WASHINGTON ( CNN ) -- A California food processing plant is voluntarily recalling up to 1 million pounds of roasted pistachio products that may have been contaminated with salmonella , the Food and Drug Administration announced Monday . Salmonella strains were found last week during routine test by Kraft Foods , one company that purchased the nuts . The nuts came from Setton Farms in Terra Bella , California , about 75 miles south of Fresno . They were largely distributed in 2,000-pound containers to food wholesalers who would then package them for resale or incorporate them as ingredients in other products , such as ice cream and trail mix . No illnesses have been linked to this case , said Dr. David Acheson , FDA 's associate commissioner . But salmonella strains were found last week during routine test by Kraft Foods , one of about three dozen companies that purchase pistachios from Setton Farms , he said . Kraft notified the FDA on March 24 . Setton Farms did not immediately respond to CNN requests for comment . Acheson emphasized that unlike the recent case of salmonella-tainted peanut butter , this recall was not prompted by an sickness outbreak , saying the decision was a `` proactive '' move . He said the FDA has received two recent complaints , from the East and West coasts , from people who say they became ill after eating pistachio products , but a link to Setton Farms has not been confirmed , he said . The FDA is advising consumers not to eat any pistachio products , but not to throw them out , either , because additional recalls are likely and having products that could be turned in would allow for easier tracing of contamination . The agency is setting up a Web site to update the public . Dr. Jeff Farrar , head of the California health department 's food and drug division , said it 's likely that the roasted pistachios will be found in a wide variety of products . He noted that Setton Farms is the second-largest pistachio processor in the nation . Raw pistachios are roasted to a temperature that should kill salmonella , Acheson said . Because the roasted products tested positive for salmonella suggest cross-contamination with raw products . 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 . Kroger , in a statement Friday , said no illnesses have been reported in connection with the product . In February , Kroger was among retailers that recalled peanut products tied to the Peanut Corporation of America , a Virginia-based company accused by the FDA of knowingly selling peanut butter and peanut paste that was contaminated with salmonella . PCA 's peanut processing plant in Blakely , Georgia , is being investigated in connection with a salmonella outbreak that has sickened more than 500 people and has been linked to eight deaths .
The pistachios , mostly sold to wholesalers , came from Setton Farms in California . Kraft is one of three dozen companies to purchase pistachios from Setton Farms . No illnesses have been linked to this case so far . Comment:
