1. Introduction

Nowadays use of technology of genetic modification in global agriculture and supply of food and feed is quite complicated due to the active anti-GM technology policy of Green Peace, Friend of the Earth and other groups of interest. As a consequence of this activity large quantity of GMO-based ingredients manufactured for human consumption has been eliminated by EU. This anti-GMO assumption recently is directed to the use of genetically modified ingredients in livestock production. Through the introduction of genetically modified oilseeds and cereals in animal feed, European Commission in 2001 proposed legislative changes to restart the process of GMO based technologies. If case of success of this policy, it will bring important economic consequences to the EC economy. Thus, the clarification of the questions related to scientific and safety issues associated with GMMs are of crucial importance.
