A: Many claims have been made on the Internet that use of glyphosate-resistant (GR) crops and glyphosate can change the composition of soil because glyphosate is a strong chelator- a compound that can bind with metal ions- that will bind to micronutrients in soil. It is also claimed that this will increase the potential for disease to affect plants, or even cause new pathogenic bacteria to be present in the soil that can affect plant, animal and human health. These have all been used as reasons... Continue Reading
Q: The USDA recently approved soybean with stacked glyphosate/isoxaflutole tolerance. A 1998 EPA report designated isoxaflutole as a "probable carcinogen." What is the environmental/toxicological impact of this USDA decision?

A: In approving genetically modified crops, such as soybeans, with dual herbicide tolerance, USDA evaluates the safety of the crop, while EPA assesses the safety of the pesticide used on the crop, which includes consideration of the potential risk of an adverse health effect, such as cancer. Based on exposure estimates provided by EPA (2011), the likelihood that humans are exposed to carcinogenic levels of isoxaflutole (IFT) is extremely low. First and foremost, it should be emphasized that the... Continue Reading

A: This is an important question and has been discussed several times on GMO Answers. You might be interested in these graphics briefly outlining the history of crop modification. According to Dr. Bruce Chassy, professor emeritus of food safety and nutritional sciences at the University of Illinois at Champaign-Urbana, “GM crops have been planted on more than 2 billion hectares by more than 17 million farmers over 17 years in about 30 countries, with no adverse ecological impacts...

A: This is a great question. Cathleen Enright, executive director for the Council for Biotechnology Information, answered a similar question. Here is an excerpt:“There are a number of reasons consumers may prefer to purchase non-GMO. Many of those reasons have been expressed on this website, but concern about food safety or health shouldn’t be one of them. This is why we support voluntary marketing labels for those companies who want to distinguish their non-GM food from their GM food, and so... Continue Reading
