| Sumario: | This study is part of a 2 year disease surveillance project conducted to establish the prevalence of poultry and zoonotic pathogens, including <i>Campylobacter</i> spp., among small poultry flocks in Ontario, Canada. For each post-mortem submission to the Animal Health Laboratory, a pooled sample of cecal tissue was cultured for <i>Campylobacter</i> spp., and a husbandry and biosecurity questionnaire was completed by the flock owner (<i>n</i> = 153). Using both laboratory and questionnaire data, our objective was to investigate demographic, husbandry, and biosecurity factors associated with the presence of <i>Campylobacter</i> spp. in small flocks. Two multivariable logistic regression models were built. In the farm model, the odds of <i>Campylobacter</i> spp. were higher in turkeys, and when birds were housed in a mixed group with different species and/or types of birds. The odds were lower when antibiotics were used within the last 12 months, and when birds had at least some free-range access. The effect of pest control depended on the number of birds at risk. In the coop model, the odds of <i>Campylobacter</i> spp. were lower when owners wore dedicated clothing when entering the coop. These results can be used to limit the transmission of <i>Campylobacter</i> spp. from small poultry flocks to humans. |
