Laboratory Primate Welfare and Retirement

Non-human primates used in biomedical research have complex social and psychological needs that standard laboratory housing often fails to meet, and face uncertain futures after research ends.

Key Facts

The US uses approximately 65,000 non-human primates in research annually
Social isolation — common in research settings — causes severe psychological distress in social primates
Many research facilities lack sanctuary placement pathways for primates at end of study
Environmental enrichment requirements exist but implementation quality varies widely

Welfare Considerations

Primates are among the most welfare-challenged laboratory animals due to their cognitive complexity and strong social bonds. Solitary housing causes depression-like states, self-injurious behavior, and stereotypies. Post-research retirement to accredited sanctuaries is widely viewed as the gold standard but requires institutional commitment and funding.

What You Can Do

Support accredited primate sanctuaries that provide retirement for research animals
Advocate for Three Rs implementation in primate research funding decisions
Urge research institutions to publish data on primate welfare outcomes
Support legislation requiring post-research retirement programs at institutions using primates
Fund development of non-primate alternatives to research requiring primates
