Veterinary drug residues in freshwater products sold in Shenzhen, 2014–2018

Abstract

Objective To monitor the veterinary drug residues of the freshwater products in Shenzhen from 2014 to 2018, we analyze the over–standard conditions and the trend of change year by year, master the safety risk status of the freshwater products, and provide scientific basis for the regulators to carry out food safety risk monitoring.

Methods The methods of detecting the veterinary drug residues is basis on GB/T 19857–2005, GB/T 22338–2008, SC/T 3019–2004, SN/T 0197–2014, GB/T 21311–2007, GB/T 21312–2007. And 20 kinds of veterinary drugs residues of the freshwater products are analyzed in different year, species, sampling districts and sampling sections.

Results A total of 79 out of 610 freshwater products were over–standard, with an over–standard rate of 12.95%, of which the highest rate exceeded the standard rate of 28.00% in 2015, the difference was statistically significant ( P<0.01). Among the different species of veterinary drugs, the highest rate of Malachite green exceeded 5.90%, the difference was statistically significant ( P<0.01).Among different sample categories, the highest rate of raw fish exceeded 35.71%, the difference was statistically significant ( P<0.01). There was a significant difference in the excess rate of veterinary drug residues inthree different sampling sections ( P<0.05).

Conclusion There are some veterinary drug residues of freshwater products in Shenzhen. To ensure food safety, it is urgent to strengthen the monitoring of veterinary drug residues in freshwater products, regulate the processes of breeding, transportation, processing, storage and sales, prohibit the use of illicit drugs and reduce the use of veterinary drugs.
