On July 23, 2004, the Food and Drug Administration and Pennsylvania Department of Health announced that a case control study had been conducted, and the conclusions based off the study were that Salmonella-contaminated Roma tomatoes were the source of an outbreak linked to sandwiches, salads, and wraps sold at Sheetz retail food stores between July 2 and July 8. In the end, over 480 people had confirmed Salmonella poisoning after eating at Sheetz.
The reported outbreak was linked by a DOH investigation to Roma tomatoes sold in Sheetz’ sandwiches, wraps, and salads. the tomatoes were supplied to Sheetz by Coronet Foods of West Virgina. The Roma tomatoes were determined to be the primary source of the Salmonella Javiana bacteria.
Salmonella litigation commenced against Coronet Foods of West Virginia on Monday, July 19, 2004, when Marler Clark filed a Salmonella lawsuit against the company on behalf of a Butler County, PA couple.
