目的了解烟台市市售生鲜肉中违禁硝基呋喃类兽药及β-受体激动剂残留量的污染程度。方法按照《2013年国家食品污染和有害因素风险工作手册》中兽药及违禁药物检测的标准操作程序要求,对烟台市市售30份散装猪肉、羊肉、牛肉、猪肝脏,进行硝基呋喃及其代谢物(呋喃唑酮、呋喃它酮、呋喃西林、呋喃妥因)以及β-受体激动剂(克伦特罗、沙丁胺醇、莱克多巴胺、特布他林)共8项指标的监测。结果抽检样品的合格率为93.3%(28/30),2份不合格(检出克伦特罗),其余7项均未检出。检测的6份牛肉、4份羊肉均合格,均有检疫标识;猪肉合格率为93.3%(14/15),其中2份无检验检疫标识但均合格;猪肝合格率为80.0%(4/5),1份无检验检疫标识且不合格。结论烟台市市售生鲜肉总体质量状况较好,硝基呋喃及其代谢物均未检出,但克伦特罗有阳性结果检出,需要加大监测和监管力度。
