Precautionary welfare considerations suggest that insect harvest methods should minimize potential suffering even in the absence of certainty about insect sentience.
Under uncertainty about insect sentience, applying precautionary welfare principles suggests using harvest methods that would minimize suffering if insects do experience pain. Cold stunning that reduces metabolic activity before killing may be preferable to immediate grinding. As evidence on insect sentience develops, harvest method guidelines should evolve to reflect the best available science rather than assuming insects cannot suffer.
