Campylobacter is one of the most common causes of foodborne gastroenteritis. This study aimed to estimate the prevalence and risk factors associated with Campylobacter jejuni and Campylobacter coli species in fresh chicken carcasses for human consumption from farmers’ markets and small food stores in seven localities of Bogotá, Colombia. Ninety-one samples of fresh chicken carcasses were collected from farmers’ markets and small food stores at seven localities in Bogotá. Samples were tested for Campylobacter using the real-time polymerase chain reaction (RT-PCR) and isolation by plating. In order to analyze possible risk factors associated with contamination by Campylobacter spp. in retail chicken carcasses, information was collected through a structured questionnaire and a univariate logistic regression analysis (α=0.05) was used. Forty-two positive samples were obtained for Campylobacter spp., obtaining a prevalence of 46.15%, of which 54.76% corresponded to C. jejuni, 9.52% to C. coli and 35.71% to joint contaminations. C. jejuni was the most prevalent species. Risk factors found included poor cleanliness, infrequency of disinfection, type of establishment, and direct contact of chicken with other food. This study is the first report in the country on the prevalence and risk factors of Campylobacter in retail chicken.
