ABSTRACT
The current paper reviews on genetically modified crops and its impact on environment. The need forscreening and testing increases as more changes are made, and "second-generation" GMs will require more testing. Todate no adverse health effects caused by products approved for sale have been documented, although two productsfailed initial safety testing and were discontinued, due to allergic reactions. Most feeding trials have observed no toxiceffects and saw that GM foods were equivalent in nutrition to unmodified foods, although a few reports attributephysiological changes to GM food. However, some scientists and advocacy groups such as Greenpeace and WorldWildlife Fund consider that the available data do not prove that GM food does not pose risks to health, and call foradditional and more rigorous testing before marketing genetically engineered food [3]. Therefore, before a crop isdeclared environment friendly safety assessment is recommended. If any safety concern is identified, the risk associatedwith it should be characterized to determine effect on human health. Subsequent assessments should consider factorssuch as toxicity, allergenicitY, antinutrients and metabolites, the stability of the inserted gene and nutritionalmodification associated with genetic modification. If the entire assessment of these factors concludes that the GM foodin question is as safe as its conventional counterpart, the food is then considered safe to eat.
