The agency has not identified a common grower, supplier, distributor or brand. But officials advise that consumers, restaurants and retailers should throw out any romaine lettuce that came from the Yuma area, even if some of it was eaten and no one has gotten sick.
Symptoms of E. coli infection include diarrhea, severe stomach cramps and vomiting. Most people recover within one week, but some illnesses last longer and can be more severe, resulting in a type of kidney failure.
