Sulfa drugs (sulfa drugs) are a class of synthetic antibacterial drugs. Due to the wide antibacterial spectrum, convenient use and low price of sulfonamide drugs, in order to increase the breeding output, it is widely used in feed addition and animal growth. Overdose of sulfonamides themselves can cause gastrointestinal irritation, kidney damage, allergies, drug resistance and other side effects, and sulfonamides residues can cause allergic reactions to those who are allergic to these drugs, and the accumulation of such drugs in the body for a long time It can cause allergic reactions and even cancer. The Codex Alimentarius Commission (CAC) and most countries in Europe and the United States have limits on the residues of sulfonamides in the feed of the food industry. The Ministry of Agriculture Announcement No. 235 "Maximum Residues of Veterinary Drugs in Animal Foods" stipulates that The maximum allowable total residue in each target tissue is 100 μg / kg. The monitoring of veterinary drug residues is an important measure to ensure food safety and an important means to protect people's health.
This plan refers to the sample extraction and purification process and analysis method in the Ministry of Agriculture Announcement No. 1025-23-2008 "Determination of Sulfonamide Residues in Animal-derived Foods by Liquid Phase-Tandem Mass Spectrometry", using Shimadzu Ultra High Performance Liquid Chromatography LC -30A and triple quadrupole mass spectrometer LCMS-8030 method for the determination of nine sulfonamides in pork: sulfadiazine (SD), sulfamethazine (SM1), sulfamethazine (SM2), sulfamethoxazole Pyridazine (SMP), Sulfamethoxazole (SMZ), Sulfamethoxazole (SMM), Sulfaisoxazole (SIZ), Sulfadimethoxine (SDM), Sulfaquinoxaline (SQX). The determination scheme has fast analysis speed, good system precision and high sensitivity. The limit of quantification reaches 0.04 ～ 0.31 μg / kg, which meets the requirement of 0.5 μg / kg low limit of the Ministry of Agriculture Announcement No. 1025-23-2008.
