A Prolonged outbreak of Campylobacter infection at a training facility

Abstract

Campylobacter outbreaks are rarely detected despite Campylobacter being the most common food-borne illness notified to public health authorities. We report a prolonged outbreak of Campylobacter occurring over a three month period at a training facility. Seventy-eight cases were detected, 16 of which were confirmed Campylobacter infections. In seven affected groups of people using the facility, the attack rate ranged between 19% and 67%. An investigation of one sporting group showed that illness was associated with consumption of cucumber served at a self-serve salad bar. Six people attending the facility in other weeks also reported illness after eating only at the salad bar. Transmission of Campylobacter ceased after changes were instituted to food preparation and storage in the facility kitchen. Comm Dis Intell 1997;21:57- 61.
