摘要/Abstract

摘要： 为评估屠宰和预冷阶段猪肉中兽药残留分布情况，根据NY/T 1897—2010《动物及动物产品兽药残留监控抽样规范》屠宰动物计算抽样的方法，对生猪屠宰阶段和预冷阶段中肌肉和内脏样品进行随机抽样240 份，采用超高效液相色谱-飞行时间质谱结合增强型脂质去除技术检测不同猪肉样品中43 种兽药残留，并采用食品安全指数（food safety index，IFS）对兽药残留进行风险评估。结果表明，磺胺二甲嘧啶、二氟沙星和恩诺沙星在猪肉样品中检出，检出率为5%，含量为2.43～19.94 μg/kg。检出样品经预冷后检测结果与屠宰时差异不明显，说明在屠宰和预冷阶段中没有43 种兽药的二次污染。同时对江苏南京市售猪肉进行抽样检测，样品检出率为4.4%，IFS与值均远小于1表明南京市猪肉产品中43 种兽药残留对人群健康不会造成危害。

Abstract: The distribution of veterinary drug residues in pork meat during slaughter and pre-cooling was evaluated in this experiment. A total of 240 samples of pork and viscera were randomly collected according to sampling method specified in the Sampling operating specification for the livestock and poultry and their products in slaughtering enterprises (NY/T 1897-2010), and they were analyzed for 43 veterinary drug residues by enhanced matrix removal lipid (EMR-L) cleanup followed by ultra-high performance liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry (UHPLC-Q-TOF/MS). Meanwhile, risk assessment of veterinary drug residues was carried out based on food safety index (IFS). The results showed that sulfamethazine, difloxacin and enrofloxacin were detected in the 240 samples. The detection rate of the 43 veterinary drugs was 5% at levels ranging from 2.43 to 19.94 μg/kg. The difference between the detection results after rigor mortis and maturation was not significant, indicating that there was no secondary pollution of the 43 veterinary drugs during slaughter and processing. At the same time, pork samples sold in Nanjing were collected and veterinary drug residues were detected in these samples with a detection rate of 4.4%. The IFS and values were found to be much less than 1, indicating that the levels of 43 veterinary drugs residues in pork products in Nanjing were acceptable.
