"Food companies big and small are struggling to replace genetically modified ingredients with conventional ones.
Pressure is growing to label products made from genetically modified organisms, or "G.M.O." In Connecticut, Vermont and Maine, at least one chamber of the state legislature has approved bills that would require the labeling of foods that contain genetically modified ingredients, and similar legislation is pending in more than two dozen other states. This weekend, rallies were held around the globe against producers of genetically altered ingredients, and consumers are threatening to boycott products that are not labeled.
And so, for many businesses, the pressing concern is just what it will take to gain certification as non-G.M.O."
