CRABS, LOBSTERS AND UK ANIMAL WELFARE LAW

 

Animal welfare laws still do not apply to decapod crustaceans in the UK, despite new and compelling evidence that they are sentient and  feel pain. This  means that many of the ways of storing, handling and slaughtering crabs, lobsters, crayfish and prawns for the food industry may be causing intense suffering. Yet humane methods would be relatively straightforward to implement, as many examples of good practice show.

In November 2017 we published a preliminary study into lobster welfare in Animal Sentience Journal. We found that lobsters were frequently overcrowded, denied shelter, and subjected to unsuitably bright light. You can read it here

 

Other countries including New Zealand (1), Austria, Norway (2) and Switzerland (3) include decapod crustaceans in their animal welfare legislation in the food preparation and restaurant trade. Their decisions are based on scientific evidence  of their ability to feel pain and suffer, dating as far back as the 1990s; and they have largely taken a common sense approach to prevent unnecessary suffering where doubt still exists. For example:

 

  • the sale of live creatures to the general public is prohibited

  • chefs or other slaughterers must have a certificate of competence and prevent unnecessary suffering

  • decapods must be appropriately housed, in good quality water

  • they must be cared for in a way which prevents injuries and disease

  • their conditions must allow for ‘species-specific behaviour’

 

Yet in the UK, decapods are not classed as 'animals' under most legal defintions of the term. For example, the "WATOK"  (Welfare of Animals at the Time of Killing (England) Regulations 2015) do not  include any invertebrates under their definition of 'animal'. (However, since these regulations derive from the EU (Council Regulation (EC) No. 1099/2009) this is potentially up for revision following Brexit).

 

In addition the Animal Welfare Act of 2006 (England and Wales; together its with Scottish and Northern Irish counterparts) does not currently apply to catching, trapping, handling or storing of decapods. They can commonly be seen crammed together in barren restaurant tanks, awaiting slaughter. Subjected to noise, bright lighting, and with their claws bound, these naturally solitary animals may suffer from stress, injury, overheating and dehydration.

 

In November 2015, a Korean supermarket in Surrey was found to be selling live crabs pre-packaged in clingfilm; slowly suffocating and completely immobolised. The RSPCA were powerless to take legal action as the animals weren't covered by the Animal Welfare Act.

Until decapod crustaceans are included under the definition of 'animal' in welfare legislation, the UK government is not obliged to draw up guidelines for their humane slaughter. This means that even where restaurants and supermarkets want to do the right thing, it's not easy to find guidance. That's why we've provided some below. Why not share with your local restaurant or supermarket?

Inhumane Slaughter Methods

All of the following methods have been described as inhumane by the EU's Animal Health and Welfare Scientific (AHAW) Panel (4):

 

  • Live boiling. During this process lobsters and crabs thrash, try to escape, and shed their limbs, known to be a sign of stress. Roth and Øines  (2010:294) estimate that an edible crab boiled alive will be able to sense heat for at least three minutes. (5)

 

  • Chilling in the freezer/ice slurry before live boiling. There is no evidence to suggest that this induces anaesthesia rather than just paralysis (6). Roth and Øines find that chilling is often slow and ineffective (5) . Keeping live lobsters on ice has been banned in Switzerland and Italy.

 

  • Live carving / dismemberment. Whilst some uses of the knife may be more humane than others (see the RSPCA's guide), it is vital that the correct nerve chains are severed quickly. In particular, lobsters must be severed lengthways all the way down the body. All too often this is not the case, with chefs claiming splitting the head of a chilled lobster kills it instantly. This method is highly likely to cause pain - even if the creatures have been previously chilled to a torpor (4)

Humane Slaughter Methods

At present, there are no UK government or UK charity guidelines on the most humane method of slaughtering decapod crustaceans. They must first be recognised as sentient, pain-feeling creatures and included in the definition of 'animal' before the government will set them.

 

However, international guidelines exist and are largely in agreement. The most  comprehensive advice is provided in this guide by RSPCA Australia, who recommend electrical stunning/slaughter (using special equipment) as the quickest and most humane method.  Devices such as the Crustastun are available for restaurants and the Stansas for large-scale processors (10).

 

Alternatively, the next best method is appropriate chilling for the species (either in air or water), followed by the mechanical destruction of the brain with a sharp knife  by professionals trained in the unique biology of each species. The methods for crabs and lobsters are different.

There are many examples of good practice. Tesco's own brand UK brown crab and lobster is  stunned prior to slaughter. Waitrose stun their UK Brown Crabs and Lobsters. Some restaurants such as Locanda Locatelli and Quo Vadis have committed to using the Crustastun. But with no legal guidelines, there is no obligation for the food industry to treat crabs, lobsters and crayfish humanely, either in storage or during slaughter.

 

The government and the food industry think that the British public don't care about crustaceans.  Will you prove them wrong?
