Mink Farming Welfare Science 2025

The welfare evidence for phase-out of one of the most criticized forms of animal agriculture

Overview

Approximately 30-40 million American mink (Neovison vison) are killed annually for fur, primarily in Denmark, China, Poland, the Netherlands (now phased out), and other European countries. Mink are semi-aquatic carnivores with large natural territories; their confinement in small wire cages causes severe behavioral deprivation and chronic stress. The welfare evidence against mink farming is among the most extensive for any farmed species.

⚠️ Standard mink cage: 900 cm² — natural territory is several kilometers in all directions

⚠️ Stereotypic behaviors affect 30-80% of farmed mink depending on system — among the highest rates of any farmed species

Welfare Evidence

Research from Denmark, Finland, Sweden, and the UK has comprehensively documented mink welfare problems:

Stereotypic pacing: Repetitive back-and-forth movement for hours daily — indicator of severe psychological distress
Self-injurious behavior: Tail-biting, self-mutilation in significant minority of animals
Lack of water access: Many farms provide only drinking water; mink swim in the wild; water access significantly improves welfare
Killing methods: Carbon dioxide or anal electrocution; both cause stress and pain unless performed correctly

✓ Water access provision: reduces stereotypic behaviors by 20-40%; strongly preferred by mink

COVID-19 & Industry Crisis

Mink farms became major COVID-19 reservoirs in 2020-2021. Denmark culled its entire national mink herd (17 million animals), the largest single animal culling event in history. Netherlands, Spain, Italy, Greece, and France all experienced significant outbreaks and culls. The public health crisis accelerated already-growing political pressure for phase-outs. Netherlands banned mink farming from 2024; France from 2025. Multiple other European countries have bans in progress.
