6 places where genetically engineered crops are banned by Laura Lorenzetti @FortuneMagazine April 27, 2015, 4:27 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons Chipotle CMG has officially become one of the first major restaurant chains to erase genetically modified ingredients from its menus. GMOs, as they’re known, are a source of ongoing debate about their impact on human health. A GMO is any food product whose genetic material has been tweaked using genetic engineering techniques. This can be done in animals, bacterial, plants and crops. The idea is that altering the DNA can make certain items stronger and more productive. For example, crops are modified to better resist drought, pesticides or insects. GMOs are widespread. Up to 93% of corn, 94% of soybeans and 96% of cotton in the U.S. are genetically altered. The safety debate rages between one group, which includes manufacturers like Monsanto MON and some farmers, that say these seeds are scientifically proven to be safe and are irreplaceable due to their hardiness. Others, like the Institute for Responsible Technology, say GMOs are dangerous to human health and lack much government regulation–at least in the U.S. Many other countries and cities, however, have taken action to limit or altogether ban GMOs. Here’s a list of some of the growing number of areas that are limiting the reach of genetically engineered crops.
