CSTE Position Statement(s)
Definition: An incident in which two or more persons experience a similar illness after ingestion of a common food, and epidemiologic analysis implicates the food as the source of the illness.
Symptoms of illness depend upon etiologic agent. Please see the "Guidelines for Confirmation of Foodborne-Disease Outbreaks".1
Laboratory Criteria For Diagnosis
Diagnostic laboratory criteria depend upon the etiologic agent. Please see the "Guidelines for Confirmation of Foodborne-Disease Outbreaks".1
There are two exceptions: one case of botulism or chemical poisoning linked to a food item constitutes a notifiable outbreak.
Data sharing: Notification to CDC of confirmed cases of foodborne disease outbreaks (preferably using the CDC National Outbreak Reporting System) is recommended.2
