Abstract: 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.
