Updated from 12:04 p.m. EDTAs the pistachio became the latest victim of salmonella, retailers were voluntarily recalling the nuts. The Food and Drug Administration said Monday that Setton Pistachio of Terra Bella was voluntarily recalling more than 2 million pounds of roasted nuts shipped since last fall because of possible Salmonella contamination. "The number of products that are going to be recalled over the coming days will grow, simply because these pistachio nuts have then been repackaged into consumer-level containers," said Dr. David Acheson, assistant commissioner for food safety, according to The Associated Press. Though the presence of Salmonella hasn't been confirmed, the FDA advises people to avoid eating products that contain pistachios. Kroger ( KR) has voluntarily recalled its Private Selection pistachios, not long after it recalled peanut butter ice cream products because of salmonella worries. Krogers shares were recently down 0.5% to $21.34. Last Tuesday, Kraft ( KR) notified the FDA that routine tests found Salmonella in roasted pistachios, prompting it and Georgia Nut Co. to recall their Back to Nature Nantucket Blend trail mix. Kraft shares were up 2.7% to $22.43 in recent trading. Whole Foods ( WFMI), which earlier this month recalled peanuts and peanut-containing products, was recently up 0.4% to $17.04. Elsewhere: Safeway ( SWY) shares were recently up 1% to $20.38. Supervalu ( SVU), which according to Reuters was pulling all pistachios and pistachio-containing products from its shelves until more information is available, saw its shares rise 3.2% to $14.37. Great Atlantic & Pacific Tea ( GAP) was up 3.2% to $5.44. Costco ( COST), whose recall list can be found here, was up 0.6% to $46.51. BJ's Wholesale ( BJ) was up 0.1% to $32.25. Wal-Mart ( WMT), which has recalled a number of products in March, was up 1.3% to $52.43. Winn Dixie ( WINN) was up 1% to $9.71.
