According to the World Health Organization, the so-called genetically modified organisms are actually "genetically modified organisms", which change genetic material (DNA) by natural means without mating and/or natural recombination. The purpose may be for higher yield, faster maturity, better appearance, better drought resistance, better insect resistance, easier storage, lower price and so on. The answer given by the World Health Organization (WHO) is that different genetically modified foods have different genes added in different ways, which means that the safety of each genetically modified food should be evaluated according to specific conditions, and this issue cannot be generalized.

According to the introduction of China Agricultural Biotechnology Society: "Transgenic products can be divided into two categories: one is transgenic insect-resistant cotton and transgenic virus-resistant papaya planted and produced in China; The other category is genetically modified soybeans, genetically modified corn, genetically modified rapeseed, genetically modified beets and genetically modified cotton imported from abroad, which are mainly used as processing raw materials. "

The National Academy of Sciences, the National Academy of Engineering and the National Medical College convened more than 50 experts to form an expert committee. After collecting, sorting out and identifying thousands of transgenic research reports in recent two years, 20 16 jointly released a 606-page research report. The conclusion is as follows: "There is no conclusive evidence that there are differences in health risks between genetically modified crops planted commercially and those planted by traditional methods. Any disease has nothing to do with eating genetically modified food. Compared with ordinary food, genetically modified food does not increase human health risks. "

Academician Xu Zhihong of China pointed out that the safety of genetically modified organisms has very strict management and approval standards, including safety evaluation, variety approval, seed production license, seed business license, production and processing license and so on. The evaluation of genetically modified crops is the most rigorous evaluation of crop varieties in history, which requires not only food safety evaluation but also environmental safety evaluation. Academician Xu emphasized that genetically modified crops that have been scientifically evaluated and approved according to law are safe and the risks can be prevented.
