Giant Liver Flukes
Prevention or control of Giant Liver fluke in wild cervids is not practical or likely needed. The Idaho Department of Fish and Game prohibits the importation of white-tailed deer and elk partially due to the presence of this fluke in other parts of North America. Several domestic Cervidae farms in Idaho have brought elk into Idaho from affected areas and introduced this parasite to local areas in Idaho. There is a significant risk of continued introductions of this parasite with with importation of domestic Cervidae from infected areas, inadequate treatment prior to importation, or lack of environmental treatment of affected premises in Idaho.
