Echinococcus in red foxes

The zoonotic dwarf fox tapeworm Echinococcus multilocularis has never been detected in mainland Norway.

The objective of the surveillance program is to document freedom of E. multilocularis (i.e. a prevalence below 1% at a confidence level of at least 95%) in mainland Norway.


The prevalence of Echinococcus multilocularis was based on PCR analysis of faecal samples from 536 red foxes (Vulpes vulpes) and 34 grey wolves (Canis lupus) collected during the licensed fox-hunting season in 2018. None of the samples tested positive for E. multilocularis by which we deduce that the prevalence in carnivore hosts (foxes and wolves) were below 1% with at a confidence level of at least 95%.
