The FDA and the California Department of Public Health (CDPH) are investigating Salmonella contamination in pistachio products sold by Setton Pistachio of Terra Bella Inc, Calif. The company has stopped all distribution of processed pistachios and will issue a voluntary recall involving approximately 1 million pounds of its products. Because the pistachios were used as ingredients in a variety of foods, it is likely this recall will impact many products. In addition, the investigation at the company is ongoing and may lead to additional pistachio product recalls.

The contamination involves multiple strains of Salmonella. Salmonella can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Thus far, several illnesses have been reported by consumers that may be associated with the pistachios. It is not yet known whether any of the Salmonella strains found in the pistachio products are linked to an outbreak. The FDA is conducting genetic testing of the samples to pursue all links.
