National Outbreak Reporting System

Overview
The National Outbreak Reporting System' is a Web-based application for states to report foodborne, waterborne, and other outbreaks electronically. Information collected includes the number ill, dates and places of outbreak, percent of cases by age group and gender, symptoms, incubation period and duration of illness, implicated food or water item, contributing factors leading to food or water contamination, source of implicated food or water, and food recall or other public health response.

Data are used for annual summary reports of foodborne illness as well as for the monitoring of multistate outbreaks. The National Outbreak Reporting System was developed by CDC as a successor system to the Electronic Foodborne Outbreak Reporting System.
