Genetically Modified Organisms (GMOs) refer to plants and animals with an altered genetic make-up. GMOs are generally altered or manipulated by a non-natural means in order to incorporate genes from another organism. Usually genetic engineering (GE) is done to achieve a trait not normally held by an organism, such as longer shelf life, disease resistance or different colors or flavors.
The dangers vs. benefits of GMOs are widely debated, but genetic modification is currently allowed in conventional farming. In fact, many organizations and studies estimate that possibly 70% or more of all processed foods sold to consumers now contain genetically modified ingredients.
As it stands right now, any food item that is certified organic CANNOT contain genetically modified ingredients.
The National List prohibits GMOs in organic foods.
