Expert Panel to Mexico GM Corn Tribunal: Respect the Science

There is a mountain of evidence that both GM corn and its accompanying herbicides, including glyphosate, may cause serious health problems.

The three-member trade panel hearing the U.S. complaint over Mexico’s restrictions on the use of genetically modified corn in tortillas will no doubt need some scientific advice to evaluate the technical evidence presented by the Mexican government on the risks associated with GM corn and their accompanying herbicide residues. They got some on April 23 from a panel of experts assembled by the Institute for Agriculture and Trade Policy (IATP) in the first of three webinars on the GM corn dispute.

Their message could not have been clearer. The Mexican government is right to doubt U.S. assurances that GM corn is safe to eat given the lax regulatory processes for GM crops in the U.S. There is a mountain of evidence that both GM corn and its accompanying herbicides, including glyphosate, may cause serious health problems. And those risks are magnified for Mexicans, who eat more than ten times the corn we eat in the U.S. and do so in minimally processed form, not processed foods.

“Has the U.S. government provided sufficient evidence to the Mexican government to assure the safety of GM corn, which is routinely sprayed with multiple herbicides known to be associated with reproductive problems, metabolic syndrome, and cancer?” asked pesticide expert Dr. Charles Benbrook in his remarks during the webinar. “No, because the studies have never been done.”
