德国多家科研机构进行的一项研究发现，基因可能通过食物链在不同物种之间转移。研究人员用转基因玉米制成颗粒饲料喂养实验动物，结果发现这些动物的肌肉和器官里都存在玉米的遗传物质 DNA片断。 科学家目前还没有在实验动物体内发现具有完整功能的转基因玉米 DNA序列
A study conducted by several German research institutes found that genes may be transferred between different species through the food chain. Researchers fed GM animals with pelleted feed and found that DNA fragments of maize genetic material were found in the muscles and organs of these animals. Scientists have not yet found a fully functional transgenic corn DNA sequence in experimental animals
