Lobsters are routinely transported and killed alive in restaurant kitchens worldwide. The growing evidence for crustacean sentience has driven calls for more humane practices that are increasingly being adopted.
The evidence for lobster sentience has progressively strengthened the welfare case against boiling alive. Behavioral studies show that lobsters remove themselves from noxious stimuli and learn to avoid locations where they received shocks - consistent with pain experience. The escape behavior and physical signs of distress during boiling suggest acute suffering. The time to death from boiling - potentially several minutes in a large lobster - is a significant welfare concern given the evidence for nociception. The UK's recognition of decapod crustaceans as sentient in the Animal Welfare (Sentience) Act 2022 creates a framework for extending welfare protections, though legislation specifically requiring humane slaughter of lobsters is not yet in force. Restaurant industry adoption of CrustaStun and spike killing is growing but remains minority practice.
