5. Canola
As with most crops on our list of examples of genetically modified foods with full explanations, the first type of genetically modified canola was Monsanto’s Roundup Ready canola. It was resistant to glyphosate, which is the main active ingredient in many modern herbicides, including Roundup. This has caused an issue because canola seeds can lay dormant up to 10 years in the ground and the plant has appeared as a weed in fields planted with other cultures. Since it is herbicide resistant, it has to be removed manually, hugely increasing cost for farmers.
