The recent E. coli outbreak tied to select McDonald's items has now spread to 13 states with a current total of 75 reported cases. As per the NBC Chicago report, health officials have linked the serious string of illnesses primarily to slivered onions served on Quarter Pounders. The escalation of cases, up from an initial report of 49, has prompted an intensive investigation by the Centers for Disease Control and Prevention (CDC).
The CDC's update, released on Friday, has brought to attention new cases emerging in states that were not previously implicated. The latest information, as conveyed by Business Insider, illuminates Michigan, New Mexico, and Washington as the most recent additions to a growing list. Colorado remains the hardest hit, shouldering 26 of the total cases. The cross-state nature of the outbreak was highlighted by at least one individual contracting the illness from a McDonald’s located outside their home state.
Out of the 61 detailed cases at the CDC's disposal, 22 have led to hospitalizations, with one resulting in death—an older adult from Colorado. Officials are warning that these numbers could well be underreported. Infections sometimes resolve without medical testing, and there is typically a three to four-week delay in confirming whether new cases tie back to this specific outbreak. While initial suspicions revolved around Quarter Pounder beef patties, further scrutiny has shifted the focus squarely onto the slivered onions.
In a briefing to the public, McDonald's representatives leaned towards identifying contaminated ingredients—likely slivered onions—as the root cause of the outbreak, implying it to be a supply issue rather than the result of in-house food handling or preparation processes. In response, Taylor Farms, the regional provider of these onions for McDonald’s, has already initiated a recall. This precaution has subsequently affected several other brands, with fast food chains like Burger King and Taco Bell opting to tentatively remove onions from their menu offerings in specific outlets.
The issue has rippled through the supply chain, leading distributor U.S. Foods to recall four raw onion products "out of an abundance of caution because of potential E. coli contamination," as noted by the NBC Chicago article. Amidst investigations, McDonald's has pulled the suspected product from affected locales and temporarily ceased offering Quarter Pounder burgers in those regions. This measure stands as an interim effort to mitigate any further spread of the E. coli bacteria pending full clarity on the outbreak's source.
