Outbreak Surveillance Data

ª Reporting System (EFORS) without confirmation of etiology by CDC staff; all etiologies are as reported by the state. Etiologies of outbreaks prior to 2001 had been confirmed by CDC staff. Therefore some differences may exist comparing 2001 - 2007 data with that from prior years.

Note: The above annual listings include information received by CDC after publication of "Surveillance for Foodborne-Disease Outbreaks, United States, 1993-1997," (CDC Surveillance Summaries, March 17, 2000; 49/Ss-1). The data provided in the listing may therefore differ from the published summary data.
