GMO基改農產品被證實會嚴重影響食用者健康


GMO基改食物或農產品到底是否安全，有沒有任何副作用呢？可能沒有人可以完整的回答，但隨著更多研究的進行，我們確實發現有些GMO產品對食用者是可能有害的。玉米跟黃豆是當前最大宗的GMO產品，在我們日常飲食的供應鍊當中，他們如影隨形，雖然我們可能看不到他們最原始的風貌，認不出到底存不存在，但很可能無意間都會受到他們的影響。

你對於GMO基改認識多少？姑且不論科學或技術層面的知識，在市場上，看到有些廠商煞費苦心的標明他們沒有使用GMO基改原料，也許就能夠嗅之一二許多人對此是有顧慮的，而這些顧慮到底是多餘的？還是事證確鑿的？

最近看到一篇由澳洲有機協會(Organic Federation of Australia)所發出的電子報文章，名為”基因改造造成顯著健康問題” (GM Causes Significant Health Problems)。平常我們多少都會聽到對於GMO基改農產品的疑慮，有些國家更是完全明文禁止，如今，有相關的科學報告，證實某些GMO農產品對於食用者的健康是有影響的。
這個報告轉載如下，主要在說明在近期19篇關於動物試驗的研究報告當中，雄性動物的腎臟有43.5%受到影響，而雌性動物的肝臟有30.8%受到影響。學者更表示：「讓5億歐洲消費者或數十億的全球消費者與能夠產生農藥的基改食物或飼料接觸是不能接受的事」，這些GMO基改作物的主要功能就是自體產生農藥的成份以便成夠達到防治蟲害的效果，但目前的法規下，這些GMO基改農產品並不需要經過一般農藥所需要經歷的長期安全性試驗，因此學者呼籲在法規上做調整，以確保這類會產生農藥成份的GMO基改農產品需要經過更慎重的把關措施，以確保實用者的安全。

GM Causes Significant Health Problems

A peer reviewed scientific paper published in Environmental Sciences Europe on March 1, 2011 showed that GM corn and soybeans caused significant kidney and liver problems in rats and mice. The scientists have stated: ‘… that it is unacceptable to submit 500 million Europeans and several billions of consumers worldwide to the new pesticide GM-derived foods or feed…’

Professor Gilles-Eric Séralini and colleagues reviewed data from 19 animal feeding studies. They found that the kidneys of males had 43.5% of all the pathological changes and the livers of females had 30.8% of the changes.

The scientists stated that ‘several convergent data appear to indicate liver and kidney problems as end points of GMO diet effects.’

The authors also found problems in other measured parameters such as blood, urine, organ weights and body weights. Microscopic analyses (histopathology) of the organs showed differences between the GM and Non GM fed animals. The scientists stated that ‘Other organs may be affected too, such as the heart and spleen, or blood cells.’

The GM corn and soybean used in the trials constitute 83% of the commercialised varieties and are consumed by hundreds of millions of people. The scientists expressed strong concerns about the current inadequacies of the feeding trials used to evaluate the safety of GMOs.

This is particularly the case of pesticidal GMOs. Every cell of these plants produce a pesticide, however they do not have to undergo the same testing rigour that is applied to pesticides before they are approved.

The scientists stated: ‘We can conclude, from the regulatory tests performed today, that it is unacceptable to submit 500 million Europeans and several billions of consumers worldwide to the new pesticide GM-derived foods or feed, this being done without more controls (if any) than the only 3-month-long toxicological tests and using only one mammalian species, especially since there is growing evidence of concern (Tables 1 and 2). This is why we propose to improve the protocol of the 90-day studies to 2-year studies with mature rats, using the Toxotest approach, which should be rendered obligatory, and including sexual hormones assessment too. The reproductive, developmental, and transgenerational studies should also be performed. The new SSC statistical method of analysis is proposed in addition. This should not be optional if the plant is designed to contain a pesticide (as it is the case for more than 99% of cultivated commercialized GMOs), whilst for others, depending on the inserted trait, a case-by-case approach in the method to study toxicity will be necessary.’
