Studies have found that the infection rate and degree of lung fluke - the larvae of the long-legged crab are very high.

According to experts, if crabs are eaten after being slightly heated, the infection rate of lung fluke is 20%. If they are eaten pickled crabs or drunken crabs, the infection rate of lung fluke is as high as 55%. If crabs are eaten raw, the infection rate of lung fluke is as high as 71%.
