A total of 770 samples of retail raw meat were examined for the presence of Campylobacter spp. The samples were obtained randomly from 232 retail stores in Korea from September 2001 to April 2006. The highest contamination rates were observed in chicken meat (220 181.4%] of 270 samples), whereas the rates of contamination in pork and beef were extremely low (1.6 and 1.2%, respectively). The antibiotic-resistant patterns of the 317 Campylobacter isolates were examined by the agar dilution method. Resistance to doxycycline was the most common (97.5%), followed by ciprofloxacin (95.9%), nalidixic acid (94.6%), tetracycline (94.6%), enrofloxacin (84.2%), and erythromycin (13.6%). All Campylobacter isolates from the retail raw meat were resistant to at least one of the six antibiotics tested, and 296 isolates (93.4%) showed multidrug (four or more antibiotics) resistance. This demonstrates that the multidrug-resistant Campylobacter species are widespread in meats in Korea. Therefore, further investigations will be needed to determine appropriate methods for eliminating Campylobacter contamination in industrial chicken production and food chains.
共检测了770份零售生肉样本中的弯曲杆菌属。这些样本于2001年9月至2006年4月从韩国232家零售店随机获取。鸡肉的污染率最高（270份样本中有181.4%，即220份），而猪肉和牛肉的污染率极低（分别为1.6%和1.2%）。采用琼脂稀释法检测了317株弯曲杆菌分离株的抗生素耐药模式。对强力霉素的耐药最为常见（97.5%），其次是环丙沙星（95.9%）、萘啶酸（94.6%）、四环素（94.6%）、恩诺沙星（84.2%）和红霉素（13.6%）。零售生肉中的所有弯曲杆菌分离株对所检测的六种抗生素中的至少一种耐药，296株分离株（93.4%）表现出多重耐药（对四种或更多抗生素耐药）。这表明多重耐药弯曲杆菌在韩国肉类中广泛存在。因此，需要进一步研究以确定消除工业鸡肉生产和食物链中弯曲杆菌污染的合适方法。
