DENVER — A move to require the labeling of genetically modified food found little traction with Colorado voters.

Just 33 percent of the 1.8 million votes counted supported Proposition 105. As of 3 a.m., 1,196,971, or about 67 percent, voted no.

Proposition 105 would require any “prepackaged, processed food or raw agricultural commodity that has been produced using genetic modification” to include the label: “Produced with genetic engineering.”

Supporters of the proposition, including Chipotle Mexican Grill and Whole Foods grocery stores, say it’s a commonsense move that would give residents more information about the foods they eat every day. Proponents note that dozens of other countries, including all of the European Union, already require similar food labels.

Opponents, including many state-level farmers’ trade groups, worry that Proposition 105 could raise food producers’ costs, forcing them to increase consumer prices on their goods. They also worry that the label could put them at a disadvantage when selling Colorado-made goods in other states that have no GMO labelling requirements.

Opponents also object on the grounds that the GMO label would make some consumers avoid the foods, even though there is no conclusive evidence that GMO foods are more dangerous than non-GMO products.
