目的了解生牛乳中金黄色葡萄球菌污染状况及其耐药性,预防食源性疾病的发生。方法 2012年收集重庆市各地奶站、养殖场及奶牛养殖户150份,生牛乳按GB4789.10-2010方法进行检测,并对检出的金黄色葡萄球菌作药物敏感试验。结果 150份生牛乳样品共检出金黄色葡萄球菌37株,检出率为24.67%(37/150)。金黄色葡萄球菌对9种抗生素出现不同程度的耐药,以青霉素为最高,达89.19%,四重以上耐药菌株有13株,达35.14%。结论生牛乳中金黄色葡萄球菌污染程度高,耐药及多重耐药严重。必须加强生牛乳卫生管理及生产过程的消毒管理,控制抗生素的使用,建立相应的食源性疾病的监测系统,严防食源性疾病的发生。
Objective To understand the status and drug resistance of Staphylococcus aureus in raw milk and to prevent the occurrence of foodborne diseases. Methods In 2012, 150 milk stations, farms and dairy farmers in Chongqing were collected. Raw milk was tested according to the method of GB4789.10-2010, and drug-susceptible tests of the detected Staphylococcus aureus were conducted. Results 37 strains of Staphylococcus aureus were detected in 150 samples of raw milk, the detection rate was 24.67% (37/150). Staphylococcus aureus to 9 kinds of antibiotics to varying degrees of resistance to penicillin as the highest, up to 89.19%, over four resistant strains 13, up 35.14%. Conclusion Staphylococcus aureus in raw milk has a high degree of pollution and is resistant to multiple drug-resistance. The hygiene management of milk and the disinfection management of the production process must be strengthened to control the use of antibiotics and establish the corresponding foodborne disease monitoring system to prevent the occurrence of foodborne diseases.
