转基因食品争议

有关转基因食物的争议
（重定向自转基因阴谋论）

转基因食品争议（英语：Genetically modified food controversies）是指关于食用转基因作物及其副产品、在食品生产中利用基因工程技术而非植物配种等方面的争议。这场争议与消费者、生物技术公司、政府管理者、非政府组织和科学家都密切相关。关于基因改造食品的争论核心包括：转基因食品的上市标注、政府管理者的责任、相关科学研究的目的、转基因作物对环境和健康的影响、对害虫之抗药性（英语：Pesticide resistance）的影响、对农业生产者的影响和转基因作物对满足全球粮食需求的作用。

公众对转基因食品的具体担忧包括对于转基因食品与非转基因食品在供应上的影响[1]，转基因食品对环境造成的影响[2][3]，监督者是否会渎职[4][5]。食品安全中心（英语：Center for Food Safety）、有机产品消费者协会（英语：Organic Consumers Association）、相关科学家联合会（英语：Union of Concerned Scientists）及绿色和平等相关利益团体认为转基因相关的风险并没有被正确认识和应对，同时质疑监管机构的客观性。

目前的科学共识是此类转基因作物及其副产品的健康安全风险并不高于传统食品[6][7]，也就是说转基因作物的安全性是可以保证的[8][9]，不过即便如此目前对转基因的安全评估依然十分严格[10]。对转基因食品的安全评估始于鉴定该食品是否与同类非转基因食品实质性等同（英语：Substantial equivalence），即确认转基因食品是否与已经被确认无害的传统食品是否本质相同，且目前还没有报告称转基因食品在人身上造成疾病[11][12][13]，但公众还是担心转基因食品有害健康[14][15]。虽然针对转基因生物产品的标注在许多国家是强制性的，但美国和加拿大并不执行类似政策，在市场上转基因食品和传统食品是没有差别的。

公众认知

编辑

尽管重视食品卫生的思想自古已有之，但在美国，直到厄普顿·辛克莱的小说《屠场》出版以及纯净食品药物法案（英语：Pure Food and Drug Act）出世后，这一问题才正式被公众所广泛讨论[16]。这进一步导致了人们对食品纯度、食品“天然度”的长期关注，这种关注随后演变到了对防腐剂、香料、甜味剂、农药残留物的担忧，有机食品的崛起以及最终对转基因食品的担忧。许多消费者认为转基因食品是“非天然的”并对转基因食品充满负面联想和恐惧（这被认为是一种逆向的晕轮效应）[17][18]。

公众的看法包括但不限于将基因工程视为干预自然进化的生物过程，以及认为科学在潜在危害的评估时有局限[19]。不过，一种反对的看法认为基因工程就是传统选择性育种的演变，且现有证据证明转基因食品在营养价值和健康方面与传统食品相同（即实质性等同）[20][21]。

一系列的研究指出，人们担忧进食转基因食品对身体有害[22][23][24]；担忧生物技术的风险十分高；担忧自己了解的信息不足，不敢冒着风险进食[25][26]。

There is broad scientific consensus that genetically engineered crops currently on the market are safe to eat. After 14 years of cultivation and a cumulative total of 2 billion acres planted, no adverse health or environmental effects have resulted from commercialization of genetically engineered crops (Board on Agriculture and Natural Resources, Committee on Environmental Impacts Associated with Commercialization of Transgenic Plants, National Research Council and Division on Earth and Life Studies 2002). Both the U.S. National Research Council and the Joint Research Centre (the European Union's scientific and technical research laboratory and an integral part of the European Commission) have concluded that there is a comprehensive body of knowledge that adequately addresses the food safety issue of genetically engineered crops (Committee on Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health and National Research Council 2004; European Commission Joint Research Centre 2008). These and other recent reports conclude that the processes of genetic engineering and conventional breeding are no different in terms of unintended consequences to human health and the environment (European Commission Directorate-General for Research and Innovation 2010).

    关于生物多样性和转基因食品/饲料消费的文献常引起激烈争论，这涉及到了实验设计的适用性、统计方法的选择以及数据的公众可获取性。然而，在这场争论中即便是科学界内常态的、自然的同行评审也常常被媒体歪曲并常用于政治化和扭曲转基因相关技术。（We have reviewed the scientific literature on GE crop safety for the last 10 years that catches the scientific consensus matured since GE plants became widely cultivated worldwide, and we can conclude that the scientific research conducted so far has not detected any significant hazard directly connected with the use of GM crops.

    The literature about Biodiversity and the GE food/feed consumption has sometimes resulted in animated debate regarding the suitability of the experimental designs, the choice of the statistical methods or the public accessibility of data. Such debate, even if positive and part of the natural process of review by the scientific community, has frequently been distorted by the media and often used politically and inappropriately in anti-GE crops campaigns.）

G.M.O.s, in contrast, suffer from a reverse halo effect, whereby one negative-seeming attribute (unnaturalness, in this case) skews over-all perception. In a 2005 study conducted at Maastricht University, in the Netherlands, researchers found that the more unnatural a genetically modified product seemed, the less likely it would be to gain acceptance. A hundred and forty-four University of Maastricht undergraduates were asked to visualize seven products, including butter, tomatoes, and fish fingers, and rate them on naturalness, health, and necessity.
