摘要
目的 :了解成都地区动物性食品中兽药残留水平 ,探讨其污染来源 ,评价其膳食安全性。方法 :采用分层多级整群随机抽样 PPS(按容量比例概率抽样 )确定 ,高效液相色谱法测定样品 ,测定结果依 GB16 86 9— 2 0 0 0及最大允许限量 (MRL )和日允许摄入量 (ADI)评价。结果 :氯霉素、呋喃唑酮、喹乙醇、林可霉素、四环素类、磺胺类等 18药物均被检出 ,总阳性检出率为 8.387% ;残留量最高为 2 1.32 0 (金霉素 ,猪肝 ) ,最低为 0 .0 2 3mg/ kg(磺胺 ,鸡肉 )。其中 ,林可霉素、氯霉素、四环素类阳性检出率分别为 8.0 0 %、1.71%和 6 .85 7% ;其阳性超标率分别为 92 .86 %、10 0 %和 73.91%。磺胺类阳性检出率为 12 .5 86 % ;呋喃唑酮检出率为 8.84 9% ;喹乙醇检出率为 5 .30 9%。其阳性超标率分别为 85 .71%、90 .0 0 %和 83.33% ;城乡牛肉、鸡肉中林可霉素残留量分别达到 MRL 10 .2 2倍、12 .8倍、12 .4 3倍和 2 8.2倍 ;城乡猪肉中土霉素、金霉素残留量分别达到 MRL的14 .5 8倍、11.3倍、5 .4倍和 2 .4倍 ;城市牛肉、猪肉、鸡肉中甲氧苄啶残留量分别达到 MRL的 8.75倍、1.3倍和 1.4倍 ,农村牛肉、猪肉、鸡肉中甲氧苄啶残留量分别达到 MRL的 3.7倍、6 .6倍、4 .5倍 ;城乡猪肉、猪肝中喹乙醇残留量分别达到 MRL的
Objective:To investigate the residual level and polluted source of veterinary drugs in animal derived food in Chengdu,and to assess its dietary reliability.Methods:Investigation points were decided according to probability proportional sampling Probability Proportional to Size(PPS).Samples were detected with high performance liquid chromatography(HPLC),results were assessed by using GB16869-2000,Maximum Residue Limit(MRL) and Acceptable Daily Intake(ADI).Results:18 kinds of veterinary drugs such as Linconmycin,Chloramphenicol,Etracychine,Furazotidone Sulfonamids and Olapuindox were detected.Total positive rate was 8.39%;maximum and minimum residual volumes were 21.32 mg/kg(Chlortetracycline in pork liver) and 0.023mg/kg(Sulfanilamide in chicken meat) respectively.Positive rates were 8.00%,1.71% and 6.86% on Lincomycin,Chloramphenicol and Etracycline respectively,ultra-standard rates were 92.86%,100% and 73.91% respectively.Positive rates were 12.59%,8.85% and 5.31% on Sulfanilamide,Furazolidone and Olapuindox respectively,ultra-standard rate were 85.71%,90.00% and 83.33% respectively.The residual volumes of Lincomycin in beef and chicken were 10.22 and 12.8 times of MRL in city,12.43 and 28.2 times in countryside.Oxytetracycline and Chlortetracycline in pork were 14.58 and 11.30 times of MRL in city,5.40 and 2.40 times in countryside.Trimethoprimum in beef,pork and chicken was 8.75,1.30 and 1.40 times of MRL respectively in city and 3.70,6.60 and 4.50 times respectively in countryside.Olapuindox in pork and pork liver was 6.25 and 0.50 times of MRL in city,8.97 and 4.50 times in countryside.Total dietary intakes with Lincomycin Etracycline,Oxytetracycline,Chlortetracycline and Sulfaquinoxaline were below ADI in urban and rural residents.The levels of intakes with Linconmycin etracycline,Oxytetracycline,Chlortetracycline and Sulfaquinoxaline were 15.57%,25.44%,93.49%,30.59%,0.16% ADI in urban residents and 11.72%,22.78%,56.78%,21.78% 2.00% in rural residents respectively.Conclhsipn:Pollution of veterinary drugs expecially drugs of Tetracyclines and Sulfonamides in animal derived food is very serious.So corresponding control strategy should be adopted.
