摘要
抗生素残留一直是威胁食品安全的重大问题,为了解银川地区牛乳中抗生素残留情况,采用间接竞争酶联免疫吸附试验(ELISA),对银川地区部分养殖场和超市共计350份乳样进行了头孢类药物和庆大霉素残留的检测。结果显示,来自养殖场的200份乳样中,有4份样品的头孢类药物检测结果不合格,5份样品的庆大霉素检测结果不合格,分别占检测样品的2%和2.5%。来自超市的150份乳样中,有3份样品的头孢类药物检测结果不合格,2份样品的庆大霉素检测结果不合格,分别占检测样品的2%和1.3%。说明在银川地区部分养殖场和超市的牛乳中均存在头孢类药物和庆大霉素残留超标的问题。
Antibiotic residues have been a major threat to food security.In order to understand the residues of cephalosporins and gentamicin in cow milk in Yinchuan, cephalosporins and gentamicin residues were tested on 350 milk samples collected from farms and supermarkets by indirect competitive enzyme-linked immunosorbent assay (ELISA).The results showed that 4 samples of cephalosporin test results and 5 samples of gentamicin test results were unqualified in 200 milk samples from the farms, which accounting for 2% and 2.5% of the samples respectively.From the market in 150 milk samples,3 samples of cephalosporin test results were unqualified and 2 samples of gentamicin test results were unqualified, which accounting for 2% and 1.3% of the samples respectively. It revealed that the cephalosporin and gentamicin excessive residues in milk existed in the farms and supermarkets of Yinchuan.
