Why can't you eat snakes?

You can't eat snakes for several reasons:

1, snake meat contains a lot of parasites and germs.

Snakes feed on wild animals such as frogs and mice, and there are many parasites in their bodies. Because of its strong vitality, it is impossible to kill them all in a high-temperature heating environment. If humans eat them, parasites may parasitize the human body, absorb a lot of vitamins, compete with the host for nutrition, and cause damage to the host tissues and organs.

If it enters the human central nervous system, it will cause paroxysmal headache, epilepsy, convulsion, hemiplegia, numbness of limbs, coma, jet vomiting, blurred vision and other symptoms. In addition, sparganium is parasitic in human body, which can directly poison or damage human tissues, leading to cell degeneration and necrosis.

2, damage to the ecological environment

Snakes play a very important role in the natural ecological environment. Snakes are an important part of natural ecosystem, and they are balanced by the relationship of food chain. If it is caught and eaten in large quantities, it will cause problems in the food chain and seriously destroy the balance of the ecosystem.

From the health point of view, it is not advisable to eat snakes.

Due to living environment problems, snakes are covered with parasites. Moreover, ordinary cooking methods are not suitable for killing these parasites, and people will cause cross-infection after using them. In addition, excessive consumption of game will more easily lead to the evolution of viruses, so that diseases that humans should not have will also cause harm to the human body, such as SARS. At the same time, poisonous snakes are very toxic. If you don't pay attention to them when fishing or eating, they are easy to be poisoned and threaten people's lives.

4. Medicinal value of snakes

Snakes are of great value and should not be caught and eaten in large quantities. As early as 2000 years ago, the medical work Shennong Baicao recorded the medicinal effects of some snake products, and Compendium of Materia Medica (Li Shizhen in Ming Dynasty) recorded more than ten kinds of medicinal snakes.

The living habits of snakes

The snake is a kind of temperature-changing animal, and its body temperature changes with the temperature. It likes warmth and is afraid of cold, because the snake itself does not have a perfect thermoregulation mechanism to generate and maintain a constant body temperature. ?

The optimum temperature for snake activity is 20~30℃. In this suitable range, the growth rate of snakes increases linearly with the increase of temperature. For example, a study showed that the monthly weight gain of adult cobras was 64.7, 72.7 and 94.3 grams at 18℃, 23℃ and 28℃, respectively (the difference between young cobras was greater). But if it exceeds 35℃, it will cause anorexia and get sick, and if it exceeds 40~45℃, it will die quickly.

Air humidity also has a great influence on snakes, generally 50~70% is appropriate. Too high is easy to get mildew pneumonia, and the mortality rate in the south is high; Too low (such as the spring drought in the north) is not conducive to molting (especially pregnant snakes), affecting their continued growth and even causing death. "Snake aisle, heavy rain" is also the result of low air pressure and high humidity before the rain, and snakes feel uncomfortable running around.
