Insect farming is expanding rapidly as a sustainable protein source, raising important and unresolved questions about whether farmed insects have the capacity to experience suffering.
Insect farming welfare sits in philosophically uncertain territory, as the scientific evidence for insect sentience is genuinely contested. The precautionary principle suggests that where there is meaningful uncertainty about capacity for suffering, some level of welfare consideration is warranted. Practical welfare measures for farmed insects include maintaining appropriate temperature ranges, providing suitable substrate for natural behavior, avoiding extreme crowding, and using rapid killing methods at slaughter. Research into insect nociception and aversive learning continues to evolve, and industry standards should be designed to update as scientific understanding improves. The scale of insect production means the welfare stakes are enormous even if individual insect sentience is modest.
