Metagonimus yokogawai is aparasite belongingto the flukes . It belongs to the subfamily Heterophyidae .

In the adult stage, this small intestinal leech has a pear-shaped body with a size of up to 2.5 × 0.75 mm. The eggs are on the order of 27 × 16 μm. The larvae hatch from the egg in the water and develop as intermediate hosts in water snail species. The cercaria can then get into carp-like fish. If these are then not sufficiently cooked, they end up in the small intestine of humans or fish-eating mammals.

The disease is often asymptomatic; with massive infestation there is abdominal pain up to diarrhea. Evidence is provided in the stool. The eggs are similar to those of the Chinese liver fluke or those of the cat liver fluke . Praziquantel is used for treatment after tetrachlorethylene had also been used in the past .

The main distribution area is the Asian region with China, Japan, Korea, the Philippines, but also the Balkan Peninsula.
