目的:监测了解辽宁省食源性致病菌污染状况、耐药状况和沙门菌血清学分布,指导抗生素的合理应用,控制耐药菌株的传播。方法:按照标准操作程序,对样品进行沙门菌等食源性致病菌的分离鉴定,并对分离株进行血清学鉴定和耐药测定。结果:10大类食品共3625件样品中检出5种致病菌208株,三种食源性致病菌均出现耐药株,耐药率在0%～69.8%。结论:检测结果表明辽宁主要食品均受到食源性致病菌不同程度的污染;部分分离株出现多重耐药,建议政府加强对饲用抗生素的管理,建立食源性耐药菌的风险评估机制。
OBJECTIVE: To monitor and understand the status of food-borne pathogenic bacteria in Liaoning Province, the status of drug-resistance and the serological distribution of Salmonella, guide the rational use of antibiotics and control the spread of drug-resistant strains. Methods: According to the standard operating procedure, the samples were isolated and identified from food-borne pathogenic bacteria such as Salmonella, and the isolates were identified by serology and drug resistance. Results: A total of 208 strains of 5 pathogens were detected in 3625 samples of 10 kinds of foodstuffs. All three kinds of food-borne pathogens showed drug-resistant strains with resistance rates ranging from 0% to 69.8%. Conclusion: The results showed that the main food in Liaoning Province were all contaminated by food-borne pathogens. Some isolates were multidrug-resistant, suggesting that the government should strengthen the management of feed antibiotics and establish the risk assessment mechanism of food-borne resistant bacteria .
