A: The quick answer for regulatory studies is 90 days for GMO safety and 26 months for glyphosate (the active ingredient in Roundup agricultural herbicides) safety. The lengths of these studies are assessed and set by independent scientific bodies globally, in order to ensure product developers generate comprehensive data to appropriately determine the long-term safety of new products. This question is similar to others on the site about safety testing and long-term safety. I’ve pulled... Continue Reading
Q: Are antibiotic resistance genes removed from GMOs? If so, how is this achieved? If not, are these marker genes tested for safety?

A: Antibiotic resistance genes are used in some GMOs to identify plants where the added DNA has been successfully incorporated. While this idea could understandably lead to questions -- Antibiotic resistance genes in my food? -- multiple safety reviews conducted by regulatory agencies around the world have confirmed that the presence of an antibiotic resistance gene does not pose any unique safety concerns.One of the first steps associated with GMO development is identifying the plants that...

A: As you and other farmers are well aware, weed control is one of the keys to good yields. GM crops that can tolerate glyphosate, the active ingredient in Roundup agricultural herbicides, provide a simplified approach to weed control and allow farmers to rely on an herbicide with a thoroughly documented record of safe use. Glyphosate is well known for its low toxicity to humans, farm animals and wildlife. From time to time, there are reports of glyphosate being detected in samples collected... Continue Reading

A: If you were to look for a common theme among most of the questions and responses on GMO Answers, your question would be it! GMOs have been in our food supply for almost 20 years, and GM ingredients are found in 70 to 80 percent of the foods on your grocery store shelves. If GMOs were not safe, we would have a big problem. Fortunately, science shows us that there is no evidence of harm from GMOs. GM crops are repeatedly and extensively tested for consumer and environmental safety, and... Continue Reading

A: Thank you for taking the time to visit GMO Answers, and for your question regarding the approved GM products on the market. As you may know, in the late 20th century, advances in technology enabled scientists to expand the genetic diversity of crops. For decades, dedicated researchers from universities, government and private companies have worked to create safe technologies, including plant biotechnology, that have helped farmers around the globe increase the yield of crops while requiring...
