Arcobacter and Campylobacter are recognized as foodborne pathogens and frequently detected from chicken meat. The purpose of this study was to determine the contamination level by Arcobacter and Campylobacter of chicken meat obtained from the poultry processing plant in Yamaguchi prefecture. Samples were collected from six lots (four poultry farm) from July to December 2018. The evaluation of antimicrobial susceptibility of the isolates also was provided following the methods for broth microdilution testing. A. butzleri and C. jejuni were isolated from all lots, A. cryaerophillus and C. coli were isolated from each one lot. There was no significant difference between in contamination level among different lots (poultry farm) or pre- and post-chiller process. A. butzleri isolates (n=64) were resistant to ampicillin, erythromycin, tetracycline, chloramphenicol, nalidixic acid, ciprofloxacin and ofloxacin. A cryaerophillus isolates (n=2) susceptible to all tested drugs. C. jejuni isolates (n=67) were resistant to nalidixic acid, ciprofloxacin and ofloxacin. C. coli isolates (n=15) were resistant to streptomycin, tetracycline, nalidixic acid, ciprofloxacin and ofloxacin. It became clear from this study that A. butzleri isolates were resistant to some antibiotics commonly used for the treatment of infectious bacterial diseases in human and livestock animals.
