The rapid growth of insect farming requires attention to harvesting methods that minimize potential suffering.
Insect harvesting method matters enormously given the scale of insect farming. If insects have any meaningful capacity for pain or distress, then harvesting methods that cause rapid unconsciousness and death represent a welfare improvement over those that cause prolonged suffering before death. Cold stunning — reducing body temperature until insects are immobile — before freeze-killing is currently considered the most welfare-positive approach under scientific uncertainty, as it minimizes the duration of any potentially adverse experience. The enormous numbers involved mean that even small differences in per-animal welfare impact translate to enormous aggregate effects across the production cycle.
