Abstract: Genetically Modified (GM) plants are rapidly entering the food system in the world. These modifications, which are intended to enhance plant productivity and product quality, make use of genetic engineering. This technology offers enormous potential for creation of plants optimized for food and fiber production in support of human needs. However, there is increasing concern about the use of genetic engineering for plant improvement, particularly about possible deleterious effects on human health and about the impacts of the widespread deployment of genetically modified plants in the environment. Different policies are governed this issue around the world. While several European countries have developed positions that do not welcome genetically modified food products in their fields or markets, one may find more flexibility in North America. However, restrictive planting or food labeling requirements are being introduced or considered in both Europe, North America and elsewhere. Governments and regulatory agencies face significant challenges in providing consumers with unbiased information and maintaining consumer confidence in the food supply. The impact of different aspects of GM on our food system will be discussed in detail.
