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.}}</ref> <ref>{{Chú thích web|url=http://www.fao.org/docrep/006/Y5160E/y5160e10.htm#P3_1651The|tựa đề=State of Food and Agriculture 2003–2004.

These conclusions represent the consensus of the scientific evidence surveyed by the ICSU (2003) and they are consistent with the views of the World Health Organization (WHO, 2002). These foods have been assessed for increased risks to human health by several national regulatory authorities (inter alia, Argentina, Brazil, Canada, China, the United Kingdom and the United States) using their national food safety procedures (ICSU). To date no verifiable untoward toxic or nutritionally deleterious effects resulting from the consumption of foods derived from genetically modified crops have been discovered anywhere in the world (GM Science Review Panel). Many millions of people have consumed foods derived from GM plants – mainly maize, soybean and oilseed rape – without any observed adverse effects (ICSU).}}</ref> <ref>{{Chú thích tạp chí|vauthors=Ronald P|date=May 2011|title=Plant genetics, sustainable agriculture and global food security|journal=Genetics|volume=188|issue=1|pages=11–20|doi=10.1534/genetics.111.128553|pmc=3120150|pmid=21546547|quote="There is broad scientific consensus that genetically engineered crops currently on the market are safe to eat.

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).

However, it is important to remark that for the first time, a certain equilibrium in the number of research groups suggesting, on the basis of their studies, that a number of varieties of GM products (mainly maize and soybeans) are as safe and nutritious as the respective conventional non-GM plant, and those raising still serious concerns, was observed. Moreover, it is worth mentioning that most of the studies demonstrating that GM foods are as nutritional and safe as those obtained by conventional breeding, have been performed by biotechnology companies or associates, which are also responsible of commercializing these GM plants. Anyhow, this represents a notable advance in comparison with the lack of studies published in recent years in scientific journals by those companies.}} {{Chú thích tạp chí|last=Krimsky|first=Sheldon|date=2015|title=An Illusory Consensus behind GMO Health Assessment|url=http://www.tufts.edu/~skrimsky/PDF/Illusory%20Consensus%20GMOs.PDF|journal=Science, Technology, & Human Values|volume=40|issue=6|pages=883–914|doi=10.1177/0162243915598381|archive-url=https://web.archive.org/web/20160207171524/http://www.tufts.edu/~skrimsky/PDF/Illusory%20Consensus%20GMOs.PDF|archive-date=7 February 2016|access-date=30 October 2016|quote=I began this article with the testimonials from respected scientists that there is literally no scientific controversy over the health effects of GMOs.

The presented articles suggesting possible harm of GMOs received high public attention. However, despite their claims, they actually weaken the evidence for the harm and lack of substantial equivalency of studied GMOs.

However, safety concerns cannot, as yet, be dismissed completely on the basis of information currently available. When seeking to optimise the balance between benefits and risks, it is prudent to err on the side of caution and, above all, learn from accumulating knowledge and experience. Any new technology such as genetic modification must be examined for possible benefits and risks to human health and the environment. As with all novel foods, safety assessments in relation to GM foods must be made on a case-by-case basis. Members of the GM jury project were briefed on various aspects of genetic modification by a diverse group of acknowledged experts in the relevant subjects. The GM jury reached the conclusion that the sale of GM foods currently available should be halted and the moratorium on commercial growth of GM crops should be continued. These conclusions were based on the precautionary principle and lack of evidence of any benefit. The Jury expressed concern over the impact of GM crops on farming, the environment, food safety and other potential health effects. The Royal Society review (2002) concluded that the risks to human health associated with the use of specific viral DNA sequences in GM plants are negligible, and while calling for caution in the introduction of potential allergens into food crops, stressed the absence of evidence that commercially available GM foods cause clinical allergic manifestations. The BMA shares the view that there is no robust evidence to prove that GM foods are unsafe but we endorse the call for further research and surveillance to provide convincing evidence of safety and benefit.}}</ref> Tuy nhiên, các thành viên của công chúng ít có khả năng hơn các nhà khoa học nhận thức thực phẩm biến đổi gen là an toàn. <ref>{{Chú thích web|url=http://www.pewinternet.org/2015/01/29/public-and-scientists-views-on-science-and-society/|tựa đề=Public and Scientists' Views on Science and Society|tác giả=Funk|tên=Cary|tác giả 2=Rainie|tên 2=Lee|ngày=29 January 2015|nhà xuất bản=Pew Research Center|ngày truy cập=24 February 2016|trích dẫn=The largest differences between the public and the AAAS scientists are found in beliefs about the safety of eating genetically modified (GM) foods.
