Abstract

Antimicrobial-resistant bacterial contamination of meat poses a significant global public health risk. We aimed to determine antimicrobial resistance profiles and trends of Escherichia coli recovered from carcasses of healthy food-producing animals in South Korea during 2010-2023. In total, 4748 E. coli isolates obtained from cattle (n = 1582), pigs (n = 1572), and chickens (n = 1594) were assessed for susceptibility to 12 antimicrobials. Antimicrobial resistance was different among samples. Overall, antimicrobial resistance was high in pigs and chicken carcasses. More than about 80% of isolates from pigs and chickens exhibited resistance to one or more antimicrobials. Among the tested antimicrobials, resistance to ampicillin, chloramphenicol, streptomycin, and tetracycline was significantly higher in pigs and chickens compared with cattle (p < 0.05). Moreover, chicken isolates showed much higher resistance to nalidixic acid and ciprofloxacin than other samples. Resistance to critically important antimicrobials, colistin, remained less than about 1%, while resistance to ceftiofur showed increased trends in pig and chicken samples. Higher multidrug-resistant (MDR) isolates were identified in chickens and pigs compared with cattle (p < 0.05). Furthermore, most MDR patterns include streptomycin and tetracycline resistance. MDR E. coli contaminating meat during slaughter can be transmitted to humans via the food chain. Thus, prudent use of antimicrobials and proper hygienic practices are urgently needed to reduce the risk of transmission.

2010-2023年韩国食用动物尸体分离大肠杆菌耐药性分析

肉类的抗微生物细菌污染对全球公共卫生构成重大威胁。我们的目的是确定2010-2023年韩国健康食品生产动物尸体中回收的大肠杆菌的抗菌素耐药性概况和趋势。总共从牛（n = 1582）、猪（n = 1572）和鸡（n = 1594）中分离出4748株大肠杆菌，对12种抗菌素进行了敏感性评估。不同样品的耐药程度不同。总体而言，猪和鸡尸体的抗菌素耐药性很高。约80%以上的猪和鸡分离株表现出对一种或多种抗菌素的耐药性。在所测抗菌素中，猪和鸡对氨苄西林、氯霉素、链霉素和四环素的耐药性显著高于牛（p < 0.05）。此外，鸡分离株对萘啶酸和环丙沙星的耐药性明显高于其他样品。对至关重要的抗菌素粘菌素的耐药性仍不到1%，而对头孢噻呋的耐药性在猪和鸡样本中显示出增加的趋势。与牛相比，鸡和猪的耐多药菌株较高（p < 0.05）。此外，大多数耐多药模式包括链霉素和四环素耐药。在屠宰过程中污染肉类的耐多药大肠杆菌可通过食物链传播给人类。因此，迫切需要谨慎使用抗微生物药物和适当的卫生习惯，以减少传播风险。

期刊介绍： Foodborne Pathogens and Disease is one of the most inclusive scientific publications on the many disciplines that contribute to food safety. Spanning an array of issues from "farm-to-fork," the Journal bridges the gap between science and policy to reduce the burden of foodborne illness worldwide. Foodborne Pathogens and Disease coverage includes: Agroterrorism Safety of organically grown and genetically modified foods Emerging pathogens Emergence of drug resistance Methods and technology for rapid and accurate detection Strategies to destroy or control foodborne pathogens Novel strategies for the prevention and control of plant and animal diseases that impact food safety Biosecurity issues and the implications of new regulatory guidelines Impact of changing lifestyles and consumer demands on food safety.
