Escherichia coli O157 : H7 infections have traditionally been associated with animal products, but outbreaks associated with produce have been reported with increasing frequency.
In fall 1996, a small cluster of E. coli O157 : H7 infections was epidemiologically linked to a particular brand (brand A) of unpasteurized apple juice.
To define the extent of the outbreak, confirm the source, and determine how the apple juice became contaminated.
Descriptive epidemiologic study and traceback investigation.
Western United States and British Columbia, Canada.
Patients with E. coli O157 : H7 infection who were exposed to brand A apple juice.
Clinical outcome and juice exposure histories of case-patients, pulsed-field gel electrophoresis of case and juice isolates, and juice production practices.
Seventy persons with E. coli 0157 : H7 infection and exposure to brand A unpasteurized apple juice were identified.
Of these persons, 25 (36%) were hospitalized, 14 (20%) developed the hemolytic uremic syndrome, and 1 (1%) died.
Recalled apple juice that was produced on 7 October 1996 grew E. coli O157 : H7 with a pulsed-field gel electrophoresis pattern indistinguishable from that of case isolates.
Apple juice produced on 7 October 1996 accounted for almost all of the cases, and the source of contamination was suspected to be incoming apples. (...)
