Abstract:
Animal-derived agricultural products are the main source of protein for human consumption. However, veterinary drug residues in animal-derived agricultural products have gradually become one of the hot issues of food safety. In this study, China's latest veterinary drug residue limit standard GB 31650-2019 and CAC standard CX/MRL2-2018 were compared from the categories of animal derived products and veterinary drugs, the limit values of livestock products, poultry products, aquatic products and banned veterinary drugs. The results showed that 94 kinds of veterinary drugs and 1548 residue limit values were involved in the standard of GB 31650-2019, which exceeded the CAC standard CX/MRL2-2018 in quantity. However, there are still differences in the categories of veterinary drugs between GB 31650-2019 and CX/MRL2-2018, of which four and three veterinary drugs for livestock product and aquatic product prescribed by CX/MRL2-2018 are not listed in GB 31650-2019. Therefore, it is necessary to further strengthen the investigation of usage and risk assessment of these veterinary drugs in China, and promote the integration with international standards. The results of this study are helpful to understand the gap between GB 31650-2019 and CX/MRL2-2018, promote the improvement of China’s veterinary drug residue limit system for animal-derived agricultural products, and provide reference for the production and safe use of veterinary drugs in China.
