英文摘要:

      Objective To investigate the quality and safety status of commercially available aquatic products in Guangzhou in 2018?2019, and analyze the residues of chloramphenicol, malachite green, furazolidone and formaldehyde in aquatic products. Methods The residues of aquatic products chloramphenicol, malachite green, and furazolidone were qualitatively tested by colloidal gold rapid detection method. According to SC/T 3025-2006 Standards for fishery industry of the People’s Republic of China-Determination of formaldehyde in aquatic products (First method Spectrophotometric method) and combined with literature method, the qualitative and quantitative detection of formaldehyde in aquatic products was carried out. Results A total of 30 samples of 200 aquatic products were found containing illegal drug residues, with a total detection rate of 15.0%. Among them, chloramphenicol was detected in 5 cases, with the detection rate of 2.5%, malachite green in 3 cases, with the detection rate of 1.5%, furazolidone in 10 cases, with the detection rate of 5.0%, and formaldehyde in 13 cases, with the detection rate of 6.5%. In addition, chloramphenicol and malachite green residues were detected in 1 sample. Furazolidone detection rate was mainly concentrated in fish and shrimp. Conclusion Some aquatic products are contaminated with chloramphenicol, malachite green, furazolidone and formaldehyde. The relevant departments should strengthen the supervision and administration in the process of aquaculture, transportation and marketing of aquatic products.
