Don't confuse this. Many places think that the blood clam is a China Rana, but it's totally different!
Like all filter-feeding animals, the living environment of blood clam (Scapharca subcrenata) contains a large number of microorganisms, so blood clam (Scapharca subcrenata) without strict sterilization and disinfection is very dangerous, especially if it is heated for only a few seconds to more than ten seconds, it will not kill bacteria. 1988 The outbreak of hepatitis A in Shanghai was caused by eating a half-life blood clam (Scapharca subcrenata). Therefore, for the sake of freshness, it is highly recommended to eat half-baked blood clams. Blood clams (clams) need to be absolutely cooked before eating! ! !
