中央一号文件公布 确保安全基础上慎重推广转基因

2016-01-28 10:16:05   中国网

改革开放以来指导“三农”工作的第18份中央一号文件27日由新华社受权发布。这份文件题为《关于落实发展新理念加快农业现代化实现全面小康目标的若干意见》,全文约15000字,共分6个部分30条,包括:持续夯实现代农业基础,提高农业质量效益和竞争力;加强资源保护和生态修复,推动农业绿色发展;推进农村产业融合,促进农民收入持续较快增长;推动城乡协调发展,提高新农村建设水平;深入推进农村改革,增强农村发展内生动力;加强和改善党对“三农”工作指导。

在确保安全的基础上慎重推广转基因

文件提出,要强化现代农业科技创新推广体系建设。加强农业转基因技术研发和监管,在确保安全的基础上慎重推广。大力推进“互联网+”现代农业,应用物联网、云计算、大数据、移动互联等现代信息技术,推动农业全产业链改造升级。

转基因食品引发过敏 揭露转基因食品7大危害

近日,美国一科研机构发布了其对24名中国湖南省儿童进行转基因大米人体试验的结果,引起了国际的强烈反对。如今你走在超市里面,都很容易发现转基因食品在售卖,它们逐渐入侵我们的生活。你是否经常吃转基因食品?你知道转基因食品可能对人体产生什么危害吗?

1.营养破坏

转基因食品中的主要营养成分、微量营养素及抗营养因子的变化,会降低食品的营养价值,使其营养结构失衡。科学家们认为外来基因会以一种人们目前还不甚了解的方式破坏食物中的营养成分。

2.或不安全

未进行较长时间的安全性试验:基因化食品改变了我们所食用食品的自然属性,它所使用的生物物质不是人类食品安全提供的部份,未进行长时间的安全试验,没有人知道这类食品是安全的。

3.嗜酸性肌痛

Mayeno,A.N.等(1994)报告,发生一种新的,不明原因的病症,主要表现为嗜酸性肌痛。临床表现有麻痹、神经问题、痛性肿胀、皮肤发痒、心脏出现问题,记忆缺乏、头痛、光敏、消瘦(Brenneman,D.E.等,1993;Love,L.A.等,1993)。后查明系日本一公司生的基因化工程细菌产生的色氨酸所致。食用者在3个月后发病,导致37人死亡,1500人体部份麻痹,5000多人发生偶尔性无力。据测定,含量为0.1%便可杀死人体。

4.胃肠道问题

最令人担心的是插入到转基因大豆里的基因转移到生活在我们肠道的细菌的DNA里面去,并继续发挥作用。这意味着吃Bt玉米所造成的玉米片,会把我们的肠道细菌转变成生活着的农药制造厂,可能直至我们死为止。美国人在过去十年中,有着大幅增加的胃肠道的问题。这种大量增加,医生多认为食用转基因食品造成的。最严重的问题还不止于此。

5.过敏

在转基因操作中,含有从细菌中提取的基因的食品有可能导致过敏现象的扩展,使人发生过敏反应,特别是对儿童,孕妇和具有过敏体质的成人。比如:科学家将玉米的某段基因加入到大豆、小麦和贝类动物的基因中,蛋白质也随基因加了进去,那么,以前吃玉米过敏的人就可能对这些大豆、小麦和贝类食品过敏。

6.心脑血管疾病

这些转基因大豆里,被他们的生物科学家植入了饱和脂肪基因。这些基因导致转基因大豆生产出来的豆油,在进入人体以后,会形成大量的饱和脂肪,增加了血液的血粘稠度,为脂肪肝、高血脂、脑血栓等重大心脑血管疾病埋下了慢性定时炸弹。

7.引发新疾病

转基因技术采用耐抗菌素基因来标识转基因化的农作物,这就意味着农作物带有耐抗菌素的基因。这些基因通过细菌而影响我们。英国的研究显示,转基因作物中的突变基因可能会进入到生物体内,其结果可能会导致新的疾病。如果类似结果发生在人和动物体内,就可能培养出功效最强的、抗菌素也无法杀死的超级细菌。
