Zoo Accreditation and Animal Welfare Standards

Accreditation systems for zoos vary widely in their welfare standards, and many facilities holding animals do not meet basic welfare criteria.

Key Facts

The US has approximately 800 licensed animal exhibitors but only 238 AZA-accredited zoos
AZA accreditation requires welfare-focused standards but covers less than 10% of exhibitors
Many roadside zoos and petting zoos operate with minimal welfare oversight
AZA-accredited zoos contribute over $230 million annually to conservation programs
Animal welfare science has advanced significantly faster than zoo standards have updated

Welfare Considerations

The zoo industry encompasses a vast range of institutions with vastly different welfare standards. Accredited facilities generally provide better care and contribute to conservation, but even the best zoos cannot meet the full needs of species like elephants, great apes, and polar bears. Many facilities without accreditation provide genuinely poor welfare. Supporting high-quality accredited institutions while opposing roadside zoos and poorly managed facilities is a nuanced but important welfare position.

What You Can Do

Visit only AZA or equivalent accredited zoos and aquariums when supporting animal exhibits
Research facilities thoroughly before visiting, looking for welfare red flags
Avoid roadside zoos, petting zoos with exotic animals, and unaccredited exhibits
Support accredited zoos with strong welfare and conservation programs
Advocate for stronger government oversight of all animal exhibition facilities
