The national organic program rules prohibit the use of conventional pesticides, petroleum- or sewage-sludge-based fertilizers, bioengineering or ionizing radiation and synthetic substances. Foods certified as organic must be produced using growing methods that minimize soil erosion and that maintain or enhance the fertility of the soil.
Organic farms need to prove that these materials have not been used for at least three years. Organic meat, poultry, eggs and dairy products come from animals that are given no antibiotics or growth hormones, must be fed organic feed and have access to the outdoors. Before a product can be labeled "organic," an inspector visits the farm where the food is produced to make sure the farm meets USDA standards.
