The CDC announced today a total of 634 persons infected with seven outbreak strains of Salmonella Heidelberg were reported from 29 states and Puerto Rico from March 1, 2013 to July 11, 2014.

38% of ill persons were hospitalized, and no deaths were reported.

Most ill persons (77%) were reported from California.

The current outbreak appears to be over as the number of reported infections has returned to the expected number for this time of year.

Epidemiologic, laboratory, and traceback investigations conducted by local, state, and federal officials indicated that consumption of Foster Farms brand chicken was the source of this outbreak of Salmonella Heidelberg infections.
