Setton Farms in Terra Bella, California, the second-largest pistachio processor in the United States, is recalling roasted pistachio products under suspicion of presence of salmonella. However no illness has been reported due to consumption of its products.

Dr. David Acheson, FDA's associate commissioner said that salmonella strains were found last week during routine test by Kraft Foods, one of about three dozen companies that purchase pistachios from Setton Farms.

Acheson added that the Setton Farms recall is related to the one announced Friday by Kroger, a grocery store chain with stores in 31 states. Kroger recalled Private Selection shelled pistachios from its retail stores because of possible salmonella contamination.

State officials said that Setton sent its roasted pistachios to the Georgia Nut Co., which recalled its Kraft Back to Nature Nantucket Blend trail mix on Wednesday. Setton Farms has initiated a separate recall of three lots of roasted pistachios tied to the positive results in the trail mix.
