CAC关于兽药最大残留限量在不同动物间外推的方法及示例

Extrapolation Approaches and Examples of Maximum Residue Limits for Veterinary Drugs to One or More Species by CAC

兽药最大残留限量(MRL)在不同动物间的外推最早是通过讨论不同有鳍鱼类间外推而提出的,后来延伸到反刍动物间、非反刍哺乳动物间、禽类间的外推等。2021年国际食品法典兽药残留委员会(CCRVDF)第25届会议讨论了兽药MRL在不同动物间的外推方法,国际食品法典委员会(CAC)第44届会议同意并采纳了这一方法。兽药MRL外推对世界各国尤其是发展中国家建立本国限量标准,保护公共健康和促进贸易有着十分重要的意义。本文就CAC关于兽药MRL在不同动物间外推的术语定义、方法和示例、限量标注等内容进行介绍,以期推动我国兽药MRL的科学制定。

The proposal on extrapolation of MRL for veterinary drugs to one or more species was initiated by a discussion considering extrapolation of MRL for fish species,then for the ruminants,for the non-ruminant mammals and for the birds(poultry).The extrapolation approaches of MRL were discussed and proposed by CCRVDF25,then were agreed and adopted by CAC44 in 2021.The extrapolation of MRL was of great importance because of the extraordinary opportunity that it presented to countries,particularly developing countries,to develop their respective MRL standards through extrapolation to protect public health and enable trade.This paper outlines the main contents of the note on terminology,approaches,examples and appropriate symbol of extrapolation of MRL for veterinary drugs to one or more species.
