Beginning in April, 197 people across 35 states contracted E. coli believed to have originated in Yuma, Arizona. Most of the victims reported eating bagged, pre-cut romaine lettuce, although some were merely in close contact with those who became sick from consuming it. Of the 197 victims, 89 required hospitalization.
