The Centers for Disease Control and Prevention (CDC) has reported an E. coli outbreak linked to McDonald’s Quarter Pounder hamburgers, affecting dozens of people across the United States. As of now, 49 individuals from 10 states have fallen ill, with most cases concentrated in Colorado and Nebraska. The outbreak has prompted McDonald’s to remove certain ingredients from stores in the impacted regions as a precaution.
States Impacted by E. coli Outbreak
The strain of E. coli identified in the outbreak is E. coli O157:H7, known for causing severe intestinal infections. Colorado has seen the most cases, with 27 reported, while Nebraska follows with nine cases. Other states with reported infections include Illinois, Iowa, Kansas, and more.
At least 10 people have been hospitalized, including a child suffering from hemolytic uremic syndrome (HUS), a condition that affects the kidneys. Unfortunately, an older person in Colorado has died from complications related to the infection, according to the CDC.
McDonald’s Response and Ingredient Investigation
The CDC’s investigation has revealed that all affected individuals had consumed McDonald’s before falling ill, with most reporting that they ate Quarter Pounder hamburgers. Two ingredients are currently under scrutiny: fresh slivered onions and fresh beef patties, both of which were used in the Quarter Pounder and sourced from a single supplier.
McDonald’s has proactively removed these ingredients from stores in the affected states, leading to a temporary unavailability of Quarter Pounders in some areas. Cesar Piña, McDonald’s North America Chief Supply Chain Officer, confirmed that the slivered onions were likely sourced from one supplier serving three distribution centers.
In a statement, McDonald’s USA President Joe Erlinger emphasized that this decision was made in close consultation with the CDC and that the majority of menu items remain unaffected.
Understanding E. coli and Its Symptoms
E. coli bacteria are common and often harmless, but certain strains, like O157:H7, can cause serious illness. Symptoms of an E. coli infection typically appear three to four days after exposure and include severe stomach cramps, bloody diarrhea, and vomiting. Most people recover within five to seven days, but in severe cases, HUS can develop, potentially leading to kidney failure.
The CDC advises individuals experiencing severe symptoms, especially those who recently consumed a McDonald’s Quarter Pounder, to seek medical attention immediately.
As McDonald’s continues to work with health authorities to resolve the outbreak, consumers in affected regions should stay informed about any new developments.
