Mass culling of millions of animals during foot and mouth disease outbreaks raises acute welfare concerns about methods, speed, and the necessity of preventive slaughter.
Foot and mouth disease outbreaks create acute welfare emergencies in which the speed and scale of required culling exceed the capacity to maintain humane standards. Emergency slaughter conditions — field killing rather than certified slaughterhouses, undertrained staff, equipment shortages — produce higher rates of ineffective stunning and prolonged death. The policy choice to cull rather than vaccinate is primarily driven by trade economics rather than animal welfare, and welfare advocates have consistently argued that vaccination with targeted culling of clinically affected animals is both more humane and more effective.
