An Investigation of Lead Content in Preserved Eggs Sold in Huaihua

为了解怀化市市售皮蛋中铅含量情况,采集了怀化辖区内传统配方工艺皮蛋和新型配方工艺皮蛋两大类皮蛋制品,采用GB5009.12-2010规定的石墨炉原子吸收分光光度法测定,并根据GB2762-2017所规定限值进行评价.检测结果发现,新型配方工艺皮蛋中铅含量合格率为100%,传统配方工艺皮蛋中铅含量合格率为90.9%;商场超市售卖皮蛋铅含量合格率为100%,农贸市场售卖皮蛋合格率为90.9%.可见怀化市市售皮蛋类食品中铅暴露水平总体看较好,其中新型配方工艺皮蛋类抽样检查均符合国标,传统配方工艺皮蛋类铅含量个别存在超标现象.建议有关部门持续加强对传统配方工艺皮蛋的管理与监察力度,确保食品安全.
