2003 Outbreak of E. coli O157:H7 Linked to Pat & Oscar's Restaurants, California

The San Diego County Health Department began investigating multiple cases of E.coli O157:H7. The investigation revealed that pre-mixed, packaged lettuce was implicated in the illnesses. These lettuce mixes were used by various outlets of the Pat & Oscar's restaurant chain. Three children from three school districts also became ill. At least 13 school districts received the lettuces mixes for the school lunch programs. Traceback and environmental investigations implicated a “70/30 lettuce mix” and a “4-way-bite-size” lettuce mix manufactured by Gold Coast Produce (GCP), an unregistered food processor, in Oxnard, California. Iceberg lettuce and romaine were the only common ingredients in the 70/30 lettuce mix and the 4-way-bit-size lettuce mix.
