Shrimp Welfare at Slaughter | Animal Welfare Hub

Evidence and debate around shrimp sentience and the case for humane slaughter methods.

Key Facts

Hundreds of billions of shrimp are farmed and killed annually, making their welfare among the most numerically significant
Shrimp have nociceptors and show protective responses to damaging stimuli
The UK Animal Welfare Act 2022 included decapod crustaceans as sentient beings based on a Birch review
Common killing methods include boiling alive, mechanical cutting, or temperature shock — all without prior stunning
Electrical stunning of shrimp has been developed and shown to render them insensible before killing
Consumer awareness of shrimp welfare is low relative to the scale of the industry

Welfare Considerations

Shrimp welfare at slaughter represents one of the largest-scale potential welfare problems in the food system given the extraordinary numbers involved. Evidence for shrimp sentience is not conclusive but is sufficient under the precautionary principle to warrant efforts to minimize potential suffering at slaughter. Electrical stunning methods that render shrimp insensible before killing have been developed and are technically feasible at commercial scale. The UK's legislative recognition of decapod crustacean sentience has created policy precedent that other jurisdictions are beginning to consider. Consumer and industry awareness of this issue is the first step toward meaningful change.
