Genetically modified foods or GM foods, also genetically engineered foods, are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering techniques allow for the introduction of new traits as well as greater control over traits than previous methods such as selective breeding and mutation breeding.
Fruits and vegetables that are grown in the usual way (with the injection of chemicals) are labeled with a code consisting of four digits. Organically grown fruits and vegetables price tag with a code consisting of five digits, starting with 9.
Genetically modified (GM) fruit and vegetables have a price tag with a code consisting of five digits starting with the number 8 of these tips are quite important , due to the fact that at this time, more than 80 percent of processed foods in the United States has been genetically modified.
Commercial sale of genetically modified foods began in 1994, when Calgene first marketed its unsuccessful Flavr Savr delayed-ripening tomato.Most food modifications have primarily focused on cash crops in high demand by farmers such as soybean, corn, canola, and cotton seed oil.(wikipedia)
In many European countries, the production and sale of GMO products is prohibited. These countries are Austria, France, Germany, Greece, Hungary and Luxemburg.(theworld-aroundus.com)
Genetically modified crops have been engineered for resistance to pathogens and herbicides and for better nutrient profiles. GM livestock have been developed, although as of November 2013 none were on the market.(wikipedia)
