More than half of US states introduced bills aimed at requiring GMO labeling last year, in a country where 80 percent of the food contains ingredients that were made with genetically modified organisms.
While only two states have passed such measures, and none have yet implemented any labeling requirements, farmers are concerned about the prospect.
"If each state had a different label requirement, our farmers just couldn't adapt to that and really economically grow safe, affordable food," Ray Gaesser, president of the American Soybean Association, which represents 600,000 US farmers, said yesterday.
Stressing the lack of scientific evidence that GMOs cause harm, Gaesser joined with corn farmers, bakers, restaurants, fisheries, animal feed and grocery store groups in forming the 30-member Coalition for Safe Affordable Food.
The umbrella group aims to "avoid unnecessary and confusing 50-state patchwork of GMO labeling laws," said Pamela Bailey, president and CEO of the Grocery Manufacturers Association.
Instead, members are calling for a federal solution that would only mandate GMO labeling "if the FDA, our nation's foremost food safety authority, determines that there is a health or safety risk," she told reporters.
Recognizing that some consumers want to know more about what is in the foods they eat, Bailey asked the FDA "to outline clear labeling standards that companies can use voluntarily."
Corn, soybeans and sugar beets have been genetically modified in the United States for many years, and farmers say these altered seeds are more resilient against pests and harsh weather.
Wheat is the only major crop that has not gained approval for genetic modification, as the prospect of GMO wheat faces resistance from foreign exporters, particularly in Asia.
