A "March Against Monsanto" was held Saturday at the Tempe Farmer's Market near Ash Avenue and University Drive.
The group gathered to protest a federal bill written by Monsanto, which is a global herbicide company. The bill would ban states from passing GMO labeling laws.
"Basically, they're instilling GMOs... genetically modified organisms... basically, frankenfood, we don't know what it is; how it's going to react to our bodies...," said Jeremy Nolt, a protester.
Congress will hold its first vote on HR 1599 next month. Critics are calling it the "Dark Act" or "Denying Americans the Right to Know" Act.
