摘　　要：目的了解广州市市售水产品鱼类中孔雀石绿及结晶紫的残留情况,为监管部门提供参考依据,为广大消费者提供消费指导。方法按GB/T 19857—2005《水产品中孔雀石绿和结晶紫残留量的测定》对所采集的鱼类样品中孔雀石绿及结晶紫的残留情况进行检测。结果检测的120份鱼类样品中孔雀石绿及其代谢物的检出率为6.67%(8/120)、结晶紫及其代谢物的检出率为0.83%(1/120),两者在淡水鱼中的检出率为8.91%(9/101),近海鱼中的检出率为0%(0/19)。不同种类养殖鱼间比较,桂花鱼的检出率最高,达40%(2/5)。结论广州市市售鱼类中存在孔雀石绿及其代谢物和结晶紫及其代谢物残留的情况,值得关注。Objective To investigate the malachite green and crystal violet residues in fishes in Guangzhou City,provide reference for regulation,and provide guidance for the consumers. Methods According to the national standard GB / T19857- 2005,the residues of malachite green and crystal violet in fish samples were determined. Results The detection rate of malachite green and its metabolite in total 120 fish samples was 6. 67%（ 8 /120）,and that of crystal violet and its metabolites was 0. 83%（ 1 /120）. The detection rate of the forbidden drug in freshwater fishes was 8. 91%（ 9 /101）,while 0%（ 0 /19） in sea fishes. Compared by the species,osmanthus fish had the highest detection rate of 40%（ 2 /5）.Conclusion Malachite green and crystal violet and their metabolites residues were found in commercial fishes in Guangzhou,which was worthy of attention.
