      目的 分析2020年西安市淡水鱼中的兽药残留情况。方法 在西安市不同区域随机抽取淡水鱼242批次, 采用液相色谱-串联质谱法检测淡水鱼中孔雀石绿、隐色孔雀石绿、氯霉素、硝基呋喃类、地西泮及喹诺酮类等10种兽药残留, 并对实验数据进行分析。结果 242批次淡水鱼中共有24批次不合格, 不合格率为9.9%, 不合格项目涵盖恩诺沙星(以恩诺沙星与环丙沙星之和计)、氧氟沙星、地西泮、呋喃唑酮代谢物等, 不合格淡水鱼品种涉及泥鳅、鲫鱼、鲤鱼、黑鱼、鲈鱼、草鱼。结论 西安市淡水鱼存在部分兽药残留, 需要加强对喹诺酮类和硝基呋喃类药物, 尤其是地西泮等禁用药物在生产、销售和使用过程的管理。

英文摘要:

      Objective To analyze the veterinary drug residues in freshwater fish in Xi’an in 2020. Methods A total of 242 batches of freshwater fish were randomly selected from different regions in Xi’an. The residues of 10 veterinary drugs such as malachite green, leucomalachite green, chloramphenicol, nitrofurans, diazepam and quinolones in freshwater fish were detected by liquid chromatography-tandem mass spectrometry and the experimental data were analyzed. Results A total of 24 batches of 242 freshwater fish were found to be unqualified, with the unqualified rate of 9.9%. The unqualified items included enrofloxacin (calculated based on the sum of enrofloxacin and ciprofloxacin), ofloxacin, diazepam, and furazolidone metabolites. The unqualified freshwater fish varieties included loach, crucian carp, carp, snakehead, bass and grass carp. Conclusion There are some veterinary drug residues in freshwater fish in Xi’an, so it is necessary to strengthen the management of quinolones and nitrofurans, especially diazepam and other banned drugs in the process of production, sale and use.
