MMWR: Lessons from a Salmonella Outbreak at a County Fair

A 2024 outbreak of Salmonella enterica serotype Agbeni sickened 13 attendees at the Brown County Fair in Mount Sterling, Illinois, highlighting overlooked public health risks at community events. Investigators identified a beer cooler—reused over multiple days without cleaning—as the shared exposure among cases, including attendees who did not eat fair food.

 

Laboratory confirmation, epidemiologic interviews, and AI-assisted hypothesis generation helped pinpoint the nonfood source. The outbreak underscores the importance of standardized hygiene protocols for beverage storage, cooler sanitation, and hand hygiene at public gatherings. Public health communicators can leverage such investigations to reinforce preventive guidance and community awareness for food and beverage safety. Read the CDC's MMWR study here.
