National Salmonella Surveillance Overview
The National Salmonella Surveillance System is based on data collected by state and territorial public health laboratories since the 1970s. Salmonella isolates are submitted to the state or territorial public health laboratory by clinical diagnostic laboratories. The public health laboratory confirms the isolates as Salmonella and performs serotyping according to the Kauffmann-White scheme. State and territorial public health laboratories send reports electronically to CDC through a variety of mechanisms. Initially, all surveillance data were transmitted through the Public Health Laboratory Information System (PHLIS), but other methods of data transmission have been implemented over time; currently data are collected into the Laboratory-based Enteric Disease Surveillance (LEDS) system, which has replaced PHLIS. The Division of Foodborne, Waterborne, and Environmental Diseases (DFWED) in the National Center for Emerging and Zoonotic Infectious Diseases maintains the national Salmonella surveillance data in LEDS. The annual summaries of these data are the only regularly published national source of serotype information for Salmonella.
Serotype-based surveillance provides a mechanism to rapidly detect unusual patterns in the incidence of foodborne and diarrheal pathogens. Rapid analysis of surveillance data allows public health officials to detect unusual disease clusters. Analysis can be conducted at state, regional, or national levels.
