Several leading U.S. farm groups are urging food companies to think twice about their sustainability goals, saying they may actually be causing more harm than good. The groups, including the American Farm Bureau Federation, are responding specifically to Dannon's pledge to eliminate genetically modified ingredients from its yogurt products, which they noted was just the latest such promise from prominent food manufacturers and retailers in recent years. In a letter sent today to Mariano Lozano, head of Dannon's U.S. operations, the farm groups said the company's strategy to eliminate GMOs (genetically modified organisms) "is the exact opposite of the sustainable agriculture that you claim to be seeking,” adding: “Your pledge would force farmers to abandon safe, sustainable farming practices that have enhanced farm productivity over the last 20 years while greatly reducing the carbon footprint of American agriculture." Other groups signing on to the letter were the American Soybean Association, the American Sugarbeet Growers Association, the National Corn Growers Association, the National Milk Producers Federation, and the U.S. Farmers and Ranchers Alliance. In a news release, the groups say they agree that biotechnology plays an important role in reducing the environmental footprint of agriculture, and challenged as disingenuous the assertion that sustainability is enhanced by stopping the use of GMO processes. "This is just marketing puffery, not any true innovation that improves the actual product offered to consumers," said Randy Mooney, chairman of the National Milk Producers Federation, and a dairy farmer from Rogersville, Missouri. "What's worse is that removing GMOs from the equation is harmful to the environment - the opposite of what these companies claim to be attempting to achieve."
