Primate Research: Welfare in Scientific Settings

Non-human primates used in research face significant welfare challenges. Understanding the regulatory framework and the scale of the issue informs advocacy for better protections.

Key Facts

Approximately 60,000-70,000 primates are used in research in the EU annually
Macaques are the most commonly used research primates, followed by marmosets
Directive 2010/63/EU requires 3Rs application and sets minimum housing standards
Social housing is required for primates in EU research institutions
The UK requires retrospective harm assessment for all research involving primates

Welfare Considerations

Research primates endure multiple welfare challenges: captivity stress, social disruption when moved between facilities, experimental procedures including blood sampling, dosing, and surgery, and the permanent loss of wild-type behaviour. Social isolation — historically common — causes severe psychological harm in social primates. Modern standards require social housing, complex environments, and positive reinforcement training to reduce procedure-related stress. Regulatory oversight has improved significantly in Europe, but global standards vary enormously.

What You Can Do

Support the development and regulatory acceptance of alternatives to primate research
Donate to organisations like FRAME that fund non-animal method development
Advocate for higher welfare standards in countries with weaker primate research regulations
Engage with medical research charities to ask about their commitment to replacing primate research
Stay informed about regulatory reviews of primate research and participate in consultation processes
