Giant liver fluke has established permanent natural foci on two continents. North America represents the original continent of the parasite occurrence, while Europe is the continent where F. magna was introduced along with its cervid hosts. In North America, F. magna occurs in five enzootic regions across the United States and southern Canada: (1) the northern Pacific coast; (2) the Rocky Mountain trench; (3) the Great Lakes region; (4) northern Quebec and Labrador; and (5) Gulf coast, lower Mississippi, and southern Atlantic seaboard. In Europe, giant liver fluke has established three permanent natural foci: (1) La Mandria Regional Park in the northern Italy; (2) Czech Republic and southwestern Poland; and (3) Danube floodplain forests, involving Austria, Slovakia, Hungary, Croatia and Serbia. This chapter summarizes details on F. magna distribution in all North American enzootic regions and European natural foci. Besides permanent foci, sporadic findings of the parasite have been reported throughout the world. Occasional findings very probably represented only single detection of the parasite introduced to the particular region without further establishment of the permanent focus.
