# GRAIN | Mexico: The dangers of industrial corn and its processed edible products

> A GRAIN report cites an August 2017 study by UNAM and UAM researchers that found transgenes in 82% of 367 processed food and corn product samples in Mexico, including 90.4% of tortillas tested. The same study detected glyphosate in nearly one-third of the transgene-positive samples. The report frames the findings as a food sovereignty and health concern.
