Echinococcus multilocularis

The parasite Echinocioccus multilocularis has never been found in wildlife in mainland Norway.

The aim of the programme is to document freedom of Echinococcus multilocularis in mainland Norway.

Echinococcus multilocularis is endemic in large parts of the northern hemisphere, including eastern and central parts of Europe. In 1999, E. multilocularis was detected in Denmark and on the high-arctic Norwegian islands of Svalbard and in Sweden in 2011. The spread of the parasite to new areas can occur with wild Canids (primarily red foxes and wolves in Norway) infected rodents as stowaways in cargo transports or with dogs imported from areas where the infection is established.

Anthelmintic treatment of imported dogs is compulsory to prevent introduction of the parasite through infected dogs. However, according to the EU Directive 998/2003/EC on pet movement, the maintenance of this national regulation post 2008 requires documentation of an E. multilocularis - free status within Norway.
