Trematodes are flat helminths, commonly referred to as flukes in the medical field, with the majority living in vertebrates and a small portion in invertebrates. They are parasites that can settle in the human liver, bile ducts, lungs, and intestines, causing certain reactions and diseases in these areas. Among these, some species in the Opisthorchiidae and Fasciolidae families are liver flukes and pose a threat to public health.  Fasciola hepatica and Fasciola gigantica, large liver flukes belonging to the Fasciolidae family, and Dicrocoelium dentriticum, belonging to the Dicrocoelidae family, are called small liver flukes and are mostly transmitted to humans through the consumption of metacercerial aquatic plants. Clonorchis sinensis, Opisthorchis viverrini, and Opisthorchis felineus, belonging to the Opisthorchiidae family, are also small liver flukes, and transmission to humans can occur as a result of consuming raw or undercooked fish. This review addresses the importance of foodborne trematodes from both a medical and public health perspective.
