title: Dynamic ofCampylobacterSpecies Contamination Along a Poultry Slaughtering Chain.
abstract: The prevalence of Campylobacters was studied in a poultry farm and along the slaughtering chain. Fifteen swabs from a farm and 75 samples (swabs and rinsates) from its slaughterhouse were collected. All the faecal and cloacal farm swabs were contaminated byCampylobacter jejuniandC. coliagainst 50% for breast swabs.C. jejunihad a concentration of 6.26, 6.34 and 5.38 Log10CFU/mL in faecal, cloacal and breast swabs respectively. Rinsates showed an almost constant concentration of Campylobacters (6 Log10CFU/mL) with a predominance of the presumptiveC. jejuni.C. lariwas found in 22% of eviscerated samples. Faecal coliforms andE. coli, used as indicators, were detected in all samples (5.46 and 5.15 Log10CFU/mL, respectively). Final chilling and chlorine (50 ppm) treatments decreased them to acceptable levels, unlike for Campylobacters. Further investigation of the dynamics of Campylobacters and their response to prevention and treatment measures is required.
