In the United States, any public animal exhibit must be licensed and inspected by the
United States Department of Agriculture,
United States Environmental Protection Agency,
Drug Enforcement Administration,
Occupational Safety and Health Administration, and others. Depending on the animals they exhibit, the activities of zoos are regulated by laws including the
Endangered Species Act, the
Animal Welfare Act, the
Migratory Bird Treaty Act of 1918 and others. Additionally, zoos in North America may choose to pursue accreditation by AZA. The American association has developed a definition for zoological gardens and aquariums as part of its accreditation standards: "A permanent cultural institution which owns and maintains captive wild animals that represent more than a token collection and, under the direction of a professional staff, provides its collection with appropriate care and exhibits them in an aesthetic manner to the public on a regularly scheduled basis. They shall further be defined as having as their primary business the exhibition, conservation and preservation of the earth's fauna in an educational and scientific manner." To achieve accreditation, a zoo must pass an application and inspection process and meet or exceed AZA's standards for animal health and welfare, fundraising, zoo staffing, and involvement in global conservation efforts. Inspection is performed by three experts (typically one veterinarian, one expert in animal care, and one expert in zoo management and operations) and then reviewed by a panel of twelve experts before accreditation is awarded. This accreditation process is repeated once every five years. AZA estimates that there are approximately 2,800 animal exhibits operating under USDA license as of 2019; fewer than 10% are accredited. Certification is possible for facilities that hold animals, but are not regularly open to the public. == Saving Animals From Extinction ==
