I do not think we will know if that food we feed our birds has genetically altered ingredients unless we make our bird's food from scratch. Just FYI the top 10 modified foods are: rice, grains, Papaya and Banana, Artificial additives, preservatives and sweeteners, Potatoes, Corn, Tomatoes, Squash, Oils, Salmon, Peas, Alfalfa, Pork and Honey.
