This study aimed to investigate the prevalence and antimicrobial sensitivity of Campylobacter jejuni and Campylobacter coli in retail meat (chicken, beef, pork, venison, wild boar, horse, lamb and mutton) in Tokyo (Japan) from 2010 to 2019. Furthermore, the resistance mechanism of erythromycin (EM)-resistant strains was analysed. C. jejuni had a highly positive rate in domestic chicken meat (53.4%, 334/626 samples), domestic chicken offal (49.3%, 34/69 samples), and domestic beef offal (28.3%, 47/166 samples), while C. coli had a high positivity rate in domestic pork offal (31.7%, 44/139 samples). The positive rate of C. jejuni was significantly higher in offal than that in meat in domestic beef, while the positive rate of C. coli was significantly higher in offal than that in meat in domestic beef and domestic pork (p<0.05). In the isolates, 1.0% (6/631 strains) of C. jejuni and 36.2% (55/152 strains) of C. coli were EM resistant, with 41.5% (262/631 strains) of C. jejuni and 65.1% (99/152 strains) of C. coli being ciprofloxacin resistant. A2075G mutation of the 23S rRNA gene was confirmed in all EM-resistant strains.
