Federal Health Officials Conclude Investigation into E. coli Outbreak Linked to Contaminated Onions
Background
In October, a multi-state E. coli outbreak was identified, affecting 104 people across 14 states, resulting in 34 hospitalizations and one death. The Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) launched an investigation to determine the source of the outbreak.
Investigation Findings
The investigation revealed that the outbreak was linked to yellow onions distributed by Taylor Farms, which issued a voluntary recall of the contaminated onions. McDonald’s, which had served the affected onions on their Quarter Pounder burgers, immediately removed the recalled product from their restaurants in affected states and sourced an alternative supply of slivered onions for hundreds of its restaurants.
CDC and FDA Confirm Closure of Investigation
The CDC and FDA have now concluded their investigations, and officials have confirmed that the risk to the public is "very low." McDonald’s officials have also released a statement, saying that the CDC and FDA have confirmed the closure of their investigations, and that the risk to the public has remained very low since then.
E. coli Symptoms and Prevention
E. coli symptoms can range from severe stomach cramps and diarrhea to life-threatening complications like kidney failure. Federal and state officials emphasize the importance of food service providers following safe handling and cleaning practices to prevent cross-contamination.
Additional Information
While additional tests on the recalled onions did not detect the specific outbreak strain, evidence pointed to the yellow onions as the likely source. The CDC confirmed that there have been no new illnesses linked to McDonald’s following their actions in October. Restaurants that may have purchased the contaminated onions were urged not to serve them and to throw out any frozen supplies. The FDA stated that it is unlikely any contaminated onions were sold to grocery stores or directly to consumers.
Conclusion
The investigation has concluded that the E. coli outbreak was linked to contaminated yellow onions distributed by Taylor Farms and served on McDonald’s Quarter Pounder burgers. While the risk to the public is now considered very low, it is essential for food service providers to prioritize safe handling and cleaning practices to prevent cross-contamination and ensure public health.
