Insect farming for food and feed is growing rapidly as a sustainable protein source, but the welfare status of farmed insects remains scientifically and ethically contested. What does the evidence say?
Insect welfare represents a frontier question where scientific uncertainty has profound welfare implications given the enormous scale of insect farming. The precautionary approach to insect welfare recognizes that uncertainty about sentience does not eliminate moral concern - if there is a meaningful probability that insects experience suffering, the trillions of insects in commercial farming globally represent a massive potential welfare problem. A welfare-conscious approach to insect farming would prioritize species selection based on welfare risk (less likely sentient species preferred), develop and apply more humane slaughter methods regardless of certainty about sentience, and invest in research to resolve scientific uncertainty. Consumer awareness of insect welfare considerations is also increasing as insect products enter mainstream food markets.
