Did you know?...For a food to be certified as organic by the government, it must be grown without artificial pesticides and fertilizers. Milk, meat, poultry and eggs are designated as organic if they are not treated with hormones or antibiotics. (Hormones make animals larger; antibiotics keep them disease-free.) In addition, food can't be labelled organic if it is genetically altered or irradiated (processed with radiation to kill harmful germs).
