The common practice of boiling live crabs is increasingly under scrutiny as evidence accumulates for crab nociception and the likelihood of a painful death experience.
The precautionary case for ending live boiling of crabs is strong: behavioral evidence for nociception is accumulating, the cost of stunning before boiling is minimal, and the potential for preventing suffering is large given the billions of crustaceans boiled annually. Mechanical stunning tools for crabs and lobsters exist and are affordable. The ethical asymmetry is clear — if crabs do suffer, live boiling causes immense preventable pain; if they do not, stunning adds nothing but a small cost. Regulatory moves in Europe are establishing a welfare standard that other jurisdictions should follow.
