CDC collaborated with public health officials in multiple states and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella Enteritidis infections which was associated with eating food from a Mexican-style fast food restaurant chain, Restaurant Chain A. Investigative efforts were unable to identify a specific food associated with illness, but data indicate that contamination likely occurred before the product reached Restaurant Chain A locations.
A widely distributed contaminated food product might cause illnesses in a specific region and across the United States. As of January 19, 2012, a total of 68 individuals infected with the outbreak strain of Salmonella Enteritidis have been reported from 10 states. The number of ill persons identified in each state with the outbreak strain was as follows: Texas (43), Oklahoma (16), Kansas (2), Iowa (1), Michigan (1), Missouri (1), Nebraska (1), New Mexico (1), Ohio (1), and Tennessee (1).
