国外的很多实验证明转基因有一定的问题，你怎么能说没有一列呢？如果能看的懂英语看看下面的一段文章，或者用英语去Google上去搜索转基因食品研究，看看争议有多大！！！
Bt Toxin Triggers Immune Response
Bt toxin is consistently associated with immune and allergic-type responses. Although the unpredicted consequences of the GM transformation process might also contribute to allergic reactions from Bt crops, evidence suggests that the Bt toxin itself is a major factor. The Bt proteins found in most currently registered Bt-corn varieties would not pass the allergy test protocol described in the 2001 FAO/WHO report,16 because they have amino acid sections identical with known allergens17 and are too stable in simulated digestive solutions.18,19
Furthermore, immune responses are triggered by both the natural Bt toxin in spray form and Bt crops. The concentration of Bt toxin in crops, however, can be thousands of times higher than in sprays;20 and changes in its protein structure make the crop version more likely to provoke reactions in humans.21,22
Additional evidence:
• When populations were exposed to Bt spray, hundreds complained of allergic reactions; exposed farm workers also exhibited antibody responses.23–27
• Indian farm workers exposed to Bt cotton developed moderate or severe allergic reactions.28
• Bt toxin fed to mice induced a significant immune response and an increased reactivity to other substances.29-31
• Male rats fed MON 863 Bt corn had a significant increase in three types of blood cells related to the immune system: basophils, lymphocytes, and total white cell counts.32
• Thousands of consumers complained to food manufacturers about possible reactions to StarLink corn,33 and an expert panel determined that its Bt protein had a “medium likelihood” of being a human allergen.34
