Federal health officials have yet to pinpoint the exact source of the contamination. However, the U.S. Food and Drug Administration (FDA) reported that their investigation focuses on slivered onions and beef patties used in the burgers. According to CNN, McDonald’s identified Taylor Farms, a California-based produce supplier, as the source of the potentially contaminated yellow onions. Consequently, McDonald’s has recalled these onions and removed Quarter Pounders from menus in affected states.
- Contamination Source Under Investigation: The FDA’s investigation into an E. coli outbreak focuses on slivered onions and beef patties, particularly yellow onions sourced from Taylor Farms, a supplier for McDonald’s.
- Industry-Wide Precautions: McDonald’s, along with other major chains like Taco Bell and Burger King, temporarily removed onions from their menus to minimize potential risk.
- E. Coli Health Risks: Symptoms of E. coli infection appear within 1-2 days, including fever, vomiting, and dehydration, with vulnerable groups like young children and the elderly facing higher risks.
- Lawsuit Filed: A Colorado man filed a lawsuit against McDonald’s, claiming he contracted E. coli from contaminated food, adding urgency to the ongoing investigation.
The recall has prompted other fast-food chains, including Taco Bell, Pizza Hut, KFC, and Burger King, to temporarily remove onions from their menus. These measures were taken as a precautionary response to the outbreak. McDonald’s decision to recall the onions came after Taylor Farms issued a recall for peeled and diced yellow onions due to potential E. coli contamination. However, U.S. Foods, a significant wholesaler, stated they were not a supplier to McDonald’s and their recall did not involve products sold at the fast-food chain.
The FDA has yet to confirm if Taylor Farms is solely responsible for the outbreak. Their spokesperson mentioned that the agency is considering all possible sources. In the past, onions have been implicated in similar outbreaks. In 2015, Taylor Farms recalled a celery and onion mix after a related E. coli outbreak. Last year, an outbreak of salmonella linked to onions from Gills Onions resulted in 80 illnesses and one death.
Symptoms of E. coli infection can appear quickly, typically within one to two days after consuming contaminated food. Common symptoms include fever, vomiting, diarrhea, and dehydration. The infection poses a higher risk to children under five, the elderly, pregnant individuals, and those with weakened immune systems. If experiencing symptoms, individuals should seek medical attention promptly.
In response to the outbreak, a lawsuit has been filed against McDonald’s by a man from Greeley, Colorado. Eric Stelly claims he contracted E. coli after consuming food from a local McDonald’s. His infection was confirmed as part of the outbreak following emergency medical care.
As the investigation continues, the CDC and FDA urge consumers to exercise caution and avoid consuming contaminated products. They recommend monitoring recall notices and adhering to guidelines from health officials to prevent further illness.
