农业部回应转基因食品致癌让精子活力下降:谣言

2016-04-14 04:01:07   京华时报

京华时报讯(记者文静)昨天,农业部召开发布会,权威回应转基因领域几大焦点问题。农业部科技教育司司长廖西元表示,目前,我国批准种植的转基因作物只有棉花和番木瓜,从生产和消费实践看,经过科学家安全评价、政府严格审批的转基因产品是安全的。

中国工程院院士、国家农业转基因生物安全委员会主任委员吴孔明在发布会上表示,近期,网上传播的转基因识别指南里面很多东西没有科学依据,基本上都是随意编造。

吴孔明说,在我们国家随着转基因这一块的应用,出现了非常多的我们认为是不科学的东西,有的也可能成为谣言。比如转基因玉米和大豆会导致癌症,转基因玉米导致广西大学生精子活力下降,转基因食品导致不育,欧美人不吃转基因食品,转基因马铃薯致实验大鼠中毒,转基因玉米导致老鼠减少、母猪流产,转基因正成为超过原子弹的杀伤武器。有很多这样和那样的,我们准确地说不符合实际、也不符合科学的说法。其实是谣言,这些都是毫无事实依据,也被科学界一一否定。

此外,农业部科技教育司司长廖西元也明确提到,通过安全评价审批的转基因产品是安全的,并给出推进转基因作物产业化路线图。

他说,首先要严格按照法律法规开展安全评价和安全管理,获得生产应用安全证书。其次是按照非食用、间接食用和食用的路线图,要先发展非食用的经济作物,然后是饲料作物、加工原料作物,接着是一般食用作物,最后是口粮作物。第三充分考虑产业的需求,重点解决制约我国农业发展的,比如抗病、抗虫、节水抗旱、高产优质等瓶颈问题。

□焦点1

转基因作物不能从外形判断

近期网络上转发过一篇“转基因识别指南”涉及到粮油蔬菜水果数十种,对此,吴孔明表示,任何一种农作物从它的自然分布的遗传多样性而言,各种各样的品种都有,但是它是自然存在的,不能因为我们过去没有见过,就把它编成所谓的“转基因的鉴别方法”,这是没有科学依据的。

吴孔明表示,转基因产品分成两类:一类是我们自己种植和生产的,到目前为止我们国家只批准转基因抗虫的棉花和转基因抗病毒的番木瓜两个农作物商业化应用。另外一类是我们从国外进口的,目前我国进口的转基因食品有大豆、玉米、油菜、棉花(纤维)。

因此,目前在我国市场上流通的转基因的相关产品,就是我们批准种植的和批准进口的这几个作物,其他是没有的。网上传播的小麦、水稻和番茄、大蒜、洋葱、紫薯、土豆、彩椒、胡萝卜等,其实都不是转基因品种。转基因不是从外形判断的,只能基因鉴别。有人说一些西红柿形态发生变化,但不能就此判定为转基因。

□焦点2

严格审批的转基因产品是安全的

廖西元介绍,转基因技术产生以来,为保障转基因产品安全,国际食品法典委员会、联合国粮农组织、世界卫生组织等制定了一系列转基因生物安全评价标准,成为全球公认的评价准则。依照这些评价准则,各国制定了相应的评价规范和标准。

从科学研究上讲,众多国际专业机构对转基因产品的安全性已有权威结论,就是通过批准上市的转基因产品都是安全的。从生产和消费实践看,20年转基因作物商业化累计种植近300亿亩,至今未发现被证实的转基因食品安全事件。因此,经过科学家安全评价、政府严格审批的转基因产品是安全的。
