Lobsters and other shellfish have harmful bacteria naturally present in their flesh. Once the lobster is dead, these bacteria can rapidly multiply and release toxins that may not be destroyed by cooking. You therefore minimise the chance of food poisoning by cooking the lobster alive.
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.
Fresh live lobsters can stay in your refrigerator one to two days. Keep them in the back, where the refrigerator is coldest. They must be kept alive until you cook them. Do not store live lobsters in any kind of water—it will kill them.
We believe that electrical stunning before killing of lobsters is the most humane and effective method as it renders them immediately insensible before death which then occurs within seconds. Plunging them into boiling water, freezing them or 'drowning' them in fresh water are not humane.
Whether it is believed the lobsters experience pain or not, killing the lobster just before cooking is the preferred method. Perhaps this is for the benefit of the cook as a way to minimize trauma since most people are disconnected from the killing of animals they eat.

In 1900 the US passed the Lacey Act. It was a law meant to protect plants and wildlife, which it did. But it also eventually made it a federal crime to boil a live lobster.
"If an animal feels pain, you can't just chuck it into a pot of boiling water." Boiling, microwaving, thrashing, drowning and dismembering live crustaceans has been illegal in NSW since 1997.
Lobsters Can't Go Into Shock
When thrown into a pot of boiling water it can take up to 35-45 seconds for them to die and when dismembered, their nervous systems can stay active for up to an hour. Without shock, these experiences must be excruciatingly painful.
Lobsters don't have vocal cords, and even if in agony, they cannot vocalise. The high pitched sound made by an overheating lobster is caused by expanding air rushing out of small holes in lobsters' bodies, like a whistle being blown. A dead lobster will “scream” just as loudly as if it was living.
In reality, freezing and thawing live lobsters may be safe, but it simply isn't worth the risk of toxins developing as a result of the process. Safety aside, freezing and thawing lobster prior to cooking it will lead to enzymes leaching into the meat, resulting in a mushy, unappetizing texture.
It minimizes the risk of food poisoning
So, to minimize the risk of food poisoning, crustaceans are often cooked alive. That said, many consider the practice to be unethical as crustaceans are living things and consequently, can feel pain.
How long can a lobster live out of water? A lobster can live out of the water for a couple of days if kept in a moist and cool place.
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. Plus they have been deemed tastier and better presented on the plate when cooked this way.
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.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
“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.
Not you—the lobster you're hoping to eat. Putting cold-blooded animals like crustaceans (or insects) into a freezer or in icy water numbs them, and they don't seem to have pain receptors that react to cold (they do live at the bottom of the ocean, after all).
A lobster does not have a complex circulatory system like we do. Instead of a four-chambered heart it has a single-chambered sac that consists of muscles and several openings called ostia. Their heart lies above the stomach on the upper surface of the animal (but still below the carapace of course!)
They occur in hot waters in the Pacific, Atlantic and Indian oceans and also in Red and Mediterranean seas. In Australia the Southern Rock lobster, caught in south-eastern Australia, and the Western Rock lobster, found in southern Western Australia, are two species of particular commercial value.
They found that, on average, male European lobsters live to 31 years old, and females to 54. There were a few exceptions: one female had reached 72 years old. Lobsters certainly do not live forever.
A temperate species, western rock lobsters are only found on the continental shelf off the coast of Western Australia, with most living in the area between Perth and Geraldton.
In most countries, they are excluded from the scope of animal welfare legislation, so nothing you do to them is illegal. The result is that they are treated in ways that would clearly be cruel if inflicted on a vertebrate.
Jaren G. Horsley PhD. 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.
So why do these crustraceans turn red when they're cooked? Lobsters and crabs have a pigment called astaxanthin in their shells, which has the ability to absorb blue light, making the shell appear red under certain conditions.
