Frequently Asked Question
Animal Welfare“Humane slaughter”
Last reviewed: January 9, 2026
Summary
Stunning can reduce suffering when properly applied, but failures occur and transport/handling before slaughter can be stressful. Even “best case” slaughter ends the animal’s life far earlier than natural lifespan, which many ethical frameworks consider significant harm.
Evidence Summary
- Welfare risk points: transport, lairage, handling, stunning effectiveness, line speed. Evidence quality: Moderate Limitations / nuance: The ethical conclusion (“killing is harm”) is philosophy; the factual claim is that welfare risks exist and oversight varies. Bottom line: “Humane slaughter” reduces but does not eliminate welfare concerns, and it doesn’t address the ethical issue of killing.
