Mexico Set to Ban Imports of Genetically Modified U.S. Corn

Dec 20, 2023

With just two weeks to go until the start of the new year, it appears Mexico will make true on its promise to ban the import of U.S. genetically modified corn beginning Jan. 1, 2024.

Chris Cherry, president of the Indiana Corn Growers Association, said it is likely the ban will be challenged by a USMCA dispute panel.

“While they're in disputes, maybe that timeline will get pushed back a little bit,” he said. “So, maybe it won't be a hard, fast January like they intended, since the USTR (United States Trade Representative) is kind of involved.”

In 2020, Mexico published a presidential decree phasing out the import of GM corn for human consumption by 2024. Then in 2023, the original decree was modified to outright ban it for human consumption and even elaborated that substitutes for animal feed would be explored in order to phase out the crop.

They are now only interested in white corn specifically, a crop which makes up between four and six percent of U.S. corn exports. Mexico will import yellow corn primarily from Brazil and Argentina to make up for the loss in U.S. imports.

Cherry, along with Agriculture Secretary Tom Vilsack, said that there is no scientifically based reason for Mexico to ban genetically modified corn.

“The EU has approved GM corn,” Cherry said. “And they historically have been our toughest, between the EU and China, getting approval in those countries has been the toughest. They understand the science behind it, and they've accepted it. We feel that it's not based on sound science.”

In 2022, the U.S. produced 13.7 billion bushels of corn, with Mexico bringing in three billion bushels of that total, making it the number one importer of the good.

“Mexico's overall grain exports are down around 12-13% in 2023, so that's a huge number,” he said. “When you're talking three billion bushels, and you take 12% off that, that's pretty big number. This will continue to get worse over time if they're banning this outright.”

Cherry said the reason U.S. corn growers rely heavily on GM corn is due to the ease and affordability of growing the crop.

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
