(8-21-22) A specific food has not yet been confirmed as the source of this outbreak, but many sick people reported eating sandwiches with romaine lettuce at Wendy’s restaurants in Michigan, Ohio and Pennsylvania before getting sick. Based on this information, Wendy’s is taking the precautionary measure of removing the romaine lettuce being used in sandwiches from restaurants in that region. Wendy’s uses a different type of romaine lettuce for salads. Investigators are working to confirm whether romaine lettuce is the source of this outbreak, and whether romaine lettuce used in Wendy’s sandwiches was served or sold at other businesses. Wendy’s is fully cooperating with the investigation.
The Centers for Disease Control (CDC) is currently investigating a multi-state, fast moving outbreak of E. coli strain O157.
CDC is not advising that people avoid eating at Wendy’s restaurants or that people stop eating romaine lettuce.
