In 2009, countries that grew 95% of the global transgenic crops were the United States (46%), Brazil (16%), Argentina (15%), India (6%), Canada (6%), China (3%), Paraguay (2%) and South Africa (2%).[14] The Grocery Manufacturers of America estimate that 75% of all processed foods in the U.S. contain a GM ingredient.[32] In particular, Bt corn, which produces the pesticide within the plant itself, is widely grown, as are soybeans genetically designed to tolerate glyphosate herbicides. These constitute "input-traits" are aimed to financially benefit the producers, have indirect environmental benefits and marginal cost benefits to consumers.
看看这段
Coexistence and traceability
The United States and Canada do not require labeling of genetically modified foods.[54] However in certain other regions, such as the European Union, Japan, Malaysia and Australia, governments have required labeling so consumers can exercise choice between foods that have genetically modified, conventional or organic origins.[55][56] This requires a labeling system as well as the reliable separation of GM and non-GM organisms at production level and throughout the whole processing chain.[55][56]
还有这段，都有详细来源的可信文字表述。

BBC 的文章称，“一些国家仍然坚决反对转基因作物的种植，认为它们最终有可能会破坏生物多样性及自然抗病虫害的能力，而且很难阻止他们与非转基因作物进行交叉授粉。意大利表示，它反对欧盟的决定。‘对欧洲公民和整个环境来说，这是糟糕的一天。’国际环保组织地球之友这样表示。该组织称，Amflora土豆‘带有一种争议性的抗耐药性基因，它不能保证不会将进入食物链。’”
