原标题:转基因研发单位数量不详难监管
近段时间,新疆转基因玉米违规种植让公众将目光再次聚焦在转基因问题上。前天,转基因报道研修班的媒体记者团走进吉林公主岭转基因玉米试验基地,目睹了转基因玉米从培育到进入试验农田种植的全过程。农业部相关负责人介绍,转基因作物进入农田种植要经过实验研究、中间试验、环境释放、生产性试验和获得安全证书五个阶段的递进式监管,其中任何一个环节出现问题都要立即终止,不再进入下一个阶段。
部分研发单位违规开展试验
在此次新疆被曝违规种植转基因玉米前,辽宁也被曝出现未经国家批准的转基因玉米种植,并且已渗透到当地种子销售、种植、粮食收购及市场流通等各个环节。据了解,中国目前用于加工的转基因玉米都来自进口,多用于饲料,严禁进入食品流通环节。中国目前允许进行商业化种植的只有转基因棉花和转基因木瓜,除此之外,非试验用途的转基因作物种植都是违法行为。
农业部科教司转基因生物安全与知识产权处处长林祥明介绍,我国对转基因作物的研发监管很严格,要对实验研究、中间试验、环境释放、生产性试验、安全证书五个阶段进行安全监管,其中任何一个环节出现问题都要立即终止,不再进入下一个阶段。“但是近年来确实出现了一些零星的转基因材料扩散问题,主要是研发单位,这些研发单位不仅仅是大学、科研单位,还包括一些有研发能力的企业。”林祥明说。
