Mexico has new rules for genetically modified corn.

And those new rules, published Monday, prohibit the use of GMO corn for human consumption, specifically highlighting the production of flour for tortillas.

However, Mexico’s economy ministry noted the elimination of an early 2024 deadline for phasing out GMO corn for animal feed and industrial food production.

A more sweeping 2020 decree had been a source of tension between the United States and Mexico, with U.S. Secretary of Agriculture Tom Vilsack saying last November that such a policy could have serious trade impacts. Vilsack reportedly said in a statement Tuesday that he was "disappointed" in the latest decree.
