GMO Contamination


Once released into our environment, genetically modified (also called genetically modified or GM) organisms are difficult or impossible to control or recall. Every release of a GM organism is an experiment – ​​some more controlled and controllable than others.

GMO Contamination

GM contamination is the unwanted escape and spread of GMOs or genetic material from GMOs to non-GMO plants, animals and foods. This dispersal can occur in a variety of ways, including pollen dispersal and seed escape, and mixing of food and feed. 

GM contamination is a living self-replicating contamination. Such pollution can have adverse environmental, social and economic impacts. Until now, farmers have been the first to pay the price of contamination with GMOs.

Pollution Ways

Contamination of non-GM crops with genetically modified traits can occur in a variety of ways and at a number of links in the food chain. It can be the result of natural processes or human activity.

  • Cross pollination: Pollen from GM plants can spread to non-GM plants carried by wind, insects or other animals. The probability and distance from which this contamination occurs differs from one species to another and depends on how the plant pollinates, how far its pollinators can travel, and other aspects of its biology. GM volunteers and wild plants can also sustain cross pollination.
  • Seed escape and mixing of food and feed: GM seed can escape and mix with non-GM seeds during seed production or through the use of farm equipment, during transportation and storage, and even in clothing and shoes. Seeds spilled during transport can cause wild or voluntary GM plants to grow along transport routes. Domestic or wild animals can also spread GM seed. GM and non-GM products may also be mixed during storage and milling, and GM and non-GM food and feed may be mixed during processing.
