Mexico submitted an official reply to the United States in the US-Mexico-Canada Agreement (USMCA) trade dispute about importing genetically modified (GM) corn. Mexico argued that the herbicide glyphosate in the corn is unsafe for human consumption. Corn plays a vital role in the Mexican diet, particularly as the primary ingredient for tortilla flour.

In a written submission to a USMCA panel, Mexico, the top buyer of US corn, used science to show how GM corn and Glyphosate harm human health. This has given Mexico the authority to ban GM corn for human consumption.
