McDonald’s E. coli Outbreak Investigation: What You Need to Know
Recent reports of an E. coli outbreak have raised concerns among McDonald’s customers, particularly those who enjoy the Quarter Pounder. The US Centers for Disease Control and Prevention (CDC) has launched an investigation into the issue, and McDonald’s has already taken action to address potential contamination sources. Here’s a detailed look at what we know so far.
Quarter Pounders Under Scrutiny
The CDC issued a food safety alert after dozens of people reported symptoms consistent with E. coli infections after consuming Quarter Pounder sandwiches at McDonald’s. While a specific source of contamination has yet to be confirmed, there are strong indications that either the slivered onions or beef patties used in the Quarter Pounders might be responsible.
To ensure customer safety, McDonald’s has stopped using these ingredients in several states, including Colorado, Utah, Kansas, Wyoming, and parts of other states like Iowa, Montana, Nebraska, and Oklahoma. The Food and Drug Administration (FDA) also mentioned that diced onions and other types of beef patties used in McDonald’s menu items are not implicated in this outbreak.
E. coli: What It Is and Why It’s Serious
Escherichia coli (E. coli) is a bacteria commonly found in the environment, foods, and intestines of people and animals. While most strains are harmless, certain types can cause serious health issues. People can become infected by consuming contaminated food or water, and symptoms usually begin 3-4 days after exposure. Common symptoms include:
- Severe stomach cramps
- Diarrhea (which can sometimes be bloody)
- Vomiting and fever
Although many individuals recover within a week, severe cases can lead to kidney problems and even require hospitalization. Those most at risk include young children, older adults, and individuals with weakened immune systems.
Impact of the Outbreak
According to the CDC, the E. coli outbreak linked to McDonald’s has led to at least 10 hospitalizations, including a child diagnosed with hemolytic uremic syndrome (HUS), a serious kidney complication. Sadly, one older person has died due to the infection.
Most reported cases are from Colorado and Nebraska, but infections have also been identified in other states like Iowa, Missouri, Montana, Oregon, Utah, Wisconsin, and Wyoming. The CDC expects the number of reported cases to rise as the investigation continues.
Fast-Moving Investigation
The CDC has labeled this investigation as “fast-moving,” and cases are being reported on a rolling basis as officials work to link genetic strains of the bacteria. Illnesses have been reported from September 27 to October 11, and the start date might be adjusted as earlier cases come to light.
Efforts are ongoing to identify and eliminate all potential sources of the outbreak to prevent further infections. Such outbreaks often decline once the contaminated food is removed from the supply chain, but thorough investigation is crucial.

McDonald’s Response: Safety Measures and Changes
McDonald’s has assured customers that it is safe to dine at their restaurants. The company has temporarily removed Quarter Pounder sandwiches from menus in affected states and taken steps to revise their ingredient supply chain. According to Joe Erlinger, President of McDonald’s USA, “We are very confident that you can go to McDonald’s and enjoy our classics without getting sick.”
McDonald’s also emphasized its food safety protocols, which include:
- Daily temperature checks
- Hourly handwashing for employees
- Cooking Quarter Pounders to temperatures that exceed FDA guidelines
Foodborne Illnesses on the Rise
This E. coli outbreak comes at a time when foodborne illnesses are on the rise in the United States. CDC data shows that in 2023, there were over 5 E. coli infections for every 100,000 people, marking a 25% increase compared to five years ago. Although Salmonella rates haven’t increased, other foodborne illnesses like Campylobacter have also surged.
Recent recalls, such as those by Boar’s Head and BrucePac, have also highlighted the importance of food safety measures across the industry. Ensuring safety protocols at all stages, from production to distribution, remains a top priority for the CDC and food companies alike.

What Should Consumers Do?
If you’ve recently consumed a Quarter Pounder from McDonald’s and are experiencing severe E. coli symptoms such as high fever, persistent diarrhea, or vomiting, it is advisable to contact a healthcare professional immediately. The CDC continues to monitor and investigate this outbreak to prevent further cases.
As the investigation progresses, consumers should stay updated on food safety alerts and be aware of the potential risks associated with this outbreak. McDonald’s, in the meantime, is taking steps to ensure that affected ingredients are no longer in their supply chain and is committed to serving safe, quality food.
