Wendy’s pulls lettuce from sandwiches in three states amid E coli outbreak

CDC is trying to determine whether romaine lettuce is the source of an outbreak that has sickened 37 people

The fast-food chain Wendy's says it is pulling lettuce from sandwiches in its restaurants in Michigan, Ohio and Pennsylvania after people eating them there reported falling ill.

The US Centers for Disease Control and Prevention (CDC) said Friday it is trying to determine whether romaine lettuce in Wendy's sandwiches is the source of an E coli outbreak that has sickened over 30 people - and whether romaine used by the chain was also served or sold at other businesses.
