COMMACK, N.Y. — Setton International Foods, Inc., the parent company of Setton Pistachio of Terra Bella, Inc. in California, has initiated a recall of nut products that may contain pistachios manufactured by the company’s Terra Bella facility. The recall is not connected to recent inspections of the Setton’s New York facility conducted by New York state officials and the Food and Drug Administration, according to the company.

The F.D.A. said the product contamination involves several strains of Salmonella. To date, several illnesses have been reported that the agency said may be associated with pistachio consumption. It is not yet known whether any of the Salmonella strains found in the pistachio products are linked to a specific foodborne illness outbreak. The F.D.A. is conducting genetic testing of the samples.

The F.D.A. learned of the problem on March 24 when it was informed by Kraft Foods Inc. that its Back to Nature brand of trail mix was found to be contaminated with Salmonella. Kraft identified the source of the contamination to be pistachios from Setton and initiated a recall of its products.

Since March 30, in addition to Setton and Kraft Foods, several other companies, including Frito-Lay, Kroger Co., John B. Sanfilippo, Publix Supermarkets, Inc., Whole Foods Market, Fritz Company, Inc., and Pine River Pre-Pack, Inc. have initiated recalls.

The F.D.A. has established a web site to help consumers and the food industry track the products that have been recalled. Visit for more information.
