As insect farming scales up as a sustainable protein source, questions about insect sentience and welfare are becoming increasingly important for ethical and regulatory consideration.
The welfare status of farmed insects is uncertain but the potential scale of suffering is enormous given that billions of insects are produced daily. Evidence suggests insects have nociceptors and can respond to harmful stimuli, though whether they have subjective experiences remains debated. Given this uncertainty, the precautionary principle suggests adopting welfare standards even without definitive proof of sentience. Basic welfare measures including appropriate temperature, nutrition, and humane slaughter are feasible and ethically prudent.
