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.
The pathogenic cardio-pulmonary nematode Angiostrongylus vasorum (A. vasorum) was detected in eight of 300 (3%; 1.3 - 5.4%, 95% confidence intervals) red foxes (Vulpes vulpes) examined by serological analysis during the hunting season in 2019. During three year surveillance (2016, 2018 and 2019), a total of 501 samples have been examined, detecting 14 positive samples.
