[ Food Machinery and Equipment Network Policies and Regulations ] Recently, in the release of the "National Food Safety Standard Maximum Residue Limits for Veterinary Drugs in Foods", 9 national food safety standards for veterinary drug residue detection methods were attached, which also provided reference standards for veterinary drug residue detection. With strong technical support, it also further regulates and guides the healthy development of the industry, and protects people's “food safety at the tip of their tongues”.

A few days ago, relevant departments jointly issued the "Maximum Residue Limits of Veterinary Drugs in Foods of National Food Safety Standards" and 9 national food safety standards for testing methods of veterinary drug residues, which will be implemented 6 months from the date of publication and will be April 1, 2020 Formally implemented. The related standards for veterinary drugs in food this time stipulated 2,191 residue limits and application requirements for 267 kinds (classes) of veterinary drugs in livestock and poultry products, aquatic products, etc., which also marked the entry into a new stage of the construction of a standard system for veterinary drug residues in China.
In addition, there are 9 national food safety standards for the detection of veterinary drug residues, which include liquid chromatography-tandem mass spectrometry, gas chromatography-mass spectrometry, gas chromatography, and high-performance liquid chromatography. The author understands that among the 9 national food safety standards for the detection of veterinary drug residues, liquid chromatography-tandem mass spectrometry is the most common method, with 6 items, mainly related to aquatic products, animal foods, cattle edible tissues, and milk. Detection.
Specifically includes "GB31660.1-2019 National Food Safety Standard for Determination of Macrolide Residues in Aquatic Products-Liquid Chromatography-Tandem Mass Spectrometry", "GB31660.7-2019 National Food Safety Standard for Pig Tissues and Urine Determination of cyproheptadine and clonidine residues by liquid chromatography-tandem mass spectrometry ", GB31660.8-2019 National Food Safety Standard-Determination of phenanthridine residues in bovine edible tissues and milk-liquid chromatography-tandem mass spectrometry Act and so on.
Among them, 3 items are tested in animal foods, for example, "GB31660.4-2019 National Food Safety Standard for Animal Foods. Determination of megestrol acetate and medroxyprogesterone acetate residues. Liquid chromatography-tandem mass spectrometry "" GB31660.5-2019 National Food Safety Standard for Determination of Amantadine Residues in Animal Foods Liquid Chromatography-Tandem Mass Spectrometry "," GB31660.6-2019 National Food Safety Standard for Animal Foods 5 Determination of receptor agonist residues by liquid chromatography-tandem mass spectrometry.
The detection methods for the other three veterinary drug residues include GB31660.2-2019 National Food Safety Standard for Aquatic Products. Octylphenol, nonylphenol, bisphenol A, diethylstilbestrol, estrone, 17α-ethinyl estradiol, 17β-estradiol, determination of estriol residues by gas chromatography-mass spectrometry, GB31660.3-2019 National Food Safety Standard Determination of Flulorin Residues by Gas Chromatography, GB31660.9- Determination of ethoxyamide benzyl methyl ester residues in edible tissues of poultry in 2019 National Food Safety Standard. High Performance Liquid Chromatography.
The author further understands that only from the method of determination of related residues in aquatic products, including liquid chromatography-tandem mass spectrometry, gas chromatography-mass spectrometry, and gas chromatography. From the perspective of instruments and equipment, the determination of macrolide residues in aquatic products (such as Chinese fish, shrimp, crab, shellfish and other edible tissues) is determined by liquid chromatography-tandem mass spectrometry and Phase chromatography-tandem mass spectrometer, analytical balance, vortex mixer, centrifuge , nitrogen blower, ultrasonic oscillator, rotary evaporator, etc.
The determination of octylphenol, bisphenol A, diethylstilbestrol, estriol and other residues in aquatic products uses gas chromatography-mass spectrometry, which requires a gas chromatography-mass spectrometer, analytical balance, vortex mixer, and centrifuge , Nitrogen blowing instrument, homogenizer , solid-phase extraction device, polypropylene centrifuge tube, etc., mainly used for octylphenol, bisphenol A, etc. in fish, shrimp, crab, shellfish, sea cucumber, cormorant and other edible tissues The residual amount is detected. For the determination of flulorin in aquatic products, gas chromatography was used.
"GB31660.3-2019 National Food Safety Standard for Determination of Flulorin Residues in Aquatic Products by Gas Chromatography" clearly states that this standard is applicable to fluorine in edible tissues of aquatic products such as fish, shrimp, crab, mandarin duck, and shellfish. Detection of pill residue. The instruments and equipment involved in the measurement include gas chromatograph, analytical balance, nitrogen blower, homogenizer, vortex mixer, centrifuge, ultrasonic oscillator, rotary evaporator, solid phase extraction device, etc., to ensure relevant residues The measurement is accurate.
With the issuance and implementation of the National Food Safety Standard Maximum Veterinary Drug Residue Limits and 9 national food safety standards for veterinary drug residue detection methods, it not only provides reference standards and strong technical support for veterinary drug residue detection, but also further regulates and standardizes Guide the healthy development of the industry, protect the safety of people's dining table and make people eat more at ease!
