Abstract: From the origins the man has looked and selected vegetables with nutritive value for larger productivity. The knowledge of DNA structure allowed genetic engineering to develop and supplying tools for the accomplishment of specific alterations in the genome considerably. The products of these alterations are denominated transgenic or organisms genetically modified (OGM) and they present high application potential in several areas of the human activity as: agriculture, medicine, health, production and processing of foods, biochemical production and control of diseases. Nowadays, transgenic plants, originating from technology of the DNA recombinant, brought new varieties cultivated already in more than 100 million hectares in 23 countries, including Brazil, where 8 varieties were already approved for the National Technical Commission of Biosafety (CTNBio). That method of genetic improvement facilitated the introduction of desirable characteristics in plants, such as, resistance to biotic and non-biotic stress and optimization of the composition of some essential nutrients to the animal and human health. While these progresses of the biotechnology open new perspectives for the solution of problems in areas as the agriculture, the transgenic liberation for use in the nature brings concerns as for possible problems of ecological nature and for the human and animal health. These concerns brought the creation of government agencies to control the use of this technology and to regulate the safety of transgenic foods and yours derived. Until the moment, the scientific studies show that the transgenic liberated commercially are so safe or more to the environment and the animal and human health that the conventional ones. © 2009 Sociedade Brasileira de Zootecnia.
