At the request of the federal government, Crescent Speciality Foods Inc. is recalling raw pistachios because of possible contamination with Salmonella.

The Everett, WA, company distributed the to retail stores and online stores in Oregon and Washington state from Oct. 21, 2015 through May 2 this year. No illnesses had been confirmed in relation to the recalled nuts as of the posting of the recall notice. The recalled product, packaged in 6-ounce plastic bags, can be identified by the UPC number 8 95296 00103 5 on the label. The label has a photograph of mixed fruits and nuts, but the recalled packages contain only pistachio nuts. “The recall was as a result of a routine, random sampling program conducted by an FDA third-party contracted lab which revealed the recalled product tested positive for Salmonella. The root cause is unknown to date,” according to the recall notice on the Food and Drug Administration’s website. “This recall is being made at the request of the U.S. Food and Drug Administration. Consumers should not consume the product. The consumer should return the product to place of purchase for a refund. Customers with questions may contact the stores where they purchased the product. For further inquiries email (the company) at: info@csf1.com.” Anyone who has eaten the recalled pistachios and developed symptoms of Salmonella infection should seek medical attention and be tested. Salmonella is a microscopic organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems, according to the FDA and the Centers for Disease Control and Prevention. Healthy people infected with Salmonella often experience fever, diarrhea that may be bloody, nausea, vomiting and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections including infected aneurysms, endocarditis and arthritis.
