Genetically modified organisms (GMOs) have been on the commercial market for many years, yet their safety remains contentious. Is it safe to eat GMO food? Why has GMO corn triggered a trade dispute between the United States and Mexico?
About 90 percent of the corn planted in the United States is genetically modified, and Mexico is a major buyer, purchasing nearly 30 percent of the total U.S. corn exports. However, in 2020, Mexican President Andrés Manuel López Obrador issued a decree banning the import of GMO corn starting in January 2024.
