Update: 84 People Sickened in E. coli Outbreak Linked to Wendy's Lettuce

An ongoing E. coli outbreak has resulted in 84 confirmed cases across four states, with health authorities linking this infection to contaminated lettuce used in Wendy's restaurant sandwiches. The outbreak, which has been under investigation since early reports, has led to significant health concerns, especially given the severity of some cases.

Since August 19, 2022, an additional 47 illnesses have been reported to the CDC, bringing the total to 84. These cases are distributed as follows: 53 in Michigan, 23 in Ohio, 6 in Indiana, and 2 in Pennsylvania. Severe symptoms have been observed, including hospitalization of 38 affected individuals. Notably, eight people in Michigan developed hemolytic uremic syndrome (HUS), a dangerous form of kidney failure caused by the E. coli bacteria. Fortunately, no fatalities have been reported so far.

While the precise source of the outbreak remains unconfirmed, a strong link has been established between the illnesses and the consumption of Wendy’s sandwiches that contain romaine lettuce. In detailed interviews, 88% of affected individuals who provided specific food data reported eating romaine lettuce on their sandwiches. Wendy’s responded promptly by removing romaine lettuce from its sandwiches in the impacted regions, such as Michigan, Ohio, and Pennsylvania, as a precautionary measure.

The CDC clarifies that grocery-store romaine lettuce does not appear to be affected, and consumers can continue eating salads at Wendy’s that use different kinds of lettuce. Wendy’s also confirmed that their salad lettuce is sourced separately from the variety used in sandwiches.

E. coli infections typically manifest 3 to 4 days after exposure but can range from 1 to 10 days. Symptoms usually last for 5 to 7 days and include diarrhea, abdominal cramps, fever, vomiting, and sometimes blood in the stool. Severe cases require immediate medical attention, especially if symptoms such as prolonged diarrhea, high fever, or signs of kidney failure occur.

Health authorities advise individuals to monitor for serious symptoms and report any illnesses consistent with E. coli infection to healthcare providers and local health departments. Maintaining good hygiene and proper food handling practices remain crucial in preventing such outbreaks.
