This report comprises key ﬁndings and recommendations to the CEC Council concerning maize and genetic diversity in Mexico.
When it was reported in 2001 that genetically modiﬁed corn had spread among native maize land races in the high valleys surrounding Oaxaca, the familiar controversy and debate over genetically modiﬁed, or transgenic, crops suddenly took root in Mexico.
More recently, testing sponsored by the government of Mexico has conﬁrmed the appearance of transgenic material in the maize ﬁelds of the Sierra Norte region and elsewhere.
Peasant farmers and many others know that open-pollinated plants like maize easily share their genes, so they were naturally concerned with questions about the effects of transgenes.
In 2002, members of Mexican civil society, international organizations and, in particular, indigenous and peasant groups from Oaxaca, requested that the CEC Secretariat initiate an independent enquiry to determine the facts.
