Conacyt, Mexico's science council, warned that glyphosate is present in a third of the corn tortillas consumed in Mexico. The agency described the herbicide as teratogenic and carcinogenic and linked it to GM crops.
It urged government agencies to separate science policy from corporate interests.
The warning is a health and policy statement with no announced restriction on corn or glyphosate. It is unlikely to move corn prices in the near term but could increase pressure on GM corn and glyphosate use over time.
After 1,623 past policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
