Wild boar health surveillance

The Norwegian Veterinary Institute (NVI) is collaborating with the Norwegian Food Safety Authority (NFSA) on a surveillance programme for wild boar in Norway with the aim of monitoring the incidence og infectious agents that are transmittable between wild boar, to domestic pigs and to humans.

If you would like to receive sample collection equipment in order to submit samples from wild boar hunted in Norway, please contact your local office of the NFSA or the swine health expert at the NVI Carl Andreas Grøntvedt. 

2025

In 2025, the Norwegian Veterinary Institute received samples from 499 wild boars, slightly exceeding the 491 harvested wild boars reported to the Norwegian Cervid Register. In addition, samples from two wild boars found dead were examined as part of passive surveillance for African swine fever (ASF) and classical swine fever (CSF), with no disease agents detected.

All samples tested negative for antibodies against Aujeszky’s disease virus (ADV), transmissible gastroenteritis virus (TGEV), porcine reproductive and respiratory syndrome virus (PRRSV), porcine epidemic diarrhoea virus (PEDV) and swine influenza virus (SIV). Antibodies against Mycoplasma hyopneumoniae were also not detected, except in one adult female wild boar that tested positive.

Salmonella was detected in 30 hunted wild boars, predominantly Salmonella Typhimurium (21 cases), along with several other serotypes. Parasitological examinations found no evidence of Trichinella larvae.
