摘要
目的为了解广州地区奶类抗生素残留和金黄色葡萄球菌污染状况。方法 2006-2009年期间,采用随机抽样方法分别对我市十个区以及两个地级市共计302份奶类样品进行了抗生素残留、金黄色葡萄球菌以及葡萄球菌肠毒素的检测。金黄色葡萄球菌的检测按照国标GB4789.10进行;抗生素残留和葡萄球菌肠毒素的检测则依照试剂盒的要求进行。结果 302份样品,其中有62份检测到有抗生素残留,阳性率为20.53%;奶粉类为高,29.51%;纯奶类次之,为22.67%。通过对各年份的相互比较,抗生素残留的检出呈逐年上升的趋势。随机抽取的42份奶制品均未检出金黄色葡萄球菌,肠毒素检测阴性;10份生奶有7份检出金黄色葡萄球菌,其中5份肠毒素检测呈阳性。结论广州地区的奶制品存在较高的抗生素残留的不安全因素,生奶类检出抗生素残留、金黄色葡萄球菌及其肠毒素等的情况说明奶源存在污染。因此,监督部门必需更进一步规范生牛奶供应市场,加强对奶制品的抗生素残留的监控,以维护广大人民的身体健康。
