"We are grateful that Secretary Vilsack is taking seriously our concerns and recommendations regarding the department's oversight of GE crop field trials," says Kristina Hubbard, director of advocacy and communications for Organic Seed Alliance.
"Protecting the genetic integrity of seed and crops must begin at the field trial stage. We hope the department moves forward in fully implementing necessary improvements to protect American farmers and the markets they serve. But these improvements will only be as strong as the department's oversight and enforcement."
"This is an issue that affects all farmers, regardless of convention and their markets," Hubbard says.
