WASHINGTON -- Contaminated California-grown lettuce was the possible source of the E. coli outbreak that sickened more than 80 people late last year at Taco John's restaurants in two states, health officials said Friday.
State and federal investigators said they have matched the strain of the bacteria associated with the outbreak to two samples taken from dairy farms in California's Central Valley. The farms are located near lettuce fields, the Food and Drug Administration said.
