In December 2009, the FDA ordered the recall of peanut butter traced to ConAgra's Sylvester, Georgia processing plant after some 370 reported health problems after eating it. The plant produced Peter Pan and Great Value Peanut Butter, as well as bulk peanut butter sold to restaurants.
Peanut Corp. of America, a bulk peanut butter maker, recalled 21 lots implicated in the outbreak. Grocery store brands weren't among those causing the problem, according to the US Centers for Disease Control and Prevention (CDC).
The CDC investigation led to institutions such as schools, hospitals, and nursing homes that used King Nut brand peanut butter.
