Abstract

Objectives: This case-control study investigated risk factors for campylobacteriosis in a rural population. Exposure to live farm animals was hypothesized to increase the risk for Campylobacter jejuni enteritis.

Methods: Incident cases from rural counties reported to the Michigan Department of Community Health and matched controls completed a self-administered postal questionnaire.

Results: Persons engaged in poultry husbandry had increased odds of campylobacteriosis (odds ratio = 6.884; 95% confidence interval (CI) = 1.438, 32.954). There was evidence for a dose-response relationship between the number of types of poultry contact and campylobacteriosis.

Conclusions: We estimate that 18% (95% CI = 6%, 30%) of Campylobacter cases occurring in rural populations are attributable to poultry husbandry. Cases occurred in individuals who were not poultry farmers by occupation.
