Mexico is the center of origin for maize, and there is a substantial interest in protecting the genetic integrity of this limited resource. At the same time Mexico’s population is growing, and farmers potentially find utility in growing genetically-engineered corn, as resistance to insects and lower pesticide use are attractive traits. There is an intricate balance between feeding a population and ensuring farmer profit versus preservation of a genetic resource. In this week’s podcast Dr. Paul Vincelli (@pvincell) interviews Dr. Sol Ortiz Garcia, the Commission on Biosafety of Genetically Engineered Organisms. How much GE maize is cultivated in Mexico? Is it a threat? Is there evidence of transgene flow from imported feed? These are important questions, as the topic of genetic integrity of natural populations is a frequent area of discussion and debate.
