WASHINGTON, D.C.: Three people convicted over a nationwide salmonella outbreak were sentenced Monday to tough sentences of up to 28 years in prison, the US Justice Department said. Two ex-officials of and a broker for the Peanut Corporation of America (PCA) were jailed in Albany, in the US state of Georgia, for their roles in a conspiracy to defraud consumers about peanut health risks. Expert evidence at their trial showed tainted food led to a salmonella outbreak in 2009. More than 700 reported cases of salmonella poisoning, including nine deaths, in 46 states resulted. Stewart Parnell, 61, the ex-owner and president of PCA, was sentenced to 336 months, or 28 years, in prison plus three years of supervised release. Michael Parnell, 56, Stewart Parnell’s brother and a food broker who worked on behalf of PCA, was sentenced to 20 years plus three years of supervised release. Mary Wilkerson, 41, who held various positions at PCA’s Blakely, Georgia plant was sentenced to five years.
