The Mexican government has officially banned the domestic cultivation of genetically modified (GM) corn, a move that was previously effectively banned since 1998 and 2013 due to court rulings. The ban, introduced on 17 March, defines GM corn as produced with techniques that overcome natural reproduction barriers and requires any use of such corn to be evaluated for potential risks to biodiversity, health, and biocultural heritage. The broad application of the term "use" in the amendment has led to questions about whether the restrictions also apply to GM corn grain imported for food, feed, or processing uses. The government's aim is to preserve native corn varieties, protect biodiversity, and ensure food sovereignty.
