The Scope of the E. coli Outbreak
As of October 2024, a total of 49 cases of the E. coli outbreak have been reported across 10 states, with 10 hospitalizations and one death. Most of the illnesses are concentrated in Colorado and Nebraska. The CDC and other health agencies are investigating the cause, but preliminary findings suggest that slivered onions used in Quarter Pounders E. Coli could be a likely source of contamination. However, the exact ingredient causing the McDonald’s E. Coli outbreak is still under review.

What is E. Coli and E. Coli Symtomps ?
Escherichia coli (E. coli) is a bacterium commonly found in the intestines of people and animals. While most strains are harmless, some can cause serious gastrointestinal illness. The strain linked to the McDonald’s outbreak, E. coli O157, produces Shiga toxin, which can lead to severe illness.
Common E. Coli Symptoms
Individuals infected with E. coli may experience symptoms such as:
- Severe stomach cramps
- Diarrhea (often bloody)
- Vomiting
- Fever higher than 102°F or 38.89 °C in severe cases
Symptoms usually begin three to four days after consuming the contaminated food and can last up to a week. While most people recover without treatment, some may develop hemolytic uremic syndrome (HUS), a serious complication that affects the kidneys and requires hospitalization.
When to Seek Medical Attention
Anyone who has eaten a McDonald’s Quarter Pounder and experiences severe symptoms should contact their healthcare provider immediately. Seek urgent care if you have:
- Diarrhea lasting more than three days
- Bloody diarrhea
- Vomiting to the point where you cannot keep liquids down
- Signs of dehydration (e.g., dry mouth, infrequent urination, or dizziness)
McDonald’s Quarter Pounder E. Coli Outbreak: What You Can Do
While McDonald’s has taken steps to remove the potentially contaminated ingredients from its menu in certain areas, consumers should remain vigilant. If you’ve eaten a Quarter Pounder E. Coli recently and are experiencing E. coli symptoms, it is important to seek medical care and inform your healthcare provider about what you ate.
For now, McDonald’s is working to replenish the supply of Quarter Pounders in unaffected areas, and they will provide updates as more information becomes available.
McDonald’s said in a press-release statement that Quarter Pounders E. coli have been pulled from McDonald’s chains across the following states:
- Colorado
- Kansas
- Utah
- Wyoming
It has also been removed in portions of:
- Idaho
- Iowa
- Missouri
- Montana
- Nebraska

The E. coli outbreak linked to McDonald’s Quarter Pounder hamburgers is a serious concern, with multiple illnesses and one confirmed death. As the investigation unfolds, McDonald’s has pulled Quarter Pounder patties and slivered onions in several states as a precaution. Consumers are encouraged to monitor for symptoms and seek medical attention if necessary.
