E. coli Outbreak Linked to McDonald’s Quarter Pounders: State-by-State Breakdown

October 23, 2024   1073

Overview of the Outbreak

Between September 27 and October 11, 2024, an outbreak of E. coli O157

has affected several states, with cases ranging from Colorado (26 cases) to Wyoming (1 case). Patients’ ages span 13 to 88 years, with 10 hospitalizations reported, reflecting a high hospitalization rate of 36%. Sadly, one older adult from Colorado succumbed to the illness, though they did not develop hemolytic uremic syndrome (HUS).

Investigation and Response

Preliminary investigations suggest slivered onions or beef patties used in Quarter Pounders may be the source. The FDA continues its traceback efforts, with early indications pointing to onions. McDonald’s has removed these ingredients from several locations as a precaution until the investigation is complete.

Interviews with 18 patients revealed that all had eaten at McDonald’s, and 86% consumed Quarter Pounders. The outbreak's wide distribution suggests that some individuals traveled across state lines before falling ill.

Symptoms and What to Do if Infected with E. coli O157

Symptoms:

  • Severe abdominal cramps
  • Bloody diarrhea
  • Nausea and vomiting
  • Fever (not always present)

Complications:
In some cases, E. coli O157

can cause hemolytic uremic syndrome (HUS), which leads to kidney failure. Symptoms of HUS include reduced urine output, fatigue, bruising, and nosebleeds.

What to Do:

  1. Seek Immediate Medical Care: If symptoms like bloody diarrhea or severe cramps occur.
  2. Stay Hydrated: Drink fluids to prevent dehydration.
  3. Avoid Anti-Diarrheal Medications: They can worsen the condition.
  4. Monitor Children Closely: HUS primarily affects kids under 5 years old.

Expert Commentary

Anna Klyauzova, Director of Patient Services, emphasizes that outbreaks like this highlight the critical need for strict food safety practices throughout the supply chain. "No one should face severe illness, or worse, because of a simple meal choice," she says. She points out that ingredients like onions have previously been involved in similar outbreaks, underscoring the importance of proactive safety checks. Anna urges individuals experiencing symptoms to seek medical attention promptly, especially given the risks of HUS, which can lead to severe complications, particularly in children.

CDC's Latest Findings and Investigation Progress

As of October 22, 2024, the CDC confirms that the outbreak has impacted 10 states, with the most cases reported in Colorado (26 cases), followed by Nebraska (9 cases) and Utah (4 cases). Traceback investigations are focusing on slivered onions and beef patties used in Quarter Pounders as likely sources of contamination. McDonald’s has removed these ingredients from affected locations pending further investigation. The CDC advises anyone experiencing E. coli symptoms, such as fever, cramps, and bloody diarrhea, to seek immediate medical attention (CDC, 2024; Food Safety News, 2024).
