Insect farming is growing rapidly as a sustainable protein source, but welfare questions about the capacity of farmed insects to suffer require evidence-based frameworks for humane rearing.
Insect farming welfare sits at the frontier of applied welfare science - uncertainty about insect sentience meets the reality of trillions of individual animals being reared in industrial systems. The scale means that even a low probability of morally relevant suffering implies enormous total welfare stakes. Responsible insect farming approaches this uncertainty by adopting practices that minimise suffering risk: appropriate temperature management, clean environments, humane killing methods that cause rapid death, and research into whether welfare indicators differ across different rearing conditions. The welfare precautionary principle - minimising suffering where practical even under uncertainty - is particularly applicable at insect scale given the numbers involved.
