As the US Pressures Mexico to Import GM Corn, Can It Preserve Its Traditional Varieties?

As the US Pressures Mexico to Import GM Corn, Can It Preserve Its Traditional Varieties?

Just two years ago, they celebrated a major victory, when President Andrés Manuel López Obrador issued the first executive order that directed the government to “revoke and refrain from granting authorizations” for the use of genetically modified (GM) corn in Mexican diets and for “release into the environment” by January 2024. While growing GM corn in Mexico has not been allowed for 25 years, millions of tons of the corn enter the country each year via imports. The order also called for a complete phaseout of the controversial herbicide glyphosate by that date.

Now, however, in the face of U.S. pressure, Mexico is weakening the ban, which was in part intended to prevent genetically modified seed from contaminating native varieties.

Because the executive order was short on specifics, it was unclear from the start what it would mean for the 17 million tons of mostly GM corn exported to Mexico from the U.S. every year—used primarily for livestock feed. And since last fall, U.S. officials, including Secretary of Agriculture Tom Vilsack, have been meeting with Mexican officials to advocate for its reversal.

Vilsack and others said the recent order violated the free trade agreement between the U.S. and Mexico, a fact that some analyses of the agreement’s language dispute. As officials negotiated, preliminary reports suggested López Obrador’s government would stick to including corn used for livestock feed but delay the start date of the ban to 2025 to alleviate U.S. concerns.

Then, at the end of January, the U.S. agriculture trade chief demanded Mexican officials provide scientific evidence to support the bans on both GM corn and glyphosate by February 14. And finally, last week, the Mexican government issued an order that came with new clarifications. Officials said the ban on GM corn would still apply to corn used in flour, dough, or tortillas but not to livestock feed or industrial uses.

“It leaves the door open to GM corn coming from the U.S., and that, from our perspective, still poses a risk,” said Gustavo Ampugnani, the executive director of Greenpeace Mexico, in an interview with Civil Eats.
