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
Q: How credible is Jack Heinemann or Bill Freese are? They have been mentioned in some blogs about their expertise in anti gmo sites. And Isoxaflutole, it's toxicity studies?

A: Generally speaking, credibility, as it relates to scientific data, can be established via independent replication of study results and ultimately leads to acceptance of the data by other scientific experts. In consideration of newly generated data or the absence of study replication, credibility can be obtained by evaluating and characterizing the data against sets of criteria presented in several excellent publications (Klimisch et al., 1997; Conrad and Becker, 2011; Henry and Conrad, 2008)....
