Angiostrongylus vasorum in red foxes

Monitoring of Angiostrongylus vasorum in Norway is financed by the Norwegian Food Safety Authority. 

The parasite A. vasorum was detected for the first time in red foxes in Norway in 2016. The surveillance program aims to document the status of the parasite in red foxes in Norway.


In 2018, A. vasorum was detected in four of 67 (6.0%) red foxes (Vulpes vulpes) examined by serological analysis. So far, the surveillance of A. vasorum in Norway has included relatively few animals, and further studies, including randomly selected animals from the whole country, are needed to determine the geographical distribution and the true prevalence of A. vasorum in wild canids.
