FOOD SOVEREIGNTY
Mexico’s Fight To Keep GMO Corn off Its Plates Is Far From Over and It’s Heating Up
Organic Consumers Association:Even after a United States–Mexico–Canada Agreement (USMCA) dispute panel ruled against Mexico’s ban on genetically modified white corn imports, claiming the policy “wasn’t science-based” and hurt U.S. exports, Mexico isn’t backing down.
The ban on planting GMO corn in Mexico still stands, and lawmakers are now exploring new legislation that would permanently prohibit GMO corn cultivation nationwide.
At the heart of this resistance is the “Demanda Colectiva Maíz” (Maíz Collective Lawsuit), a powerhouse alliance demanding the Mexican government defend native corn, food sovereignty, and public health. The Collective argues the U.S. has yet to prove GMO corn is safe for the Mexican people — and says Mexico has every right to protect its agricultural heritage.
Mexico’s battle to keep GMO corn out of its food supply is deeply rooted in preserving native corn varieties to secure the livelihoods of small-scale farmers who produce over 80% of Mexico’s maize, and its crucial role in the nation’s health and heritage. Native corn has been cultivated for thousands of years, resulting in 64 “landraces” and over 22,000 varieties adapted to different environments. This biodiversity is essential for Mexico’s food sovereignty and the health of its people.
Mercedes López Martínez, a leading voice in the Collective, has sharply criticized Mexico’s Ministry of Economy for putting corporate interests ahead of national sovereignty and emphasizes that native corn isn’t just a crop, it’s culture, resilience, and the living heart of Mexico.
The Collective, made up of 22 civil society organizations and 52 individual advocates, is standing firm to protect that legacy. OCA proudly supports this effort through our sister organization, Vía Orgánica, where Mercedes helps lead the charge.
In a significant win, a federal court has ordered Mexico’s Ministry of Economy to formally respond to the Collective’s petition to activate USMCA mechanisms against the U.S. over agricultural biotechnology.
