According to the CDC today the investigation continues into Salmonella Heidelberg infections likely related to Foster Farms chicken.
The number of reported infections from all seven outbreak strains of Salmonella Heidelberg returned to baseline levels in January and the outbreak appeared to be over, as noted in the previous update on January 16, 2014. However, the investigation continued.
Ongoing surveillance identified in February that infections from two of the previously rare outbreak strains have again exceeded the number of infections expected to be reported to PulseNet during this time of year.
Epidemiologic, laboratory, and traceback investigations conducted by local, state, and federal officials indicate that consumption of Foster Farms brand chicken is the likely source of this outbreak of Salmonella Heidelberg infections.
