The rapid growth of insect farming for food and feed raises important and unresolved questions about the sentience and welfare of farmed insect species.
The welfare status of farmed insects is one of the most contested questions in animal welfare science. Neurological complexity varies significantly between species, and the evidence for subjective experience in most farmed insects remains limited but not absent. Given the enormous scale of insect farming — billions of individuals per facility — even a small probability of suffering translates to potentially significant welfare impacts. The precautionary principle suggests that research into humane slaughter methods, stocking densities, and environmental conditions should proceed alongside commercial scaling.
