A CDC Food Safety Alert has been issued concerning an outbreak of E. coli infections connected to McDonald’s Quarter Pounders.
According to the latest update, 49 individuals from 10 different states have reported illnesses caused by the same strain of E. coli O157:H7. The majority of cases are in Colorado, with 26 reported infections, while Nebraska has 9 cases.
Among those affected, 10 people have been hospitalized, and unfortunately, one elderly individual in Colorado has died. Additionally, one child is receiving treatment for complications related to hemolytic uremic syndrome (HUS).
All individuals interviewed confirmed having eaten at McDonald’s prior to falling ill, with most specifically naming the Quarter Pounder hamburger as their recent meal.
Although the specific ingredient causing the outbreak has not been pinpointed, investigators are currently focusing on fresh slivered onions and fresh beef patties. In response to the outbreak, McDonald’s has taken proactive measures by removing the slivered onions and beef patties used in Quarter Pounder hamburgers from restaurants in the affected states while the investigation is ongoing. As a result, Quarter Pounder hamburgers may be temporarily unavailable in some locations.
Safety Recommendations:
Individuals who experience severe symptoms of E. coli infection after consuming a Quarter Pounder hamburger at McDonald’s should seek medical attention immediately and inform their healthcare provider about their recent meal.
E. coli Symptoms:
Common symptoms of Shiga toxin-producing E. coli infection include severe stomach cramps, diarrhea (often bloody), and vomiting.
– Symptoms generally appear 3 to 4 days after exposure to the bacteria.
– Most people recover without medical intervention within 5 to 7 days.
However, some individuals may develop serious kidney complications known as hemolytic uremic syndrome (HUS), which may require hospitalization.
