Farmed Guinea Pig Welfare in Andean Agricultural Systems

Guinea pigs have been farmed for food in the Andes for thousands of years and are increasingly recognised as a low-impact protein source with specific welfare requirements.

Key Facts

Guinea pigs (cuy) are a traditional food source in Peru, Bolivia, Ecuador, and Colombia, consumed for thousands of years
Global demand is growing as diaspora communities and food system sustainability advocates draw attention to cuy farming
Guinea pigs require group housing as highly social animals and suffer from isolation and single-housing practices
Traditional floor-level housing in family homes provides social housing but may lack ventilation and hygiene controls
Intensified cuy farming for export markets raises welfare concerns around stocking density and slaughter methods
Guinea pigs are prey species that mask illness, making welfare monitoring particularly important in farm settings

Welfare Considerations

Guinea pig farming occupies an interesting welfare space: as a lower-impact protein source than cattle or pigs, cuy farming could contribute to more sustainable food systems, but this benefit only holds if welfare standards are adequate. Guinea pigs are highly social animals whose welfare depends on appropriate group housing, proper nutrition, and low-stress environments. Slaughter methods in traditional contexts often lack pre-stunning, causing avoidable suffering. Welfare improvements should accompany any scaling of cuy production for international markets.

What You Can Do

Support welfare research into guinea pig housing and slaughter standards for intensified production
Engage with food system sustainability discussions that include welfare as a dimension alongside carbon impact
Advocate for humane slaughter requirements in any certification scheme for cuy meat products
Follow the work of organisations researching lower-impact protein sources with welfare standards
