Fascioloides magna resides in the liver of their definitive host Odocoileus virginianus, which is the white-tailed deer. These deer are commonly found in North America, particularly southeastern United States, therefore, so are these liver flukes. There have been other reports where they have found this parasite fairly prominent in deer in the Pacific northwest, New York, the Great Lakes states such as the Upper Peninsula of Michigan, and southern Canada. Fascioloides magna is also indigenous in livestock and other deer from the Cervidae family living in Europe. Therefore, they primarily occupy only these two continents, but Fascioloides magna has been seen sporadically in various parts of the world, which is due to the introduction of foreign species and the shipment of infected livestock.
