The main cause of poisoning is the tetrodotoxin it contains, which can produce symptoms of poisoning such as dizziness, vomiting, numbness of the lips and fingers after consumption, with an incubation period of as little as 5 minutes and a maximum of 4 hours.

For snail poisoning, there is no specific antidote to the poison. The Ministry of Health issued an announcement stating that no food production and business operation unit shall purchase, process and sell sea snails.

You go and put it in the water, and after a minute, you pick it up and gently attach the fishbell-like thing on the screw, and if it is taken back, it is alive, and if it doesn't move, it is dead.

To determine whether the snail is or is dead, you can press the cover at the snail mouth, and if you press it, it can bounce up as a live snail, and if you can't play it, it will be a dead snail. The dead snail meat will turn into water, so it will be very light, soak the snail in the water, the live snail will expose its body in the water for a while, and the skin will quickly retract when it touches it, and if it floats up, it proves that the burning high pants are obviously a dead snail. Snails that have been dead for a while have a more obvious fishy smell.

Here's how to judge:

1. Smell. If the screws in the bag smell bad, then many of the screws inside must be dead. Of course, there are survivors among them.

2. Viewing the shape. Dead screws are generally deeply recessed with the cover of the screw not.

3. Look at the whole. If the whole bag of screws is left to stand for 2 minutes, some of the screws on it will quietly open the cover, indicating that the overall survival condition is good.

There are two kinds of snails, one is the common name of the snail genus, the scientific name is margarya, which is endemic to China and is only distributed in Yunnan. The second is the common name of the square ring snail (scientific name bellamya quadrata), which is the favorite food of Zhejiang people, also known as: square snail.

The "dead or alive" of a screw generally refers to whether the thread has been damaged or worn, making it impossible to continue to use or disassemble. Here are a few ways to tell if a screw is "dead or alive":

Try to turn the screw with an appropriate wrench, if it feels loose, it means that the screw has not been damaged; If you feel that it is difficult or impossible to turn, it is likely that the thread is damaged or tightened.

Observe whether there is obvious deformation or peeling phenomenon of the screw head or thread taulow, if there is, it means that the screw has been subjected to excessive force or has been used for a long time.

Use a special measuring tool, such as a thread gauge or mirror, to observe the condition of the thread to determine if it has been deformed, worn or damaged.

In conclusion, attention and the right tools are required when using screws to avoid damage to the screws in order to better maintain the normal operation of equipment and machinery.

1. Smell. If the whole bag of screws collapses and makes a foul smell, then surely many of the screws inside are dead. Of course, there are survivors among them.

2. Viewing the shape. Dead screws are generally deeply recessed with the cover of the screw not.

3. Look at the whole. If the whole bag of screws is left to stand for 2 minutes, some of the screws on the top of the branch rock will be quietly opened, indicating that the overall survival condition is good.

4. Screws and other soft shellfish are very vigorous. If the screws are not cleaned of the mud outside the shell, they can survive for more than a week when they are put into a woven bag. (The mud on the outside of the snail shell has a moisturizing effect, which is very important for the survival of the screw).

1. For the kind of conch whose tentacles or snail flesh is exposed, it can be automatically retracted by gently touching it with your hand, which means that it is a live conch.

2. For the conch shrunk in the shell, you have to smell the smell with your nose, if there is no peculiar smell, it is a live conch or a conch that has just died, and the conch that has just died can also be eaten.

2. Sea screws, also known as wheat snails or sea lion snails, grow in the coastal areas of Zhejiang Province, Fujian Province and Guangdong. The smallest sea screw is 1 cm, and the largest can be up to 10 cm. The snail meat is delicate and crispy, fresh and sweet, and can be eaten.

Fleshiness: The flesh of a live sea conch is plump and elastic, while a dead sea conch is relatively shriveled due to constant water loss during storage. Color:

Live conch is whiter in color, while dead sea conch is darker in color. Taste: Live conch is delicious and has a milder fishy smell, whereas dead sea conch has a strong fishy smell.

Shell: Knock on the shell of a conch, the live conch will close the shell due to tension, and the dead conch will not move. <

1. Meat quality: The flesh of the live sea conch is full and elastic, while the dead sea conch will constantly lose water during storage and be relatively shriveled.

2. Color: The color of the live conch is more white, and the color of the dead conch is relatively dull.

3. Taste: The live conch is delicious and has a light fishy smell, while the dead conch has a strong fishy smell.

4. Shell: Knock on the shell of the conch, the live conch will close the shell due to tension, and the dead conch will not move.

To determine whether a conch is alive or not, you can use the following methods: look at it directly, the flesh of a live conch will continue to bubble out, or gently touch the flesh of a conch with your fingers, and the meat will shrink, indicating that it is alive. You can also smell the smell, the live Songyu seafood only has a fresh smell, and the dead conch strip has a fishy smell.
