In 1963, the U.S. Centers for Disease Control and Prevention (CDC), FDA, and USDA and all state health departments joined together to establish the Salmonella Surveillance Program. National Salmonella surveillance data are collected through passive surveillance of laboratory-confirmed human Salmonella isolates. Clinical diagnostic laboratories submit Salmonella isolates to state and territorial public health laboratories, where they are confirmed and serotyped according to the Kauffmann-White scheme.
