Gastrointestinal illness among contract construction workers at a chicken processing facility—Minnesota, 2016

Background: After Campylobacter infection was reported in a contract construction worker (contractor) at a chicken processing facility, we described the illness and determined illness associations with workforce exposure. Methods: Case finding was conducted by reportable disease surveillance and contractor interviews. A case was defined as either diarrhea and fever, or diarrhea lasting ≥3 days during January-September, 2016. Results: Fourteen cases were identified among 74 contractors interviewed; four were laboratory-confirmed (two Campylobacter, two Salmonella). Cases were more likely to perform electrical work (odds ratio [OR] 10.4, P < 0.001), take breaks in unofficial areas (OR 6.4, P = 0.01), bring drinks into work areas (OR 4.2, P = 0.02), and have contact with poultry fluids (OR 6.4, P = 0.03). Only 23 (31%) contractors reported infectious disease prevention training. Conclusions: This outbreak emphasizes the importance of training contractors for all potential hazards. Host employers and staffing agencies share responsibility for contractor safety.
