According to the Centers for Disease Control and Prevention, a recent E. coli outbreak can be traced back to McDonald’s “Quarter Pounder” hamburgers. The outbreak has resulted in 49 recorded illnesses across 10 states, with one confirmed death. Health experts are rushing to determine the specific source of the contamination, with two leading suspects: slivered onions and quarter-pound beef patties.
The cases, recorded between September 27 and October 11, predominantly occurred in Colorado and Nebraska, but other states were also affected. Ten people have been hospitalized, and one child is being treated for hemolytic uremic syndrome, a severe kidney disorder caused by E. coli infections. The CDC has warned that the number of infections may increase as the investigation progresses.
In response to the outbreak, McDonald’s has halted the usage of slivered onions and quarter-pound beef patties in numerous states, including Colorado, Utah, Wyoming, and portions of Kansas, Idaho, and Missouri. The corporation is working with health authorities to ensure consumer safety while the inquiry is ongoing.
“Our top priority is the safety and well-being of our customers,” said Cesar Piña, McDonald’s Chief Supply Chain Officer. “As a precautionary measure, we’ve stopped serving slivered onions and pulled Quarter Pounders from menus in affected areas while we work closely with the CDC and FDA to identify the source.”
The slivered onions are thought to come from a single source, who is being investigated to see whether other restaurants would be affected. The FDA is also involved, inspecting the supply chain and tracking the movement of possibly tainted products.
Understanding E. Coli: What Are the Risks?
E. coli bacteria are prevalent in the intestines of humans and animals. While most strains are harmless, some, like E. coli O157, release toxins that can cause serious sickness. Symptoms often include severe stomach cramps, diarrhea, vomiting, and fever, which develop three to four days after exposure. While most patients recover within a week, rare cases can lead to life-threatening consequences, such as renal failure.
Young children, the elderly, and those with compromised immune systems are all at a higher risk. Hemolytic uremic syndrome, an uncommon but deadly illness caused by E. coli, can result in renal failure and requires rapid medical intervention. The CDC advises anyone having symptoms after eating a McDonald’s Quarter Pounder to seek medical attention right once.

Food Safety Challenges Continue for McDonald’s?
The E. coli epidemic at McDonald’s is the most recent in a series of food safety concerns in the fast-food business. Earlier this year, 12 million pounds of beef were recalled owing to potential listeria contamination, and a listeria outbreak connected to deli meats claimed several lives. The current event has also had an impact on McDonald’s stock performance, with shares falling 9% on the New York Stock Exchange following the announcement.
This is not McDonald’s first contact with E. coli-related problems. Six children in Alabama were hospitalized in 2022 after eating E. coli-contaminated chicken McNuggets, reflecting recurring concerns over the fast-food giant’s food safety practices.
Current Investigation Status and Next Steps
Health experts, including the CDC, FDA, and USDA, are working feverishly to identify whether the contamination came from slivered onions or beef patties. While additional McDonald’s menu items such as the Cheeseburger, Big Mac, and Double Cheeseburger have not been linked to the incident, the inquiry is still ongoing. Authorities are warning customers that the situation could change, with additional illnesses being reported in the coming weeks.
Preventing E. Coli Infections: What You Need to Know
Proper food handling and preparation are essential in preventing E. coli infections. Is E. coli killed by cooking? Yes, cooking food to an internal temperature of 160°F (70°C) or higher effectively eliminates the bacteria. However, other measures, such as washing hands thoroughly, cleaning kitchen surfaces, and avoiding cross-contamination, are equally important in reducing the risk of infection.
Consumers are encouraged to stay updated on the situation and practice food safety measures, especially if they have recently consumed McDonald’s Quarter Pounders.
