Wendy’s cuts out lettuce from sandwiches in 3 states after illnesses

Wendy’s has removed lettuce from sandwiches it serves in the states of Michigan, Ohio, and Pennsylvania after an E. coli contamination sickened at least 37 people.

The illness in the three states has been tied to a romaine-iceberg hybrid that is unique to Wendy’s, and that it uses only on sandwiches.

The illnesses have included severe pain, bloody diarrhea, and bloating.

Federal authorities have not yet advised consumers to avoid Wendy's. However, as a voluntary measure, the quick-service restaurant chain announced this week that it will no longer offer lettuce on sandwiches.

The lettuce implicated in the outbreak comes from a single supplier.
