Abstract At least 200 billion black soldier fly ( Hermetia illucens ) larvae (BSFL) are reared each year as food and feed, the insect farming industry is projected to grow rapidly. Despite interest by consumers, producers, legislators, no empirical evidence exists guide producers in practicing humane – or instantaneous slaughter for these novel mini-livestock. BSFL may be slaughtered via freezing, boiling, grinding, other methods; however standard operating procedures (SOPs) equipment design affect likelihood of death using methods. We tested how larval body size particle plate hole diameter that a meat grinder. Larval did not 106–175 mg mass. However, had significant effect on death, with only 54% experiencing an instant when largest (12-mm diameter) compared 84% smallest (2.55 mm). higher percentage (up 99%) could achieved reducing proportion become stuck machine. conclude outlining specific recommendations support achieving 99% rate through SOPs used similarly designed machines. also develop protocol wish test their own grinding SOPs.

While insects are already the largest group of terrestrial food and feed livestock animals in terms absolute number individuals, insect farming industry is expected to continue growing rapidly order meet nutritional demands human population during 21st century. Accordingly, consumers, producers, legislators, industry-adjacent researchers have expressed interest further research assessment farmed welfare. Operational indicators animal welfare those that can be used putatively assess absence true affective state (e.g., valenced/emotional state) commonly for vertebrate species; however, significant behavioral physiological differences between vertebrates means these must examined their correctness, usefulness, feasibility prior use with livestock. The most valuable operational would (1) correctly correspond insect's putative state; (2) provide useful information about what affecting welfare; (3) feasible deployment at a large scale on farms. As there many possible could researched insects, evaluating likely feasibility, usefulness will allow prioritize which investigate first Thus, this review, we explore whether or somatic welfare, including whole-body, immune, neurobiological, respiratory/cardiac indicators, may correct, feasible, assessing We review systems, as well any existing, welfare-relevant data from closely related insects. end by proposing priority list physiological, correctly, usefully, feasibly guide indicator validation priorities scientists.

It is widely accepted that we ought to avoid taking excessive risks of causing gratuitous suffering. The practical implications this truism, however, depend on how understand what counts as an risk. Precautionary frameworks help us decide when a risk exceeds the threshold for action, with recent Birch et al. (2021) framework assessing invertebrate sentience being one such example. uses four neurobiological and behavioural criteria provide evidence-based standard can be used in determining precautionary action promote welfare may warranted. Our aim discussion paper new motivation approach represents while simultaneously identifying some possible revisions reduce false positives without abandoning framework's objectives.
