A former peanut company executive has been jailed for 28 years in the US for his role in a national salmonella outbreak linked to nine deaths. Stewart Parnell, 61, the ex-owner of the Peanut Corporation of America, was convicted last year of knowingly shipping tainted products. His brother Michael, who worked as a food broker, was given 20 years. The outbreak made hundreds ill and prompted one of the largest food recalls in US history. The brothers were charged after investigators traced the outbreak to the company's plant in Blakely, Georgia in 2009. A former quality control manager at the plant, Mary Wilkerson, was also sentenced to five years in prison.
Is this a game changer?
