According to the Associated Press, federal food safety officials warned Monday that consumers should stop eating all foods containing pistachios while they figure out the source of a possible salmonella contamination.
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 a portion of the roasted nuts it has been shipping since last fall. A Setton spokeswoman said that amounts to more than 2 million pounds of nuts.
Two people called the FDA complaining of gastrointestinal illness that could be associated with the nuts, but the link hasn’t been confirmed, Acheson said. Still, the plant decided to shut down late last week, officials said.
The recalled nuts represent a small fraction of the 55 million pounds of pistachios that the company’s plant processed last year and an even smaller portion of the 278 million pounds produced in the state in the 2008 season, according to the Fresno-based Administrative Committee for Pistachios.
California alone is the second-largest producer of pistachios in the world.
The FDA learned about the problem last Tuesday, when Kraft Foods Inc. notified the agency that it had detected salmonella in roasted pistachios through routine product testing. Kraft and the Georgia Nut Co. recalled their Back to Nature Nantucket Blend trail mix the next day.
The FDA contacted Setton Pistachio and California health officials shortly afterward, in what Acheson called a “proactive move.”
By Friday, grocery operator Kroger Co. recalled one of its lines of bagged pistachios because of possible salmonella contamination, saying the California plant also supplied its nuts. Those nuts were sold in 31 states.
For nuts, roasting is supposed to kill the bacteria. But problems can occur if the roasting is not done correctly or if roasted nuts are re-contaminated. That can happen if mice, rats or birds get into the facility.
Last winter, a national salmonella outbreak was blamed on a Georgia company under federal investigation for flouting safety procedures and knowingly shipping contaminated peanuts.
The outbreak is still ongoing. More than 690 people in 46 states have gotten sick. Nearly 3,900 products made with peanut ingredients from Peanut Corp of America have been recalled.
California public health authorities have taken hundreds of samples at Setton’s processing facility, but lab results have not yet determined whether salmonella was found at the plant, Farrar said. The food companies’ own tests of the contaminated products isolated four different types of salmonella, but none were the same strain as the one found in the peanuts, Acheson said.
