ALBANY, Ga. (AP) _ The former manager of a peanut processor linked to a deadly outbreak of salmonella says he was “scared to death” the first time he saw that a lab test had identified the deadly pathogen in a product. Samuel Lightsey continued testifying Tuesday against his former boss at Peanut Corp. of America, Stewart Parnell, and two others. Lightsey worked for 17 years in food quality assurance before joining Parnell’s company. Lightsey said he saw his first positive test for salmonella in 2008, not long after starting at PCA. Parnell and his brother, food broker Michael Parnell, are accused of shipping tainted products to customers and covering up lab tests showing they contained salmonella. Stewart Parnell and the Georgia plant’s quality assurance manager, Mary Wilkerson, also are charged with obstructing justice.
