Foster Farms Salmonella outbreak causes serious concern
CDC cites 278 cases – 213 cases from California alone
CDC is collaborating with public health and agriculture officials in many states and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS) to investigate a multistate outbreak of Salmonella Heidelberg infections. Public health investigators are using DNA “fingerprints” of Salmonella bacteria obtained through diagnostic testing with pulsed-field gel electrophoresis, or PFGE, to identify cases of illness that may be part of this outbreak. They are using data from PulseNet, the national subtyping network made up of state and local public health laboratories and federal food regulatory laboratories that performs molecular surveillance of foodborne infections. Seven strains of Salmonella Heidelberg bacteria have been identified as being linked to this outbreak. Four of these strains are rarely reported to PulseNet. The other three strains are more common, with several ill persons infected with each strain reported to CDC monthly. The DNA fingerprints of the Salmonella Heidelberg bacteria associated with the current outbreak include the strain that was also associated with a multistate outbreak of Salmonella Heidelberg linked to Foster Farms brand chicken during 2012-2013.
As of October 7, 2013, a total of 278 individuals infected with the outbreak strains of Salmonella Heidelberg have been reported from 17 states. Most of the ill persons (77%) have been reported from California. The number of ill persons identified in each state is as follows: Alaska (2), Arkansas (1), Arizona (11), California (213), Colorado (4), Connecticut (1), Florida (1), Hawaii (1), Idaho (2), Michigan (2), North Carolina (1), Nevada (8), Oregon (8), Texas (5), Utah (2), Washington (15) and Wisconsin (1).
Among 274 persons for whom information is available, illness onset dates range from March 1 to September 24, 2013. Ill persons range in age from 1 year to 93 years, with a median age of 20 years. Fifty-one percent of ill persons are male. Among 183 persons with available information, 76 (42%) reported being hospitalized. No deaths have been reported.
Illnesses that occurred after September 1, 2013 might not be reported yet due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 3 weeks. For more details, please see Salmonella Outbreak Investigations: Timeline for Reporting Cases.
