Primate Welfare in Biomedical Research

Non-human primates used in biomedical research have complex social, cognitive, and psychological needs that create serious welfare challenges in laboratory settings.

Key Facts

Approximately 70,000 non-human primates are used in research globally each year
Macaques make up the majority of research primates, followed by marmosets
Social isolation causes severe psychological distress in primates; pair or group housing is preferred
Environmental enrichment including foraging opportunities is essential for primate welfare
The 3Rs framework (Replace, Reduce, Refine) guides efforts to minimize primate research use

Welfare Considerations

Primates in research settings face multiple welfare challenges: social isolation, restricted movement, repeated handling and procedures, and deprivation of species-typical behavioral opportunities. Even with enrichment programs, laboratory environments cannot fully meet the needs of animals adapted to complex forest habitats with rich social lives. Chronic stress from these conditions causes behavioral abnormalities including self-injurious behavior and stereotypies. The 3Rs approach and investment in alternative methods are essential responses.

What You Can Do

Support organizations developing and validating non-animal research alternatives
Advocate for mandatory environmental enrichment and social housing standards for research primates
Choose health and beauty products certified as not tested on animals
