Impact of GMO corn ban on Mexican consumers

Impact of GMO corn ban on Mexican consumers


By Jamie Martin

A recent study by the University of Arkansas Division of Agriculture highlights the potential impact of a fully implemented ban on genetically modified (GMO) corn in Mexico.

The ban could disproportionately affect lower-income consumers in Mexico and negatively impact American corn farmers, as Mexico is a major importer of U.S. corn.

Corn plays a crucial role in Mexican diets, with tortillas providing 13–20% of daily calories for many. Eggs and poultry are also significant protein sources, relying heavily on corn feed.

Surveying over 1,300 Mexicans, researchers found that “more than half of the people we surveyed in Mexico were not even aware of the ban, and of those who did know about it and supported it, many of them changed their opinion when they saw how much prices could go up and how many jobs could be lost,” stated Brandon McFadden, a professor at the University of Arkansas and study co-author.

The 2020 decree, introduced by President Andrés Manuel López Obrador, aimed to phase out GMO corn and the herbicide glyphosate by 2024.

While modified for animal feed in 2023, the ban still impacts imports of yellow maize used for livestock. This restriction could lead to increased food prices, reduced access to affordable proteins, and significant job losses.

The survey indicated that consumers are willing to pay more for non-GMO foods, with low-income respondents willing to pay a premium of up to 46% on certain products. Many supporters cited health and environmental concerns as their main reasons.

Lower-income consumers, who are more dependent on tortillas and eggs, may face increased financial stress if the ban raises food prices.

Research from similar bans in Zimbabwe and Kenya shows that restrictions can lead to severe food insecurity, demonstrating the need for a careful balance between regulation and food security.
