市售猪肉盐酸克仑特罗残留卫生学调查与卫生监督探讨

A Hygiene Investigation and Health Inspection Research on Clenbuterol Residual of Pork(Including Entralils)

目的 了解中山市市售猪肉 (含猪内脏 )盐酸克仑特罗残留现状 ,提出卫生监督的要点。 方法 采用分层按比例随机抽样的方法 ,在全市肉菜市场以购买方式共抽取 80份市售猪肉 (含猪内脏 ) ,采用气相色谱 /质谱仪联用法(GC/MS)对抽检样品中盐酸克仑特罗残留进行检测 ,同时对市售猪肉的来源进行卫生学调查 ,提出预防控制措施。 结果 80份样品中盐酸克仑特罗阳性检出率为 5 % ,盐酸克仑特罗阳性样品全部来自一个镇区 ,其它镇区均未检出阳性样品。 结论 中山市市售猪肉 (含猪内脏 )中存在盐酸克仑特罗残留 ,但阳性率较低 ,且只在一个区域内检出 ,检出的阳性样品全部为猪内脏 ,猪肉样品阳性检出率为 0 ;非正规渠道进货样品的阳性检出率明显高于正规渠道进货样品。建议将盐酸克仑特罗在动物体内的残留列为常规食品卫生检测项目 ,制定相应的卫生标准。

Objective To get the message of Clenbuterol residual of pork(including entralils) and to recommend health inspection measures. Methods Using stratified random proportional sampling,80 samples of pork(including entrails) were selected from Zhongshan city and the Clenbuterol residual of sample were detected by gas chromatography/mass spectrometry(GC/MS),meanwhile, investigating the source of the pork to recommend control and prevention measures. Result The positive rates of Clenbuterol were 5% in 80 samples, all postive Clenbuterol samples were from one township,no positive samples were found in other townships. Conclusion There had Clenbuterol residual in pork of Zhongshan city,but postive rates were very low and Clenbuterol residual had detected only in one area,all positive samples were entralils,the positive rates in pure muscle were zero. Clenbuterol residual should be included into common food hygiene inspection, corresponding standard should be made,and the administration to positive pork suppliers should be strengthened.
