掌握不同国家、地区猪肉中农药最大残留限量（Maximum Residue Limits，MRL）要求现状，分析其差异性，以便降低猪肉贸易风险。收集我国和主要贸易国家，联合国粮农组织食品法典委员会（Codex Alimentarius Commission，CAC）、澳大利亚、美国、日本、新西兰、欧盟现行的猪肉农药MRLs标准和技术法规进行对比分析。由于各国饮食习惯、膳食结构不同，我国与主要贸易国家之间存在农药MRL差异，主要表现在：部分农药残留物的定义中所包含的农药转化物、代谢物、反应产物等的不同；农药最大残留限量指标数量和品种的不同，其中我国与欧盟、日本和澳大利亚等国在指标数量上差异较大；相同农药残留限量指标的宽严程度不同，个别指标差异较大。我国应继续加强国际间猪肉农药残留限量标准制定交流，进一步完善我国猪肉农药残留限量标准体系。

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.
