农贸市场水产品中兽药残留快速筛查分析

目的 依托2019年广州市食用农产品快检专项，调查分析本市农贸市场在售水产品的质量安全状况，为水产品的质量安全监管提供新思路。方法 以广州市农贸市场销售的水产品作为调查对象，结合近几年监督抽检结果，针对高风险品种进行抽检，采用胶体金免疫层析法对水产品中孔雀石绿、氯霉素、喹乙醇代谢物、呋喃西林代谢物、呋喃唑酮代谢物等项目进行快速检测，并对其结果进行统计分析，形成重点品种和重点项目清单。结果 抽检了2702批次水产品，检出不合格样品250批次，不合格检出率为9.25%；兽药残留问题比较突出的品种有鳜鱼、黄骨鱼、乌鳢、鲮鱼、鲍鱼蚌、石螺、鹰爪虾、罗氏虾、鳌虾；贝类主要不合格项目为氯霉素，鱼类主要不合格项目为孔雀石绿和氯霉素、硝基呋喃，虾类主要不合格项目为氯霉素及硝基呋喃。结论 通过对水产品中兽药残留快速检测分析，筛查出重点检测品种、项目，为提升水产品质量安全监管的靶向性和针对性提供技术支撑。

Rapid screening analysis of veterinary drug residue in aquatic products in agricultural trading market

Objective Based on the fast inspection of edible agricultural products in Guangzhou in 2019, the quality and safety status of aquatic products sold in the agricultural trading market in Guangzhou was investigated. Methods Taking the aquatic products sold in the agricultural trading market in Guangzhou as the survey object, combined with the results of supervision and sampling in recent years, the high-risk products were sampled and colloidal gold immunochromatography was carried to screening the residues of veterinary drugs, include malachite green, chloramphenicol, Olaquindox metabolite, nitrofurazone metabolite, and furazolidone metabolite in aquatic products. the results were statistically analyzed, and the key varieties and projects were proposed. Results A total of 2702 aquatic products were sampled, and 250 batches of unqualified samples were identified, with a unqualified rate of 9.25%. Products with Seriously exceeded veterinary drug residue include mandarin fish, yellow bone fish, black snakehead, abalone mussel, stone snail, mud carp, eagle claw shrimp, prawn lobster, crayfish. The main risk factors for shellfish was chloramphenicol, for the fishes were malachite green and chloramphenicol, nitrofuran, and for the shrimps were chloramphenicol and nitrofuran. Conclusion Through rapid detection and analysis of veterinary drug residues in aquatic products, the key varieties of aquatic products and veterinary drugs were screened to provide technical support for improving the targeting and pertinence of aquatic product quality safety supervision.
