主题：【原创】方舟子与转基因的安全 -- 花大熊

我很奇怪看完那个关于美国FDA转基因标注链接的人还能得出这么一个结论。

FDA够支持转基因的了，但是看看人家怎么说为什么不建议用GMO-Free的：

The term "GMO free" may be misleading on most foods, because most foods do not contain organisms (seeds and foods like yogurt that contain microorganisms are exceptions). It would likely be misleading to suggest that a food that ordinarily would not contain entire "organisms" is "organism free."

为什么不能用Free呢？因为人家说现在还没有一个标准来定义什么叫free：

Consumers assume that "free" of bioengineered material means that "zero" bioengineered material is present. Because of the potential for adventitious presence of bioengineered material, it may be necessary to conclude that the accuracy of the term "free" can only be ensured when there is a definition or threshold above which the term could not be used. FDA does not have information with which to establish a threshold level of bioengineered constituents or ingredients in foods for the statement "free of bioengineered material."

转基因=GMO？看看FDA怎么说的：

Consumers also expressed some preference for the term "biotechnology" over such terms as "genetic modification" and "genetic engineering" (Ref. 1).

人家只不过是不建议你用GM或者GMO来代表转基因技术而已，但是你可以用biotechnology或者Genetically engineered来代表转基因。

下面是FDA建议的非转基因食品的标注：

"We do not use ingredients that were produced using biotechnology;"

"This oil is made from soybeans that were not genetically engineered;" or

"Our tomato growers do not plant seeds developed using biotechnology."

请问你咋得出美国FDA不允许标注非转基因食品这个结论的？
