Risk analysis of veterinary drug residues in aquatic products in the Yangtze River Delta of China.
Abstract
Aquatic products are favored by people all over the world, but the potential quality and safety issues cannot be ignored. In order to determine the risk of veterinary drug residues in aquatic products in the Yangtze River Delta, this paper used the Geographic Information System (GIS) method to analyze Chinese veterinary drugs in aquatic products in Shanghai, Jiangsu, Zhejiang, and Anhui (Yangtze River Delta Urban Agglomerations) from 2017 to 2019. The spatial distribution pattern, hotspot detection and analysis and spatio-temporal cluster analysis of the residual excess rate and detection rate were studied. The results showed that the overall excess rate and detection rate of veterinary drug residues in aquatic products from 2017 to 2019 showed a spatial random distribution. The result of hotspot analysis and spatio-temporal 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 can provide a scientific basis for food safety evaluation and risk management suggestions.
