闽南地区食源性动物组织中黄曲霉毒素B_1残留量调查研究

Investigation of aflatoxin B_1 residues in foodborne animal tissue in minnan region

应用酶联免疫吸附(ELISA)技术对闽南地区食源性动物的鸡、鸭、猪肝脏和肌肉组织以及国外进口猪肌肉组织中的黄曲霉毒素B_1(AFB_1)残留量进行抽样检测。结果显示猪肉猪肝黄曲霉毒素B_1检出率100%,鸡肝65%、鸭肝75%,但都末超过限量标率;猪肝中AFB_1含量最高,显著高于猪肌肉和鸡、鸭肝中AFB_1含量(P<0.01);而鸡、鸭肝中的AFB1含量无显著性差异(P>0.05);此外,国外进口猪肉中AFB1虽未超标,但也存在AFB_1污染问题。调查结果表明,食源性动物组织中黄曲霉毒素B1残留问题普遍存在。

Enzyme-linked immunosorbent （ELISA） technique was used to detect the aflatoxin B1 residual quantity in livers and mus-cles of foodborne animals which contain chicken, duck and pig in minnan region.In addition ,imported pigs were also detected.The re-suLts show that aflatoxin B1 detectable rate in pig livers and muscles were 100%,but 65% in chicken liver and 75% in duck liver, which all didn＇t exceed the national limited standard. The highest of AFB1 content was tested in pork liver, significantly higher than pig muscles , chicken livers and duck livers （P〈0.01）; AFB1 contents in chicken and duck liver were no significant difference （P 〉0.05）. Besides that , AFB1 residues in imported pork though not overweight but also exist AFB1 pollution phenomenon. The resuLt of AFB1 Investigating of foodborne animal tissues suggested that problem of contamination of AFB1 has become widespread.
