Web-based Investigation of Multistate Salmonellosis Outbreak

Abstract

We investigated a large outbreak of Salmonella enterica serotype Javiana among attendees of the 2002 U.S. Transplant Games, including 1,500 organ transplant recipients. Web-based survey methods identified pre-diced tomatoes as the source of this outbreak, which highlights the utility of such investigative tools to cope with the changing epidemiology of foodborne diseases.
