Numerous reports of Salmonella Enteritidis infections from emergency rooms throughout Henrico County, Virginia, were made in early April 2001. Many patients had eaten the pork sandwich from Linh's Bakery in Richmond, Virginia. Investigators tested the sandwich ingredients and environment for evidence of Salmonella. All opened sandwich ingredients were contaminated with Salmonella. Salmonella was found throughout the kitchen, including the sandwich preparation areas. Three of four restaurant workers were infected with Salmonella. The conclusion was that eggs used to make the uncooked sandwich spread were the original source of the bacteria. The food preparation technique provided opportunity for cross-contamination. Improper temperature holding allowed the bacteria to multiply. Cooked foods were not associated with illness.
