Tangshan Market Supervision Bureau recently announced that red tides occur in coastal areas of Hebei from May to August every year. After the toxic algae in the red tide are eaten by shellfish such as Scapharca subcrenata and sea rainbow, consumers will have great risks in eating these Scapharca subcrenata sea rainbow, mainly because they are easy to be poisoned. Excessive consumption can lead to poisoning symptoms such as diarrhea, abdominal cramps, vomiting and nausea, and limb muscle paralysis, which requires immediate medical attention.

Why can't you eat clam sea rainbow in the near future? Because from May to August every year, there will be red tides along the coast of Hebei Province, which will contain a lot of toxic algae. After eating this poisonous algae, the toxin will gradually accumulate in shellfish such as wild clam and sea rainbow along the coast. If people eat too much of these poisonous clams and sea rainbow, it will lead to food poisoning, cause various poisoning symptoms and endanger their health, so it is risky to eat wild seafood and shellfish in the near future. In recent months, at the peak of red tide outbreak, consumers are prone to eating wild shellfish poisoning. It is best not to buy and catch wild shellfish. Even if you eat other shellfish and seafood, you should pay attention to removing its internal organs first, and it is not advisable to eat too much.

Wild shellfish toxins are difficult to kill. Of course, wild shellfish such as sea rainbow and clam are not toxic, but after they eat toxic algae in red tide, toxins will accumulate in their bodies, and this algae toxin is colorless and tasteless, just like the invisible poison that can kill people in martial arts novels. People are poisoned without observing any abnormal taste. Some people may think that these shellfish will be sterilized at high temperature if they are cooked more and for a long time. We can only think too much about this idea of killing shellfish at high temperature, because this toxin is extremely heat-resistant and cannot be eliminated by cooking, and the paralytic shellfish toxin contained in it is not only extremely toxic, but also has no effective detoxification method at present. Once people take too much of this toxin, they will have mild quadriplegia and numbness of their lips, and severe respiratory paralysis will be life-threatening.

What are Scapharca subcrenata and sea rainbow? Scapharca subcrenata and Haihong are both seafood shellfish living on the seashore and coast, among which Scapharca subcrenata is a medium-sized shell with a shell length of 4-5 cm and 30-34 radial ribs on the shell surface, which is one of the most commonly eaten seafood shells. Sea rainbow, also known as mussel, is a common shellfish with a dark brown shell. After cooking and processing, it can be made into dried products, called mussels. Its shell is about 6 to 8 cm long and often grows densely on rocks near the beach, so people living by the sea can easily capture them home.
