2006 Outbreak of E. coli O157:H7 at Taco John's Restaurants Linked to Iceberg Lettuce

Iowa and Minnesota health officials investigated an E.coli O157:H7 outbreak among patrons at Taco John's restaurants in Iowa(Cedar Falls) and Minnesota (Albert Lea and Austin). Although this outbreak occurred at the same time as the Taco Bell E.coli outbreak on the East Coast, the Taco John outbreak was not linked with the outbreak at Taco Bell. Shredded iceberg lettuce that was served in the restaurants was determined to be the likely vehicle of transmission. The outbreak strain matched environmental samples gathered from dairy farms near a lettuce growing area in California's Central Valley.
