Fast-food chain Wendy’s is withdrawing romaine lettuce from sandwiches at its restaurants in Michigan, Ohio and Pennsylvania after some people reported getting sick.
The Centers for Disease Control and Prevention (CDC) said Friday that it is trying to determine whether romaine lettuce is the source of an E. coli outbreak that has infected at least 37 people and whether romaine lettuce used at Wendy’s was also served or sold at other establishments.
According to the CDC, one person also became ill in Indiana. A message was left at Wendy’s about lettuce in sandwiches in that state.
According to the CDC, there is no evidence that romaine lettuce sold in grocery stores is linked to the E. coli outbreak. Nor does the agency recommend stopping eating at Wendy’s or not eating romaine lettuce.
Wendy’s states that the lettuce used in its salads is different and is not affected by the decision to remove lettuce from sandwiches. The company said it is cooperating with the CDC.
“As a company, we are committed to maintaining our high food safety and quality standards,” Wendy’s said in a statement.
