转基因水稻危害

怎这样呢

LLRICE601在06年当年就被deregulation了，放狗一搜就有。所谓的污染是指导致了相邻忽悠有钱人的有机农场出的米无法通过有机认证，真要是什么大麻烦就赔29万美元？06年的案子到现在还是“进行时”么？

另外，LZ要是多有一点生物学知识就应该知道，RNA层面的调控可以控制特定基因的表达水平，但是不可能让生物体表达一种全新的蛋白。研究RNA的目的，无非是让已经已有的转基因作物所转的基因能够更加有效/可控的表达出来。

怎这样呢

种畜也不是养到老死吧？ 是不是有机食品我不知道，不过我倒是真知道欧洲不少养殖场种畜不喂转基因是真的 ...

这里讨论的是转基因玉米已经在种畜上安全的使用了很多代，跟欧洲有没有“养殖场种畜不喂转基因”有什么关系？

况且，奶牛厂不存在专门的种畜一说，所有奶牛都是在不停的产仔-挤奶循环。用冷冻精子人工授精，生下来的小牛，母的继续养作奶牛，公的当肉牛养或者养大一点杀掉当小牛肉卖。我没有功夫去查美国有多少奶牛场不用转基因玉米，但可以明确地说转基因玉米已经在奶牛上已经长期广泛使用而没有任何安全问题。

此外澄清一点，美国的有机产品是允许有转基因成分的，我在二楼的回复没有说清楚，受影响的有机农场在美国仍然能够通过有机认证，但是不能当作有机大米出口到其他不给转基因产品有机认证的国家。

怎这样呢

真是谣言信口就来啊，“美国的有机产品是允许有转基因成分的”， 看看USDA怎麼說的， http://blogs.usda. ...

呵呵 说归说，咱们来看看官方对于受LLRICE601影响的有机产品是怎么做的吧

http://www.i-sis.org.uk/LLRICE601.php

“USDA wants organic farmers to turn a blind eye to transgenic contamination

USDA is the final authority on organic certification in the US. But it is taking steps to undermine this standard, as is clear from the USDA/APHIS draft environment assessment of LLRICE601 on behalf of Bayer [4]: “The presence of a detectable residue of a product of excluded methods alone does not necessarily constitute a violation of the National Organic Standards.” In practice, planting genetically-modified seed would render the organic crop non-organic and require it to be sold as conventional. But the USDA/APHIS goes on to state: “The status of the organic operation depends on the operator’s foreknowledge of the origin and status of the seed planted.” In other words, what the operator does not know, does not count. So organic farmers are encouraged to maintain their ignorance. Unfortunately, their customers do not hold the same view.”

明白了吧，只要生产者不知情，统统不算数哦。反正消费有机产品的冤大头们也不会察觉到底是不是真有机

怎这样呢

真有你的， 是以USDA为准还是以一个NGO 的评论为准？

本段话里面引用的USDA原文你视而不见了？

喜欢USDA的话咱贴段原始报告出来打脸
http://www.aphis.usda.gov/brs/aphisdocs/06_23401p_pea.pdf

The National Organic Program (NOP) is administered by USDA's Agricultural
Marketing Service (AMS). Organic production operations must develop and maintain an
organic production system plan approved by their accredited certifying agent in order to
obtain certification. Organic certification of a production or handling operation is a
process claim, not a product claim. Organic certification involves oversight by an
accredited certifying agent of the materials and practices used to produce or handle an
organic agricultural product. Oversight by a certifying agent includes an annual review of
the certified operation's organic system plan and on-site inspections of the certified
operation and its records.
红字翻译：对于“有机”生产或者过程的认证是基于其生产过程和处理方式，而非产品本身。

The organic system plan enables the production operation to achieve and document
compliance with the National Organic Standards, including the prohibition on the use of
excluded methods. Excluded methods include a variety of methods used to genetically
modify organisms or influence their growth and development by means that are not
possible under natural conditions or processes. Although the National Organic Standards
prohibit the use of excluded methods, they do not require testing of inputs or products for
the presence of excluded methods, unless a certifying agent has reasonable suspicion that
a prohibited substance or excluded method was used. The presence of a detectable
residue of a product of excluded methods alone does not necessarily constitute a violation
of the National Organic Standards. Planting of genetically-modified seed would render
the organic crop non-organic and require it to be sold as conventional. The status of the
organic operation depends on the operator's foreknowledge of the origin and status of the
seed planted. The duty of an organic grower to develop and maintain an organic
production system that meets the relevant regulatory standards will not change regardless
of which alternative is selected. Therefore, granting the extension of nonregulated status (alternative C) will have no significant impact on organic farming. Likewise there will be
no significant impact from alternatives A and B.

红字：（在有机产品中）仅仅是含有非有机产品的残留并不一定违反有机条例（National Organic Standards）。使用转基因种子会导致organic crop（注意前文，organic crop此处指用有机方式种植的作物）只能作为普通作物出售。“有机”生产方式取决于生产者事先知晓其所种植的作物的背景和状况。

“有机”认证的不是产品而是过程，够赤裸裸了吧？

怎这样呢

你是欺负这里有人不懂英文故意胡搅蛮缠吧？

这里的英文很清楚， 所谓PROCESS,  包括不能使用任何转基因 ...

我说允许有转基因成分到你这里就变成允许转基因？你自己不是说清楚了么，无意被污染的有机产品在整改期间内可以照常上市，难道不就是允许有转基因成分的有机产品么？谁在胡搅蛮缠？

怎这样呢

此外，美国的有机认证主要检查的生产过程（包括你说提到的不能使用转基因种子）而不是产品，这实际上是给被转基因花粉污染的有机产品开后门，大多数情况下这种污染根本不会有人察觉。
