Campylobacter in Poultry: Ecology and Potential Interventions

Area of Science:

• Food Safety
• Veterinary Microbiology
• Public Health

Background:

• Avian hosts, particularly poultry, are natural reservoirs for thermophilic Campylobacter species like Campylobacter jejuni and Campylobacter coli.
• High prevalence rates of Campylobacter colonization are observed in poultry flocks, reaching up to 100% in some broiler farms.
• While Campylobacter is largely commensal in birds, it is a significant cause of human gastroenteritis, with poultry meat being a primary source of exposure.

Purpose of the Study:

• To review current knowledge on Campylobacter in poultry.
• To emphasize the ecology, antibiotic resistance, and interventions related to Campylobacter in poultry.
• To inform strategies for reducing Campylobacter contamination in poultry to mitigate human foodborne illness.

Main Methods:

• This review synthesizes existing research on Campylobacter in avian hosts.
• It examines ecological factors influencing Campylobacter colonization in poultry.
• The review assesses antibiotic resistance patterns and evaluates pre- and postharvest intervention strategies.

Main Results:

• Poultry flocks frequently harbor high levels of thermophilic Campylobacter species.
• Campylobacter, though a commensal in poultry, poses a significant public health risk globally.
• Advances in understanding Campylobacter in poultry have led to the exploration of various control measures.

Conclusions:

• Campylobacter poses a significant food safety challenge linked to poultry consumption.
• Effective interventions targeting Campylobacter in poultry are crucial for reducing human infections.
• Continued research into Campylobacter ecology and resistance is vital for public health protection.
