I am delighted to see the red, white and blue signs appearing in front of some of the foods in our local Thriftway store. They say “NON GMO.”

About 80 percent of our processed foods contain GMOs — genetically modified organisms. Their potential impact on human health is unknown.

At least 30 countries have banned genetically engineered product because of the risks to human health and the environment. In the U.S., however, not only are they allowed in our food supply, but manufacturers are not even required to identify or label a GMO ingredient in their products.

When President Obama was on the campaign trail in 2007, he pledged to uphold the labeling of GMO foods if elected president, saying “because Americans should know what they’re buying.”

That promised labeling is not taking place. Thank you to the Thriftway management for their efforts to inform us which foods are GMO-free.
