摘要
以嗜热链球菌为指示菌株,分别采用TTC法和PD法,对随机抽取的我市各大、小超市袋装奶以及市郊散养奶牛新鲜牛奶样品进行抗生素残留检测,结果采用TTC法和PD法检测结果一致,检出60份牛奶样品中的抗生素残留阳性结果一份,阳性检出率为1.67%。但是TTC法与嗜热链球菌纸片法(PD法)相比较,其检测耗时短,检验程序相对简单,更加适合于抗生素残留的快速检测。
Objective To know the situation of antibiotic residual and make a comparative analysis on the detection meth- ods of antibiotic residuall Methods Laboratory detection on the antibiotic residual situation of supermarketps packed milk by TTC and PD methods. Results the result is the same by using TTC method and PD methods. There is positive antibiot- ic residue in the 60 portion samples, and the positive detection rate is 1.67%. Conclusion s Compared TTC method with PD methods, TTC method testing wastes less time, and the testing progrom is more simple. Therefore, TTC method is more suitable to test antibiotic residue quickly. The main factor inducing antibiotic residual is to treat dairy cowps disea- ses. It is suggested that raising households should strengthen feeding and management to reduce the diseases of dairy cow and abide by the withdrawal time strictly to ensure the health of consumers.
