央视新闻客户端消息:记者今天从国家标准委了解到,国际标准化组织近日发布两项由我国牵头制定的兽药残留检测方法国际标准,分别为《鸡组织及鸡蛋 尼卡巴嗪标志物残留量的测定 液相色谱—串联质谱法》《肉、鱼及其制品 氟喹诺酮类药物残留量的测定 高效液相色谱—串联质谱法》。
尼卡巴嗪,俗称“球虫净”,为常用抗鸡球虫病兽药,摄入人体存在健康风险。此次发布的标准采用固相萃取净化与同位素内标结合液相色谱-质谱法,可有效消除磷脂、油脂和蛋白质等基质干扰,实现精准检测。相比其他标准,该方法更高效、灵敏、准确,单个样品检测周期缩短约50%,化学试剂消耗下降约25%,可满足不同国家和组织对残留限值的要求。
氟喹诺酮为广谱抗生素,广泛用于畜禽及水产养殖,长期摄入可危害健康并引发耐药性。此次发布的标准适用于检测肉类、肝肾、鱼肉及加工食品中常见的五种氟喹诺酮药物残留,包括恩诺沙星、环丙沙星、诺氟沙星、氧氟沙星和培氟沙星,通过超声萃取结合溶剂净化前处理,配合高效液相色谱-串联质谱法,显著提高检测效率与灵敏度。与既有方法相比,新方法前处理时间缩短约50%,实验耗材成本降低约65%,恩诺沙星、氧氟沙星灵敏度提升约2.3倍,可满足国际残留限量管控要求。
两项国际标准的发布,将统一不同国家和地区的检测方法,降低因技术差异引发的贸易纠纷和合规成本,提升食品安全水平,助力食品领域国际贸易便利化。
