Insect Welfare in Farming for Food and Feed

Insect farming is growing rapidly as a sustainable protein source, raising novel welfare questions about invertebrate sentience.

Key Facts

Global insect production for food and feed is expected to reach 500,000 tonnes by 2030
Common farmed species include black soldier fly, mealworm, and house cricket
Evidence for insect sentience is limited but cannot be ruled out given their neural complexity
Stress responses and nociceptor-like systems have been identified in some insect species
Current insect farming involves enormous numbers of animals per unit of production

Welfare Considerations

The scale of insect farming means that even modest probabilities of sentience translate to significant potential welfare impacts across trillions of animals. A precautionary approach to insect welfare, including investigation of humane slaughter methods and optimal housing conditions, is appropriate given current scientific uncertainty.

What You Can Do

Support research into insect sentience, cognition, and welfare
Advocate for welfare standards to be considered in insect farming regulation
Engage thoughtfully with the welfare implications of insect-based protein
Support the development of humane slaughter methods for farmed insects
