江苏省泰州市部分市售鸡蛋黄曲霉毒素B1污染状况调查

Investigation on Afl atoxin B1 Residues in Chicken Eggs Sold in Taizhou City,Jiangsu Province

为了解江苏省泰州市市售鸡蛋中黄曲霉毒素B1(AFB1)的污染情况,2020年采集不同超市、集贸市场的60个种类/批次的鸡蛋各30枚,每个种类/批次随机选取3枚,共180枚,采用商品化酶联免疫吸附试验(ELISA)试剂盒进行AFB1残留量测定。结果显示:在抽检的180枚鸡蛋样品中,15枚样品中有一定的AFB1残留,为0.20~0.64μg/kg,占8.33%,均为超市中不同场家产品,而集贸市场的鸡蛋(多为散养鸡所产)中AFB1残留量都很低。因此,规模化养殖场在蛋鸡饲养过程中要严格把控饲料质量,定期对饲料做好检测和监测。
