<unk>  are zoonotic infections caused by trematodes. In foodborne<unk> , these parasites are transferred from animals to humans. Transmission of<unk>  can occur through the consumption of water and food that is contaminated with trematodes in the larval stages of their life cycle. In a host organism, eggs of trematodes can spread through faeces, and sputum if the host is infected by a lung fluke. Once these reach water, they infect aquatic snails which act as intermediate hosts for<unk>  that is transmitted through food. A second host will depend on the species of trematode, and are usually aquatic animals Some<unk>  such as Schistosomiasis can also be transmitted when skin comes in contact with water containing the parasite. Trematodes all have different life cycles in which they can reproduce asexually and sexually. When trematodes are at the metacercariae stage in their life cycle, humans and other definitive hosts such as mammals and birds can be infected. In humans, adult trematodes can survive for 25 years. Fasciola hepatica, a species of trematode that causes<unk> , and infects the liver Types of<unk>  There are different types of<unk>  depending on the species of trematode that has infected the organism as well as their location in humans. There are over 80 different species of trematodes that are transmitted through food that can cause infections in humans. Foodborne<unk>  include intestinal flukes, lung flukes and liver flukes. Liver flukes cause liver disease in humans and are caused by the species Clonorchis, Opisthorchis and Fasciola. Intestinal flukes infect the gastrointestinal tract and can be caused by the species F. buski, Echinostoma, Metagonimus, Heterophyes, Gastrodiscoides. Lung flukes, mainly the genus, Paragonimus, infect the lungs of organisms, causing infections that can last for up to 20 years in humans. Foodborne<unk>  include Clonorchiasis, Opisthorchiasis, Fascioliasis and Paragonimiasis.
