The U.S. Department of Agriculture has put in place a set of national standards that food labeled "organic" must meet, whether it is grown in the United States or imported from other countries. Organic meat, poultry, eggs, and dairy products come from animals that are given no antibiotics or growth hormones. Organic food is produced without using most conventional pesticides; fertilizers made with synthetic ingredients or sewage sludge; bioengineering; or ionizing radiation.
