Abstract:In order to reduce the risk of pork trade, the current status of the maximum residue limits (Maximum Residue Limits, MRL) of pesticides in pork in China and abroad was studied, and the differences were examined. Current pork pesticide MRL standards and technical regulations of of the Codex Alimentarius Commission (Codex Alimentarius Commission, CAC), Australia, USA, Japan, New Zealand, European Union and China were collected for comparative analysis. Due to different dietary habits and diet structures, there are differences in pesticide MRL standards between China and major trading countries, which are mainly reflected in: Differences in pesticide transformants, metabolites, reaction products, etc. included in the definition of some pesticide residues; Differences in the number and type of maximum pesticide residue limit (MRL) indicators, among which China is quite different from EU, Japan and Australia; Differences in degrees of leniency and strictness, with quite large differences some individual indicators. China should continue to strengthen the international communication on pork pesticide residue limits and further improve the standard system for pork pesticide residue limits.
