GM strains found in Mexican corn plantings


Genetically modified (GM) corn is contaminating some of Mexico’s corn crops, the government has confirmed. Mexico’s Environment and Natural Resources Ministry (Semarnat) made the announcement on Sept. 18 after its scientists had verified the results of a small study by Ignacio Chapela, a biologist at the University of California, Berkeley. Of 22 fields sampled in the southwestern state of Oaxaca, 13 had between 3% and 10% of corn grains containing bioengineered genes and two others registered more than 10%, Semarnat reported. “This is a biological invasion, not by an organism but by a gene sequence,” says Exequiel Ezcurra, president of the National Ecology Institute (INE), the Semarnat scientific agency that carried out the tests. Some fear that transgenic corn could threaten a virtual genetic library... [Log in to read more]
