(AP) - Federal food officials are warning people not to eat any food containing pistachios because of possible contamination by salmonella, in another food scare sure to rattle consumers already upset by the contamination of peanuts with the same bacteria.

The Food and Drug Administration said central California-based Setton Pistachio of Terra Bella Inc., the nation's second-largest pistachio processor, was voluntarily recalling more than 2 million pounds of its roasted nuts shipped since last fall.

Lee Cohen, the production manager for Setton International Foods Inc., said the company does not believe pistachios were contaminated by a human or animal source in its plant. He said the company suspects that roasted pistachios sold to Kraft Foods Inc. may have become mixed at Setton's plant with raw nuts that could have contained traces of the bacteria.
