【正文】 nd WHO developed a sufficient number of rules and regulations to reduce the risk of what39。 key nutrients。 potential for gene transfer from geically modified foods to human/animal gut flora。 Figure 1). The concept of substantial equivalence is part of a safety evaluation framework based on the idea that existing foods can serve as a basis for paring the properties of a geically modified food with the appropriate counterpart. The existing food supply is considered to be safe, as experienced by a long history of use, although it is recognized that foods may contain many antinutrients and toxicants which, at certain levels of consumption, may induce deleterious effects in humans and animals. Application of the concept is not a safety assessment per se, but helps to identify similarities and potential differences between the existing food and the new product, which is then subject to further toxicological investigation. Three scenarios are envisioned in which the geically modified plant or food would be (i) substantially equivalent。 Geically modified food safety issues Abstract As we all know,modern biotechnology has brought human numerous benefits:Through the application of biotechnology, a broad and significant increase of food production can be happily seen at global agricultural production. But when we enjoy the enormous benefits of the GM food,a new but alarming problem also came that if these food is safe enough for people?if something seriously happened,what can we do?Maybe you can find some answer in this thesis.
