LOS ANGELES —
The Food and Drug Administration does not require genetically modified foods to carry a label, but organic food companies and some consumer groups have intensified their push for labels, arguing that the modified seeds are floating from field to field and contaminating traditional crops. The groups have been bolstered by a growing network of consumers who are wary of processed and modified foods.
The U.S. Senate this week overwhelmingly rejected a bill that would allow states to require labeling of genetically modified foods.
The Biotechnology Industry Organization, a lobbying group that represents Monsanto, DuPont & Co. and other makers of genetically modified seeds, has said that it supports voluntary labeling for people who seek out such products. But it says that mandatory labeling would only mislead or confuse consumers into thinking the products aren’t safe, even though the FDA has said there’s no difference between GMO and organic, non-GMO foods.
However, state legislatures in Vermont and Connecticut moved ahead this month with votes to make food companies declare genetically modified ingredients on their packages. And supermarket retailer Whole Foods Markets Inc. has said that all products in its North American stores that contain genetically modified ingredients will be labeled as such by 2018.
Whole Foods says there is growing demand for products that don’t use GMOs, with sales of products with a “Non-GMO” verification label spiking between 15 percent and 30 percent.
