As insect farming grows to meet demand for sustainable protein, evidence is accumulating that insects may be capable of experiencing pain and suffering, raising important welfare questions.
The welfare status of farmed insects is deeply uncertain. Evidence suggests some insect species have nociceptors and respond protectively to noxious stimuli, suggesting at minimum nociception and possibly something like pain. Given the billions of insects farmed, even a small probability of sentience creates significant welfare stakes. Current practices focus on rapid growth and high density with little consideration of insect-specific needs or humane slaughter methods.
