中文摘要:

      目的 对氟苯尼考(florfenicol, FFC)在鸭蛋中的残留情况做初步的调查研究。方法 针对浙江南部、福建北部、广东南部、湖北中部、江西东部、河南东部的六大区域的鸭蛋采用GB/T 22338-2008 《动物源性食品中氯霉素类药物残留量测定》规定的方法进行氟苯尼考的药残检测。结果 标准曲线相关系数为: r=0.9996, 方法准确。以该方法测定每个地区6组鸭蛋样品, 6组咸鸭蛋样品, 共计12组样品, 其中以河南东部出产的鸭蛋为原料制成的咸鸭蛋检出氟苯尼考残留量为: 1.44 μg/kg, 其余样品未检出。结论 氟苯尼考在鸭蛋中会造成一定程度的残留, 仍需通过严格的养殖现场管理控制用药, 并且通过鸭蛋的定期抽检来监测指标的变化。

英文摘要:

      Objective To investigate the residues of florfenicol (FFC) in duck eggs. Methods Flubenicol residues were detected in duck eggs from six regions: southern Zhejiang, northern Fujian, southern Guangdong, central Hubei, eastern Jiangxi and eastern Henan. The method specified in GB/T 22338-2008 Determination of Chloramphenicol Residues in Food of Animal Origin was adopted. Results The correlation coefficient of standard curve was r=0.9996, and the method was accurate. The method was used to determine 6 groups of duck eggs and 6 groups of salted duck eggs in each area. Among 12 groups of samples, the residue of florfenicol in salted duck eggs made from duck eggs from Eastern of Henan was 1.44 μg/kg, while the rest of the samples were not detected. Conclusion Flufenicol can cause residues in duck eggs to a certain extent. It is still necessary to control the use of drugs through strict management of the farming site, and monitor the changes of indicators through regular sampling of duck eggs.
