According to the United States Department of Agriculture (USDA): “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.” Food produced in this way can be labeled with the USDA symbol and sold as ‘organic.’  Source: fyi.extension.wisc.edu
