England's 2000 ban on mink farming ended an industry causing serious animal welfare harm. The welfare legacy includes escaped feral mink threatening native wildlife and the remaining question of humane management.
The mink fur farming ban eliminated an industry causing severe welfare harm - mink in wire battery cages showed high rates of self-injurious behaviour and stress indicators consistent with chronic frustration of natural behaviours. The welfare legacy, however, includes the ongoing management of feral populations through trapping. Live trap and kill programmes protect native species welfare at the cost of individual mink welfare - an invasive species management trade-off. Humane trap standards and rapid kill methods minimise individual suffering. The ban itself has been replicated across Europe, demonstrating positive policy diffusion for animal welfare.
