2001 Outbreak of E. coli O157:H7 at a College Dining Hall, Washington

Eating whole pears that had been served at a college dining facility, in Washington state, was associated with a risk of E. coli O157:H7 infection. A traceback of the pears showed no evidence of fecal contamination in the orchard. A food worker source for this outbreak was likely. The food worker was the index case and had served the pears, and other foods, bare handed while he had been ill with diarrhea. Blood tests confirmed that the food worker recently had an E. coli O157:H7 infection.
