According to the WeChat WeChat official account news of Tangshan Municipal Market Supervision Administration, Tangshan Municipal Market Supervision Administration issued the "Safety Warning on Careful Consumption of Shellfish such as Scapharca subcrenata and Haihong" on May 15, saying that red tides may occur in the coastal areas of Hebei Province from May to August every year, and shellfish may accumulate toxicity due to poisonous algae in the red tides, and poisoning incidents occur from time to time after consumers eat them. In order to avoid the recurrence of this kind of situation and ensure the food safety of the people, consumers are reminded of the following risks of eating shellfish.

According to the different symptoms of shellfish poisoning, Scapharca subcrenata can be divided into four types, namely diarrheal shellfish poisoning (DSP), paralytic shellfish poisoning (PSP), neurotic shellfish poisoning (NSP) and amnesia shellfish poisoning (ASP). At present, there is no specific medicine for all shellfish poisoning. After eating shellfish poisoning, the patient's initial symptoms are numbness of lips, hands and feet, and later symptoms such as nausea, vomiting and dizziness appear. Severe patients have difficulty breathing, limb weakness and coma.

In order to ensure people's food safety and prevent food poisoning caused by eating shellfish such as Scapharca subcrenata and Haihong, Tangshan Municipal Market Supervision Administration issued a safety warning for eating shellfish such as Scapharca subcrenata and Haihong: it is suggested that people should not collect and buy wild shellfish during the peak of red tide toxin outbreak, and when eating other shellfish seafood, they must remove their internal organs and eat too much at one time. Once eating shellfish such as Scapharca subcrenata and Haihong has symptoms such as nausea, vomiting, diarrhea, abdominal cramps and quadriplegia, you must immediately rush to the hospital for treatment.

Causes of shellfish poisoning

Shellfish such as sea rainbow clam and sea rainbow are not toxic in themselves, and toxins in the body are generally formed by ingesting toxic unicellular algae and enriching them in the body. These toxins are colorless, odorless and extremely heat-resistant, and people will be poisoned once they eat mussels containing toxins.

Paralytic shellfish toxin is one of the most common toxins in marine red tide toxins in China, which is extremely toxic. At present, there is no specific detoxification method. Once people eat shellfish containing this toxin, it will cause neuromuscular paralysis, which is manifested as numbness and tingling of mouth and lips, muscle paralysis of limbs and even respiratory muscle paralysis and death.

Tangshan State Market Supervision Bureau: Red tides may occur in coastal areas from May to August, so be careful to eat Scapharca subcrenata.
