Enteropathogenic Escherichia coli is a foodborne pathogen that produces potentially fatal infant diarrhea, noticeably in developing countries. The aim of this study was to detect EPEC contamination by PCR at different stages of the chicken slaughtering process. We collected swabs from chicken cloacae and washed carcasses (external and visceral cavity) during the slaughtering process in 3 sampling occasions. Unwashed eviscerated carcasses were also sampled (at the visceral cavity) in the second and third sampling occasions. Enteropathogenic Escherichia coli was detected in 6 to 28% of cloacal samples, 39 and 56% of unwashed eviscerated carcasses, and 4 to 58% of washed carcasses. None of the samples were positive for bfpA, suggesting contamination with atypical EPEC. The detection of EPEC at different stages of the chicken slaughtering process showed that the proportion of contaminated samples remained or even increased during processing. In addition, the high proportion of contaminated carcasses during chicken processing represents a risk for the consumers and a challenge to improve procedures for those working in the sanitary control service.
