Case Count Update

As of July 2, 2014, a total of 621 individuals infected with the outbreak strains ofSalmonella Heidelberg have been reported from 29 states and Puerto Rico since March 1, 2013. Most of the ill persons (77%) have been reported from California. Since the last update on May 27, 2014, a total of 47 additional ill persons have been reported from 5 states: Alabama (1), California (39), Oregon (3), Washington (3), and West Virginia (1). Fifteen (32%) of these additional ill persons have illness onset dates in June. During this time of year, approximately 3 to 5 illnesses with the outbreak strains would be expected each week; recently, 6 to 9 illnesses have occurred each week.
Among 608 persons for whom information is available, illness onset dates range from March 1, 2013 to June 15, 2014. Ill persons range in age from younger than 1 year to 93 years, with a median age of 18 years. Fifty percent of ill persons are male. Among 504 persons with available information, 181 (36%) reported being hospitalized. Thirteen percent of ill persons have developed blood infections as a result of their illness. Typically, approximately 5% of persons ill with Salmonella infections develop blood infections. No deaths have been reported.
This outbreak investigation is ongoing; however, since an increase in illnesses noted in February and March, there has been a decline in the weekly number of illnesses occurring. The number of illnesses is now approaching the expected number for this time of year.  Illnesses that began after June 2, 2014, 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 4 weeks.

Investigation Update

On July 3, 2014, Foster Farms recalledExternal Web Site Icon an undetermined amount of chicken products that may be contaminated with a particular strain of Salmonella Heidelberg. The recall resulted from USDA-FSIS identifying one of the outbreak strains of SalmonellaHeidelberg in an intact sample of Foster Farms brand chicken collected from the home of a person infected with the same strain in California. The chicken breasts were packaged with critical labeling information to associate the product with the establishment and a specific production date.  The ill person’s family purchased their chicken in March; however, it was stored in the family’s freezer and consumed in late April. Although the recalled chicken has production dates of March 7 through March 13, 2014, USDA-FSIS and CDC are concerned that the recalled chicken could still be in people’s freezers. Consumers should check their freezers for the recalled chicken and should not eat it.
