Is gm food safe?

Description: Genetic modification (GM) of organisms is an outstanding scientific achievement of biotechnology and molecular biology in recent years. Genetic modification is generation of organisms by combining genes of different species using recombinant DNA technology. Genetic modification of plants can be carried out by different methods of molecular biology which have been widely discussed in the literature. In each case, it results in the presence of recombinant DNA, which produces new proteins. Unexpected and unintended effects can be seen with all methods of breeding. An undesired effect does not imply a health hazard, although clearly a plant expressing novel and unexpected characteristics warrant closer inspection prior to commercial release. Between 1997 and 2010, the total surface area of land cultivated with GMOs had increased by a factor of 87 from 17,000 km2 (4.2 million acres) to 1,480,000 km2 (365 million acres). 10% of the world's crop lands were planted with GM crops in 2010. In 2010, countries that grew the most transgenic crops were the United States (45%), Brazil (17%), Argentina (15%), India (6%), Canada (6%), and China (2%). The increasing trend in terms of growth of GM crops in North America requires closer examination for ensuring its safety. The first step in assessing the potential of an adverse outcome is to identify suspected compositional changes and then assess their potential for adverse health effects. The current safety assessment lies in comparing GM food with its conventional counterpart to identify uniquely different components. Currently, we can use high-performance separation methods to analyze GM food or other various nucleotide-based amplification methods or protein-based methods. However, there is still a long way for us to go to ensure the safety of GM food by more accurate methods.
