2011 Salmonella Enteritidis at Taco Bell Restaurant Chain

A multistate outbreak of Salmonella Enteritidis was reported by the Centers for Disease Control on January 19, 2012. The outbreak was associated with eating at an unnamed Mexican style fast food chain beginning in October, 2011. No specific food was epidemiologically associated with illness, but data suggested that contamination of the food occurred before it had reached the chain's outlets. Among ill persons eating at the restaurant chain, 90% reported eating lettuce, 94% reported eating ground beef, 77% reported eating cheese, and 35% reported eating tomatoes. The epidemic curve seen in the outbreak was consistent with those observed in past produce outbreaks with a sharp increase and decline of ill persons that spanned one to two months. Ground beef was thought to be an unlikely source due to the handling and cooking processes used by restaurant chain. The Centers for Disease Control and Prevention declined to name the restaurant chain in the outbreak, however on February 1, Food Safety News, reported that the outbreak involved Taco Bell restaurants. An investigation summary from the Oklahoma State Department of Health linked the state's 16 cases to the Taco Bell restaurant chain. The outbreak was given the cluster identification code of: 1111TXJEG-1.
