As insect farming scales rapidly to provide sustainable protein, welfare questions about insect sentience and farming conditions are receiving growing scientific attention.
Insect farming presents novel welfare questions: the sheer scale (billions of individuals per facility) combined with scientific uncertainty about insect sentience creates both high-stakes and high-uncertainty welfare considerations. The precautionary principle suggests investing in welfare research and adopting practices that minimize potential suffering even before certainty is established. Current areas of concern include overcrowding causing injury and disease, slaughter methods that may involve prolonged thermal stress, and substrate conditions that prevent natural behaviors. Emerging welfare standards focus on stocking density limits, substrate enrichment, and rapid slaughter methods. The establishment of welfare norms for insects now, while the industry is young, is far more tractable than retrofitting standards onto a mature industry.
