A major food safety investigation is underway after an outbreak of E. coli O157infections was linked to McDonald’s Quarter Pounder burgers.
On Tuesday, October 22, 2024, federal, state, and local organizations, including the FDA, CDC, USDA, and FSIS, announced that they are investigating these reports across multiple states. While the exact cause of the outbreak is still unknown, most of those affected reported eating some version of a McDonald’s Quarter Pounder.
What’s Been Affected?
McDonald’s has responded to the investigation by temporarily removing both the slivered onions and fresh beef patties used in their Quarter Pounders. Other menu items, including those with diced onions and frozen beef patties, are not currently under suspicion.
This issue seems to specifically affect the Quarter Pounder family of burgers, which includes:
- Quarter Pounder with Cheese
- Quarter Pounder with Cheese Bacon
- Quarter Pounder Deluxe
- Double Quarter Pounder with Cheese
The main concern stems from the fact that these sandwiches use fresh beef patties, which differs from other McDonald’s burgers that rely on frozen patties. The slivered onions, which are also used exclusively on these burgers, have been flagged as a possible source of the contamination, although the investigation is ongoing.
States Affected by the Outbreak
Reports of E. coli infections have surfaced in several states, prompting McDonald’s to stop serving the implicated beef and onions in the affected areas. The following states are part of the investigation:
- Colorado
- Kansas
- Utah
- Wyoming
- Iowa
- Missouri
- Montana
- Nebraska
- Nevada
- New Mexico
- Oklahoma
- Parts of Idaho
At this time, it’s unclear how many people have become ill or the severity of their conditions, as authorities are still compiling data. McDonald’s has made it clear that it is working with investigators to ensure customer safety.
What Is E. Coli O157?
E. coli O157is a particularly dangerous strain of Escherichia coli bacteria. While not all E. coli are harmful, this strain can lead to severe health issues. Symptoms typically appear within a few days of exposure and can include:
- Severe stomach cramps
- Diarrhea (often bloody)
- Nausea and vomiting
- Fever
In serious cases, an E. coli infection can lead to hemolytic uremic syndrome (HUS), a life-threatening condition that can result in kidney failure. According to the Mayo Clinic, if you suspect an E. coli infection, it’s critical to seek medical attention immediately.
What to Do If You’ve Eaten a Quarter Pounder
If you’ve consumed a Quarter Pounder from McDonald’s in one of the affected states within the past week and are experiencing symptoms like those listed above, the FDA advises contacting a healthcare provider immediately. Be sure to inform them:
- What you ate
- When you ate it
- Which McDonald’s location you visited, if known
If you still have the burger in your possession, it’s best to safely discard it rather than risk consuming it.
Ongoing Investigation and Next Steps
As of now, the investigation is still in its early stages. Both the FDA and FSIS are conducting thorough traceback investigations on the slivered onions and fresh beef patties used in the Quarter Pounders to pinpoint the exact source of contamination. While the slivered onions are considered a likely suspect, no single ingredient has been definitively confirmed.
McDonald’s has committed to keeping the public updated as the investigation continues. The company is also working closely with authorities to address the outbreak and ensure that all affected products are removed from restaurants.
What Precautions Can You Take?
Although the outbreak has been linked to specific McDonald’s items, foodborne illnesses can arise from a variety of sources. Here are some precautions to minimize the risk of contracting E. coli or other bacterial infections:
- Wash your hands thoroughly before handling food.
- Cook beef to a safe temperature of 160°F to kill harmful bacteria.
- Avoid cross-contamination by keeping raw meat separate from other foods.
- Wash fruits and vegetables thoroughly before eating.
- Store food at the proper temperature to prevent bacterial growth.
Conclusion:
While the news of this E. coli outbreak is concerning, it’s important to remember that the investigation is still developing. McDonald’s is taking action by removing potential sources of contamination from its menu, and federal agencies are working to trace the origins of the outbreak.
In the meantime, consumers in the affected states should stay vigilant and seek medical advice if they feel ill after eating a Quarter Pounder.
Stay tuned for updates from the FDA, CDC, and McDonald’s as more information becomes available. For now, if you’re in one of the affected states, it’s best to avoid Quarter Pounders until the investigation concludes.
