Conventional maize contaminated with genetically modified material has been detected in nine Mexican states, according to Liza Cervantes Torres, coordinator of the Genetic Engineering Campaign at Greenpeace Mexico.

Torres revealed the findings at a meeting of farmers’ organisations, environmentalists, local people and scientists about problems facing the maize industry. The meeting called on Mexican authorities to limit the growing of GM maize in Mexico and encourage organic maize farming, reported the Latin American News Digest.

The contaminated maize was found in the highest volumes in Chihuahua, the Federal District, Hidalgo, Oaxaca, Puebla, Tlaxcala and Veracruz,
