Laboratory Primate Welfare Standards

Non-human primates used in research face unique welfare challenges due to their high cognitive complexity.

Key Facts

Over 70,000 non-human primates are used in research annually in the US
Chimpanzees were retired from US federal research in 2015 and are protected under the Chimp Act
Social housing is required for non-human primates under current welfare standards
Primates in research can develop psychological distress including self-harm behaviors

Welfare Considerations

Non-human primates used in biomedical research have cognitive and social complexity that creates unique welfare challenges. Isolation — historically common in primate research — causes severe psychological distress in species that live in complex social groups in the wild. Current welfare standards require social housing and environmental enrichment, but implementation varies. The retirement of chimpanzees from federal research reflects the recognition that some species cognitive complexity makes research use ethically unjustifiable regardless of welfare conditions.

What You Can Do

Support legislative protections for great apes and other cognitively complex primates
Advocate for accelerated development of non-primate research alternatives
Support accredited sanctuaries housing retired research primates
Engage with research institutions on their primate welfare policies and enrichment programs
