What is red tide?

red tide is called "harmful algal bloom" internationally. When it occurs, it often forms a large red scene on the ocean or lake, so it is likened to a "red ghost" by many people.

02

is divided into non-toxic red tide and toxic red tide

non-toxic red tide is generally harmless.

The red tide organisms in the toxic red tide can produce toxins such as paralytic shellfish poisoning, diarrhea shellfish poisoning, neurogenic shellfish poisoning, etc., once consumed by humans, it is easy to cause poisoning reactions.

is a more toxic organic toxin

Shellfish toxin can be lethal!

Paralytic shellfish toxin

is one of the most common toxins in my country's marine red tide toxins

accounts for about 87% of the poisoning incidents caused by algae toxins

According to statistics

The global annual poisoning incidents caused by the paralytic shellfish poison

is about 2000 From

mortality rate reached 15%

shellfish poisoning with these symptoms!

Once the shellfish containing paralytic shellfish poison is consumed, the toxins are quickly released in the body and cause neuromuscular paralysis. In mild cases, symptoms such as numbness and tingling of the lips and limbs, and paralysis of limbs and muscles may occur in the body. In severe cases, it may cause breathing.
