BBC News — FBI agents have raided a peanut processing plant blamed for a U.S.-wide outbreak of salmonella poisoning that has been linked to eight deaths. Agents carried out search warrants at the Georgia-based Peanut Corporation of America's plant in the town of Blakely and at its headquarters in Lynchburg. The raid came three days after the Food and Drug Administration said PCA knowingly sold contaminated nuts. A criminal inquiry was launched last month. The firm denies any wrongdoing. An FDA inspection in January found that the plant in Blakely was "not compliant with Current Good Manufacturing Practices required by the FDA". More than 1,550 peanut butter products have now been recalled. A total of 575 people in 43 states have fallen ill September 2008.
