A report by food safety investigators have linked a Kern County farm with an E. coli outbreak in 2006 that sickened dozens of people in the Midwest. Officials from the California Department of Health and the Food and Drug Administration reported that tainted lettuce served at Taco John’s restaurants in Iowa and Minnesota came from Wegis Ranch in Buttonwillow. More than 80 people became sick with E. coli infections after eating the lettuce. Investigators said they found positive samples of E. coli at Wegis Ranch and at two neighboring dairies.
