Shrimp Slaughter Welfare: Current Practice and Alternatives

Billions of shrimp are slaughtered annually without any stunning or humane killing, making shrimp slaughter one of the largest-scale welfare problems in food production.

Key Facts

Over 400 billion farmed shrimp are produced globally each year
Most shrimp are killed by boiling, ice slurry, or direct freezing while conscious
Shrimp can detect and respond to noxious stimuli including heat
The sentience of shrimp has been subject to increasing scientific scrutiny
Few commercial facilities have adopted any stunning protocols for shrimp

Welfare Considerations

The rapid death of shrimp by boiling causes intense thermal nociception responses before death. Ice slurry methods induce a slower cooling that does not quickly induce insensibility, potentially causing prolonged cold-stress suffering. Shrimp display pain-avoidance behaviours and have the neural machinery for nociception. While scientific consensus on shrimp sentience is not definitive, the precautionary principle applied to billions of individuals makes welfare-better slaughter methods a significant ethical priority.
