Romaine Lettuce

The CDC's message is clear: Do not eat any romaine lettuce. And if you have any in your kitchen, get rid of it. Romaine from Arizona is contaminated with E. coli, which can lead to diarrhea, vomiting and in some cases, hospitalization and death. So since you can't know where your lettuce was grown, take no chances and skip the Caesar salad until this blows over.
