Root Cause

Since March 1, 2018, Article 178 of the Tierschutzverordnung (TSchV, SR 455.1) requires that crustaceans (Panzerkrebse) such as lobsters be stunned - the Federal Food Safety and Veterinary Office (BLV) recommends electrical stunning - before being killed; boiling a live, unstunned crustacean is an explicitly cited example of a prohibited killing method and can be treated as animal cruelty under the Tierschutzgesetz. Transporting or storing live crustaceans on ice or in ice water is also forbidden; they must be kept in their natural environment (e.g. seawater) and killed or tanked within a limited time of arrival. The rule is not limited to restaurants or fishmongers - the underlying cruelty prohibition applies broadly to anyone killing the animal.

Workarounds

  1. 85% success Stun the crustacean with an electric stunning device immediately before killing it (BLV's recommended method), or buy it pre-stunned/pre-killed from a retailer that already complies 
    BLV's technical guidance (Fachinformation 16.8) describes correct electrical stunning parameters; mechanical destruction of the brain is accepted but BLV advises avoiding it where possible in favor of electric stunning.

Dead Ends

Common approaches that don't work:

  1. Cook a live lobster or other crustacean by dropping it straight into boiling water without stunning it first, whether at home or in a restaurant 85% fail

    TSchV Art. 178 requires that crustaceans, like vertebrates, only be killed under stunning; BLV explicitly names immersion in boiling water without prior stunning as a prohibited, painful killing method, backed by the Tierschutzgesetz's general animal-cruelty penalties (fines or up to three years' imprisonment for cruel killing).

  2. Store or transport a live lobster on ice or in ice water before cooking 60% fail

    BLV guidance states transport or storage of live crustaceans on ice or in ice water is forbidden because it is considered inhumane; animals must be kept moist in their natural environment and either killed properly or moved to a suitable holding tank within 12 hours of arrival.
