Veterinary drugs, including antibiotics, antiparasitics, and growth promoters, are widely used in animal husbandry. Veterinary drug residues are key issues of food safety because they arouse public concern and can seriously endanger the health of consumers. To assess the risk of veterinary drug residues in pork sold in the People’s Republic of China, the potential veterinary drug residue risks in imported and domestic pork were analyzed based on regulatory differences and veterinary drug residue safety incidents. For imported pork, a risk assessment model was established based on the differences in veterinary drug residue limits for the People’s Republic of China, Brazil, the United States, Australia, Thailand, and Russia combined with comprehensive evaluation methods. The potential risk of veterinary drug residues in U.S. pork was the highest, and that in Brazilian pork was the lowest. For domestic pork, the distribution and aggregation of veterinary drug residue safety incidents in the People’s Republic of China was analyzed from 2015 to 2019 with a geographic information system. This study provides new insights into the safety of pork on the Chinese market and a scientific basis for formulating targeted supervision and early warning strategies. [ABSTRACT FROM AUTHOR]

Aquatic products are favored by people all over the world, but the potential quality and safety issues cannot be ignored. To determine the risk of veterinary drug residues in aquatic products in the Yangtze River Delta, this study used geographic information system method to analyze Chinese veterinary drugs in aquatic products in Shanghai, Jiangsu, Zhejiang, and Anhui (Yangtze River Delta Urban Agglomerations) from 2017 to 2019. A study of the spatial distribution pattern, hot spot detection and analysis, and spatiotemporal cluster analysis of the residual excess rate and detection rate showed a random spatial distribution in the overall excess rate and detection rate of veterinary drug residues in aquatic products from 2017 to 2019. The results of hot spot analysis and spatiotemporal cluster analysis showed that the rate of detection of veterinary drug residues and the rate of detection of residues in excess of regulatory standards were clustered. This study provides a scientific basis for food safety evaluation and risk management suggestions. [ABSTRACT FROM AUTHOR]
