A genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques.Organisms that have been genetically modified include micro-organisms such as bacteria and yeast, insects, plants, fish, and mammals.GMOs are the source of genetically modified foods, and are also widely used in scientific research and to produce goods other than food. genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques.
There is general scientific agreement that food on the market from genetically modified crops is not inherently riskier to human health than conventional food. No reports of ill effects have been documented in the human population from GM food.ost food modifications have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil. These have been engineered for resistance to pathogens and herbicides and for better nutrient profiles.
