The Centers for Disease Control and Prevention (CDC) has issued an updated Food Safety Alert concerning a recent outbreak of E. coli infections, traced back to fresh, slivered onions served at McDonald’s. This update follows epidemiologic and traceback data that have identified these onions as the potential source of the outbreak. As of October 30, 2024, the outbreak has expanded with 15 new cases, raising the total number of infections to 90. Furthermore, there have been five additional hospitalizations, bringing that total to 27.
The most recent onset of illness occurred on October 16, 2024. Importantly, these cases developed before McDonald's, in collaboration with Taylor Farms, undertook measures to remove the implicated onions from all food service locations. Due to these swift actions, the CDC assesses that the ongoing risk to the public is very low.
Consumers are advised that if they experience severe symptoms of E. coli infection, such as intense stomach cramps, bloody diarrhea, or vomiting, they should seek medical attention and report their recent food history to their healthcare provider. Businesses are cautioned against using onions supplied by Taylor Farms that have been subject to recall.
Typical symptoms of Shiga toxin-producing E. coli involve acute stomach discomfort, diarrhea, and vomiting, manifesting about 3 to 4 days post-exposure. While recovery often ensues within a week without medical intervention, some individuals may face severe kidney complications, known as hemolytic uremic syndrome (HUS), necessitating hospitalization.
For individuals seeking more detailed information regarding E. coli, or for inquiries about affected states, contacting local health departments is recommended. The CDC continues to monitor the situation closely and remains at the service of the public for further information and updates.
