The rapid growth of insect farming for food and feed raises novel welfare questions, as billions of insects are reared and processed under conditions whose welfare implications are still being scientifically evaluated.
Insect welfare sits in a zone of genuine scientific and ethical uncertainty. While insects lack the complex neurological structures associated with mammalian suffering, recent research demonstrates nociceptive responses and behavioral avoidance of harmful stimuli. Given the enormous scale of insect farming - trillions of animals - even small probabilities of morally significant suffering warrant precautionary welfare standards. Chilling to immobility before processing is emerging as a welfare-sensitive slaughter approach.
