Insect Farming Welfare: Emerging Standards

Insect farming is growing rapidly as a sustainable protein source, raising welfare questions that welfare science is only beginning to address.

Key Facts

Billions of insects including black soldier fly larvae, mealworms, and crickets are farmed globally for food and feed
Insect sentience is scientifically uncertain but some research suggests basic nociceptive responses
The welfare footprint of insects per gram of protein is likely lower than that of vertebrate livestock
Standards for insect farming welfare are at the earliest stage of development globally

Welfare Considerations

Insect farming welfare occupies a frontier of animal welfare science where fundamental questions about sentience remain unresolved. Current evidence suggests that insects lack the neurological complexity for pain experience as understood in vertebrates, but evidence of nociceptive responses and behavioral changes in response to noxious stimuli creates enough uncertainty to warrant precautionary consideration. The scale of insect farming — billions of individuals per facility — means that even small welfare improvements per individual could have significant aggregate effects. Precautionary welfare principles suggest minimizing unnecessary stress, providing appropriate temperature and nutrition, and using killing methods that achieve rapid death.

What You Can Do

Support research into insect sentience and welfare to improve the evidence base for standards
Engage with insect farming industry on developing precautionary welfare guidelines
Consider insect-derived protein as a potentially lower-welfare-footprint alternative to vertebrate meat
Advocate for inclusion of insect welfare in broader animal welfare legislation as evidence develops
