Abstract
Escherichia coli O157 is an important serotype of en-terohemorrhagic E. coli that causes hemorrhagic colitis worldwide. Outbreaks of E. coli O157 have been assocoated with contaminated food like meat, raw milk, and water, but recently vegetables and fruits have accounted for a growing number of recognized outbreaks. We isolated verotoxin producing E. coli O157 from the stool of a 3 year-old female with bloody diarrhea and abdominal pain. The child had been eating salad with vegetables and fruits frequ-ently.
