目的动物源产品中β-兴奋剂残留状况与防控分析。方法应用气质联用法对生猪尿液、毛发和肝脏中克伦特罗、莱克多巴胺、沙丁胺醇、西马特罗和特步它林等5种常见β-兴奋剂进行定性定量分析,从残留结果分析β-兴奋剂的使用状况。结果在215份检测样品中,检出克伦特罗、沙丁胺醇和莱克多巴胺等3种β-兴奋剂,未检出西马特罗、特步它林,阳性率为16.7%,尿样、肝脏和毛发中阳性率分别为16.3%、17.4%和16.7%,存在克伦特罗、莱克多巴胺和沙丁胺醇混合使用、用量和用期混乱现象。结论违法使用现象屡禁不止,建立完善的兽药残留监控体系,对动物源产品进行全程监控,确实遏制β-兴奋剂的使用,保障食品安全。
Purpose β-agonist residues in animal-derived products and control analysis. Methods Qualitative and quantitative analysis of 5 common β-agonists such as clenbuterol, ractopamine, salbutamol, cimaterol and Xtepiride in urine, hair and liver of pigs was carried out by gas chromatography-mass spectrometry (GC-MS / MS) - the use of stimulants. Results Among the 215 samples tested, three kinds of β-agonists such as clenbuterol, salbutamol and ractopamine were detected. Cimicrin and Xtepirole were not detected, the positive rate was 16.7%. Urine samples, liver and The positive rates of hair were 16.3%, 17.4% and 16.7%, respectively. There was a combination of clenbuterol, ractopamine and salbutamol, the dosage and the period of chaos were mixed. Conclusion The phenomenon of illegal use has been repeatedly banned. The establishment of a complete veterinary drug residue monitoring system to monitor animal products throughout the country and indeed curb the use of β-agonists to ensure food safety.
