Dynamic of Campylobacter Species Contamination Along a Poultry Slaughtering Chain
نویسندگان
چکیده
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 by Campylobacter jejuni and C. coli against 50% for breast swabs. C. jejuni had a concentration of 6.26, 6.34 and 5.38 Log10 CFU/mL in faecal, cloacal and breast swabs respectively. Rinsates showed an almost constant concentration of Campylobacters (6 Log10 CFU/mL) with a predominance of the presumptive C. jejuni. C. lari was found in 22% of eviscerated samples. Faecal coliforms and E. coli, used as indicators, were detected in all samples (5.46 and 5.15 Log10 CFU/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.

The incidence of human infections caused by Campylobacter jejuni and Campylobacter coli, the main bacterial agents of gastrointestinal disease, has been increasing worldwide. Here, we review the role of poultry as a source and reservoir for Campylobacter. Contamination and subsequent colonization of broiler flocks at the farm level often lead to transmission of Campylobacter along the poultry p...

BACKGROUND Campylobacter is the most common cause of bacterial enteritis worldwide. Handling and eating of contaminated poultry meat has considered as one of the risk factors for human campylobacteriosis. Campylobacter contamination can occur at all stages of a poultry production cycle. The objective of this study was to determine the occurrence of Campylobacter during a complete turkey product...
