Why does Mexico want to ban GMO corn?

Mexico’s ban on biotech corn has left the U.S. ag industry baffled. Many U.S. ag industry leaders argue that Mexico’s stringent regulations on GMO corn are not based on science. However, experts with Ambrook Research explain that the regulation is not a matter of human health, but rather a way to prevent genetically modified crops from threatening the nation’s cultural food heritage.

In early 2023, the USMCA trade partner introduced a 50% tariff on white corn imports and modified regulations to ensure tortilla makers use only non-genetically modified white corn.

In Mexico, corn is more than just a commodity crop. It is considered a big part of heritage, culture, and tradition. The country is home to more than 50 native corn varieties, and Mexican leaders believe that incredible biodiversity could be threatened if genetically modified crops are introduced.
