Hypothesis
What are the farm-level risk factors associated with the colonization of broiler flocks with Campylobacter spp.?
Conclusion
Limiting flock size and using treated water may reduce the risk of Campylobacter colonization in broiler flocks.
Supporting Evidence
- 27.4% of flocks tested positive for Campylobacter.
- Increasing median flock size was associated with higher risk of colonization.
- Using official treated water reduced the risk of Campylobacter colonization.
Takeaway
This study found that bigger flocks and certain water sources can make chickens more likely to get sick from Campylobacter, a germ that can make people sick too.
Methodology
Pooled caecal samples from 1,425 flocks were cultured for Campylobacter, with logistic regression models used to analyze risk factors.
Potential Biases
Potential confounding due to correlated variables in the models.
Limitations
Some farms were excluded due to missing data, and the study may not account for all potential confounding variables.
Participant Demographics
Commercial broiler flocks raised in Iceland.
