Drug residue is currently one of the serious hazards of aquatic products, with representative types including chloramphenicol, malachite green, nitrofurans, quinolones, and other drugs,If humans consume aquatic products containing drug residues for a long time, the drugs will continue to accumulate in the body. When the concentration reaches a certain level, it will have toxic effects on the human body，Causing significant harm to human safetyIn recent years, the country has also successively introduced relevant policies and regulations,Effectively curb the illegal use of antibiotics, banned compounds, and excessive residues of veterinary drugs in livestock, poultry, and aquatic products,From the source of origin to the entire process of market circulationStrengthen the supervision of aquatic product quality and safetyEnsure the quality and safety of aquatic products.

Regulations on the Administration of Veterinary Drugs of the People's Republic of ChinaArticle 43 alsoClearly stipulate:Prohibit the sale of edible animal products containing prohibited drugs or veterinary drug residues exceeding the standard.

Quality and safety supervision of aquatic products: aquaculture (farms)—Circulation (wholesale market, farmer's market) - dining table (illustrated with a picture to illustrate a cycle)

Fluorescence quantitative immunoassay technology

Fluorescence quantitative immunoassay technology can be considered as a new and relatively mature POCT (real-time on-site detection technology) detection technology in food safety testing. Light quantitative chromatography technology combines immunological technology, chromatographic chromatography technology, biological probe technology, and micro light detection technology, and is a new detection technology in food safety testing. Fluorescence quantitative chromatography technology has the advantages of high sensitivity, quantifiability, convenient operation, and fast detection.

Technical advantages: high sensitivity, quantitative detection, fast detection speed, easy operation, accurate and stable detection results. (illustrated advantages)
