摘　　要：近20年来,转基因作物的种植面积持续增加,转基因产品的流通量和流通速度呈迅速上升趋势。在不同国家与地区间,非转基因产品内出现低含量转基因成分的问题,即转基因成分低水平混杂日趋严重。以此问题为立脚点,比较全面的阐述了7个不同国家与地区(组织)的转基因成分低水平混杂的定义,分析了共同特点;总结了各国的现行政策与允许值的规定;概述了低水平混杂问题对进出口贸易方面产生的影响,旨为我国制定低水平混杂的相关政策及检测标准提供基础资料。Over the last two decades, the land area under cultivation with genetically modified organisms （ GMOs ） has been growing steadily, and the amount and speed of circulation of many GM products in international trade tend to be rising. The issue that low content of GMO in non-GM product occurred in different countries and regions, i.e., low level presence （ LLP ） of transgenic components has been increasingly serious. Considering this issue, this article expounds the definitions of LLP in seven different countries and regions （ organizations ）, and analyzes the common characteristics ; then summarizes the current policies in every country, the threshold of LLP, and the effects of LLP on import and export trade. This study would provide the basic information for the relevant policies and detection standards for China.
