广东省部分地区市售水产品中氯霉素残留情况调查

Investigation of chloramphenicol residues in aquatic products in several areas of Guangdong Province

目的调查广东省7个城市市售水产品中氯霉素的残留情况,为监管部门提供参考依据,为消费者提供消费指导。方法按照GB/T 22338—2008《动物源性食品中氯霉素类药物残留量测定》中高效液相色谱-串联质谱法对采集的水产品中氯霉素的残留情况进行检测。结果检测的150份水产品样品中氯霉素的检出率为11.33%（17/150）。7个城市市售的水产品分别都检出氯霉素,检出率为5.00%~20.00%。不同种类的水产品间比较,软体类的检出率较高（36.00%,9/25）,甲壳类的检出率较低（5.56%,1/18）。结论广东省部分地区市售水产品中存在氯霉素残留,具有一定的食品安全隐患,应该引起重视。

Objective To investigate the chloramphenicol residue in aquatic products in 7 cities of Guangdong Province,provide reference for regulation and guidance for the consumers.Methods According to the national standard GB/T22338-2008,chloramphenicol residues in aquatic products were determined by HPLC-MS/MS.Results The detection rate of chloramphenicol in total 150 samples was 11.33%（17/150）.Unqualified samples could be found in every city.The detection rates of chloramphenicol in the aquatic products from different cities were from 5.00% to 20.00%.Compared by the species,molluscs had the highest detection rate of 36.00%（9/25）.Crustaceans had the lowest detection rate of 5.56%（1/18）.Conclusion Chloramphenicol residues were found in aquatic products in Guangdong Province,which may cause food safety problems and was worthy of attention.
