FDA is using all available tools to confirm if onions are the source of this outbreak. This includes working with federal and state partners and the companies involved to collect and evaluate records and distribution information as part of our traceback investigation. FDA and state partners are also collecting onion samples for analysis.
While the investigation is ongoing, Taylor Farms, the supplier of slivered onions for the affected McDonald’s locations, has initiated a voluntary recall. Recalled yellow onions were sold to additional food service customers. Customers who received recalled onions have been directly notified of the recall.
FDA is working closely with the implicated firms and will continue to provide updates as they become available, including any additional recalls or notifications that might be needed for recipients of recalled onions.
At this time, FDA is not aware of any cases or affected product outside of the United States.
