Genetically Modified Organisms (GMOs) are experimental plants or animals that have been genetically engineered in a laboratory with DNA from other plants, animals, bacteria and viruses. GMOs are designed for two main reasons, either to make plants resistant to the seed producer's pesticide or to modify plants in such a way that they produce built in pesticides.

80% of all packaged foods in the US contain genetically engineered (GE) crops, often present in processed foods such as oils, sweeteners, soy proteins, high fructose corn syrup amino acids, aspartame, vitamin C, natural and artificial flavorings, maltodextrin and more. In the US, 93% of soy, 93% of cotton, 86% of corn, and 90% of canola are genetically modified. The labeling of GMOs is required in forty countries around the world, many of them banning them outright. However, the US and Canada do not require any labeling of such.
