Scientists have found that it can take lobsters between 35 – 45 seconds to die when plunged into a pot of boiling water — and if they are dismembered their nervous system can still function for up to an hour.
Contrary to claims made by seafood sellers, lobsters do feel pain, and they suffer immensely when they are cut, broiled, or boiled alive. Most scientists agree that a lobster's nervous system is quite sophisticated.
“Nope! A sound can emit from the shells of the lobsters — a high-pitched sound — but it's due to steam escaping through a fissure in the shell, not the lobsters 'screaming,'” she explained. This doesn't necessarily mean the cooking process is pain-free for the lobster.
What about Australia? Switzerland is not the first place to ban boiling live lobsters; it's already illegal in New Zealand and in the Italian city of Reggio Emilia. In several Australian states, including New South Wales, fish and crustaceans are included in animal cruelty laws.
Switzerland is not the first to ban the practice. In fact, boiling lobsters alive has been outlawed in the United States since at least 1999.
Head First into Boiling Water
Hold the lobster around the middle to avoid those claws and put it head first into the water. It will die quickly. Boiling water is also the best way to cook the lobster so you can leave it in there and carry on the cooking process.
Why Do People Cook Lobsters Alive? Boiling lobsters alive is a way to reduce the risk of food poisoning from bacteria that live in their flesh and that quickly multiply on their carcasses, according to Science Focus.
A lobster can live out of the water for a couple of days if kept in a moist and cool place. How can a lobster live so long out of water? A lobster can extract the oxygen from the air, but in order to do this its gills must be kept moist or they will collapse.
Freeze the lobster for 30 to 60 minutes, then put it in the pot of boiling water head-first. While the boiling water, rather than the freezer, will kill it almost instantly, the cold will immobilize the lobster so it won't thrash about.
Do Lobsters Feel Pain When Cut In Half? Again, all the evidence shows that they do. And considering their nervous systems cannot go into shock, they are likely to feel this pain for up to an hour after being cut in half.
Because lobster, like most shellfish, begins excreting some dangerous and nasty chemicals as soon as they die. Cooking them live stops this process before it can start. If they are cooked after death, these chemicals, in large enough amounts, can lead to amnesic shell fish poisoning.
Freezing Live Lobsters: Just Don't Do It
Safety aside, freezing and thawing lobster prior to cooking it will lead to enzymes leaching into the meat, resulting in a mushy, unappetizing texture.
To make sure, pick up the lobster - if the tail curls under the body, it's alive. This test is especially important with lobsters that have been stored on ice because they're so sluggish, it's sometimes hard to see movement.
Researcher Michael Kuba says that lobsters are “quite amazingly smart animals.” Like dolphins and many other animals, lobsters use complicated signals to explore their surroundings and establish social relationships.
It's not necessary, but if you'd like to kill the lobster before cooking it, do so by driving a knife into the center of its head and pushing down to split it open.
Many people have heard that boiling crustaceans alive is a painful and inhumane way to kill a crab or lobster and this is backed up by many convincing studies as well as physical evidence such as animals dropping their limbs and writhing around before dying.
The LSE team reviewed more than 300 scientific studies on the topic and came to a firm conclusion: There is solid evidence that mollusks and crustaceans are sentient.
Plunging them into boiling water, freezing them or 'drowning' them in fresh water are not humane.
From an animal welfare perspective, Tensen says electrical stunning followed by a swift and precise chop through the lobster's 13 nerve centres (spanning the central length of its body, from the tail to between the eyes) is the way to go. The electrical shock stops all neural activity within half a second.
Stunning the crustacean by chilling it in cold air or an ice slurry - saltwater or freshwater, according to the species - for at least 20 minutes. Once the lobster is stunned, it should be mechanically killed as quickly as possible, says the RSPCA, by splitting it along the longitudinal midline on its underside.
Most lobsters that you see in a grocery store or at a restaurant are at least 5-7 years old and weigh about 1-2 pounds. But lobsters can be much bigger and much older. They could live to be over 100 years old!
BOSTON Call it cryonics for crustaceans. A Connecticut company says its fro zen lobsters sometimes come back to life when thawed. began freezing lobsters with a technique it used for years on salmon after an offhand suggestion by some workers. It found that some lobsters revived after their subzero sojourns.
After letting them freeze, the lobsters were then thawed in 28-degree sea water. The result was that only two came back to life out of thirty lobsters. Isn't that surprising?
