Because of the lack of interest of federal government to protect the large diversity of Mexican maize against the contamination of GM crop, Michoacán State congress passed by a majority the ”Law of Promotion and Protection of Native Maize as Alimentary Patrimony of Michoacán State”, which will allow the protection of 18 of the 59 races of this crop that exist in Mexico. [...] Michoacán’s initiative follows the recent approval of the ”Law of Promotion and Protection of Native Maize as an original patrimony, in constant diversification, and alimentary for Tlaxcala State”.
