Subway Salads and Sandwiches Restaurant Food Worker 1999

Patrons of two Subway Restaurant outlets that were located in northern neighborhoods of Seattle, Washington, developed hepatitis A. Some of the food workers were tested for hepatitis A; among these food handlers no evidence of hepatitis A was found. There were rumors about an ill food handler who had worked at both restaurant outlets during the likely period of exposure. This food handler was never found for testing. Neither Subway Restaurant outlet had a written handwashing policy. Poor supervision of staff and movement of staff between the two outlets probably contributed to the outbreak.
