As of October 30, 2024, an ongoing investigation reveals a significant outbreak of E. coli O157:H7 infections connected to fresh slivered onions served in McDonald’s Quarter Pounder hamburgers. The investigation began on October 22, 2024, and the current status indicates that immediate action has been taken to address the issue through product recalls and food service modifications.

The Centers for Disease Control and Prevention (CDC) notes an increase in illness reports linked to these onions prior to their removal from restaurants; however, due to swift actions from both McDonald’s and Taylor Farms—who supplied these onions—the CDC now assesses the risk for further public health impact as minimal.
Investigation Details
Public health authorities including the CDC, FDA, USDA-FSIS are probing this outbreak where many affected individuals reported consuming Quarter Pounders with slivered onions shortly before falling ill. To mitigate further spread of infection, McDonald’s has ceased using slivered onions across various states while scientists trace epidemiological links back to specific food sources.
Source Identification
Evidence collected during this investigation points toward contaminated fresh slivered onions as the primary source contributing to illnesses among consumers. Taylor Farms has acted swiftly by issuing a recall for yellow onions distributed particularly within food service sectors—including numerous restaurants—effectively minimizing public access to these potentially hazardous foods.
Recall Information
Concerns regarding safety have led McDonald’s to withdraw both fresh slivered onions and quarter pound beef patties pending a definitive identification of contaminated ingredients—which now appears focused on onion use.
Food service establishments received direct notification from Taylor Farms instructing them not only against serving recalled products but also advising caution concerning remaining onion supplies in storage or stock.
Recommendations for Consumers
Given that all problematic products have been recalled and removed from circulation within food services:
- There is no need for consumers to avoid other varieties or forms of onion currently available.
- Individuals experiencing severe symptoms commonly associated with E. coli infections should seek prompt medical attention if they notice any concerning signs such as:
– Severe diarrhea accompanied by fever exceeding (102°F)
– Persistent diarrhea lasting beyond three days without substantial improvement
– Presence of blood in stool samples
– Excessive vomiting preventing fluid retention
Potential indicators depleting hydration include infrequent urination coupled with dry mucous membranes or dizziness upon standing up—noting that timely intervention is crucial when presented with such symptoms.
Precautions for Businesses
Restaurants and other food service operators must refrain from serving or selling any yellow onions implicated in Taylor Farms’ recall directive while cooperating fully with hygiene protocols established by health departments at local state levels.
Understanding E. Coli Symptoms
Individuals infected by Shiga toxin-producing E.coli may report severe abdominal pains alongside otherwise uncontrollable diarrhea—often bloody—and nausea resulting in frequent episodes of vomiting typically surfacing between three-to-four days post-ingestion. Most recover without clinical support after approximately five-to-seven days; nonetheless, some might develop further complications leading potentially towards hospitalization due primarily either systemic shock conditions like hemolytic uremic syndrome (HUS).
