"The outbreak is continuing," the USDA says in a public health alert naming three facilities operated by Foster Farms as the likely source of raw chicken contaminated with a strain of bacteria known as salmonella Heidelberg. Most of the chicken has been sold in California, Oregon and Washington, and most of the illnesses have occurred in California, USDA says.

 

But no recall has been announced and the agency's Food Safety and Inspection Service "is unable to link the illnesses to a specific product and a specific production period," the news release says.
