The US Centers for Disease Control and Prevention has announced that romaine lettuce was the source of the E. coli outbreak that sickened a total of 60 people in ten states earlier this fall.
Thirty-seven of those infected were in Missouri.
On its website, the CDC says the lettuce came from salad bars from a single grocery store chain but did not report the name of the chain. Schnucks management has confirmed that it is the chain in question.
