A working group will be created in Mexico to investigate the potential impact of genetically modified (GM) corn imports on the country's tortillas, a national staple, due to a trade dispute with the United States. The dispute arose after Mexico restricted imports of GM corn, leading the US to argue that it could contaminate native corn varieties and pose health risks. The US contests these claims, citing a need for a science-based approach to domestic regulations under the US trade agreement. Mexico's health authority, Cofepris, and scientific council, Conacyt, will oversee the working group in assessing the risks associated with transgenic corn consumption. This announcement follows Mexico's decision to ban the consumption of GM corn, a move that could affect the future of animal feed imports and the majority of corn imported from the US, amounting to about 17 million tons annually.
