Monsanto, the world's largest biotech corporation, is via key political appointees also in control of the United States Department of Agriculture. Consider this quote from the below link.  "The USDA has, in fact, never denied a single application from Monsanto for new genetically engineered crops. Not one. Not ever."  Indeed, "Monsanto's board members have worked for the EPA, advised the USDA, and served on President Obama's Advisory Committee for Trade Policy and Negotiations."  This despite its products being banned by other nations.  Why the thought of banning their products?  Another quote:  "A recent study links Roundup to autism, Parkinson's, and Alzheimer's."  There is more.
