摘要
利用高效液相色谱-串联质谱方法,分析2016年我国15个地区、604份猪肉样品中16种磺胺类药物的残留特征。结果表明:猪肉样品中磺胺类药物的检出率为4.80%,超标率为1.66%;磺胺类药物残留以磺胺二甲嘧啶为主,磺胺氯哒嗪次之;样品中磺胺二甲嘧啶的检出量高达321.0μg/kg。我国猪肉中磺胺类药物的残留特征与畜禽养殖粪便中的情况基本一致,磺胺类药物中磺胺二甲嘧啶的检出率和残留量均较高,同时也存在其他磺胺类药物残留。
Sixteen sulfonamide residues in 604 pork samples collected from 15 Chinese provinces in 2016 were investigated by using ultra performance liquid chromatography combined with tandem mass spectrometry (UPLC-MS/MS). The detection rate and over-limit rate of sulfonamides were 4.80% and 1.66%, respectively. Sulfamethazine was the dominant residual sulfonamide at a maximum concentration of 321.0 μg/kg, followed by sulfachloropyridazin. The residual characteristics of sulfonamides in pork and livestock and poultry feces were consistent. Besides sulfonamide, other sulfonamide residues were also detected in pork samples.
