Records of Foodborne Disease outbreaks In the U.S.A
Reporting of foodborne disease in the United States began in the 1920s When the Public Health Service first prepared annual summaries of milkborne disease.
In 1938, reporting of foodborne disease was broadened to include diseases transmitted through all food and water.
Data from these early surveys led to widespread adoption of public health measures such as pasteurization of milk and chlorination of water.

An outbreak is defined as two or more persons having a similar illness after ingestion of food at a specific time and place. Only botulism is an exception, where a single case is all that is necessary to constitute an outbreak.
In the period between 1983 and 1987,2,397 outbreaks involving 91,678 cases of foodborne disease were reported to the CDC .
Less than half the reported outbreaks had an identified cause, indicating the need for improved methodologies to identify pathogens.
Of those instances in which the cause was determined, 66% of the outbreaks and 92% of the case were of bacterial origin, 26% of the outbreaks and 2% of the cases were from chemical agents, 4% of the outbreaks and under 1% of the cases were due to parasites, and 5% of both outbreaks of foodborne and case were viral in origin.
