Surveillance and Reporting
Did You Know?
98% of reported foodborne disease outbreaks involved only one state. Learn more …
CDC has a long history of summarizing outbreak reports from local and state health departments.
State and local public health authorities investigate all foodborne disease outbreaks. CDC coordinates those that involve multiple states; such outbreaks usually result from contaminated food that is widely distributed to many states. Data reported to CDC for each outbreak include the number of illnesses, hospitalizations, and deaths; the pathogens, toxins, and chemical agents that caused illnesses; the implicated food; the settings of food preparation and consumption; and factors contributing to food contamination.1
Knowing more about the foods, germs, and settings where outbreaks occur increases our understanding of its impact on human health and is the first step towards prevention.
