The Food Democracy Website reports that “On January 17, internationally recognized plant pathologist Dr. Don Huber, wrote a letter to USDA Secretary Tom Vilsack warning of the discovery of a new pathogen and a possible link between Roundup Ready® (GMO) corn and soybeans and severe reproductive problems in livestock as well as widespread crop failure."
For more information, and to watch an interview with Dr Huber, then see the Food Democracy Website.
And for a commentary on the issue, specifically with reference to the herbicide Glyphosate see Dr Mercola's website.
