has issued a food safety alert regarding an outbreak of E. coli infections linked to McDonald’s Quarter Pounder hamburgers. The alert highlights that 49 individuals across 10 states have fallen ill due to the same strain of E. coli O157:H7, with the majority of cases reported in Colorado (27) and Nebraska (9).
Currently, 10 people have been hospitalized, including one older individual in Colorado who has sadly passed away. Additionally, a child is hospitalized due to complications from hemolytic uremic syndrome (HUS).
All individuals interviewed reported consuming food from McDonald’s prior to their illness, with many specifically mentioning the Quarter Pounder hamburger. While the exact ingredient responsible for the infections has not been pinpointed, investigators are concentrating on two potential sources: fresh slivered onions and fresh beef patties.
In response to the outbreak, McDonald’s has proactively withdrawn the slivered onions and beef patties used in Quarter Pounder hamburgers from locations in the affected states while the investigation is ongoing. As a result, these hamburgers may be temporarily unavailable in certain areas.
The CDC advises individuals who experience severe symptoms of E. coli infection after enjoying a Quarter Pounder to seek medical attention and inform their healthcare provider about their recent meal. Common symptoms of E. coli infection include intense stomach cramps, diarrhea (often bloody), and vomiting, typically appearing 3 to 4 days after exposure. Most individuals recover without medical treatment within 5 to 7 days, but some may develop severe kidney issues needing hospitalization.
For further information on E. coli, individuals can refer to the CDC website on Escherichia coli infection. For queries related to specific cases in their states, individuals are encouraged to contact their local health department.
