ASF in Finland 2026

African swine fever cases in Finland

The first finding of the virus causing African swine fever (ASF) was made in Finland on 30 July 2026. The genome of the virus was detected by PCR testing in wild boars found dead in Virolahti. The result was verified in the EU’s reference laboratory for ASF. African swine fever (ASF) is a serious viral disease of pigs and other suids. The disease is not transmissible to humans.

Infected zone

Following the confirmation of African swine fever (ASF) in a wild boar, the Finnish Food Authority established an infected zone around the outbreak location and, within it, a core area subject to stricter restrictions than those applying elsewhere in the infected zone. When determining the boundaries of the infected zone, consideration is given to available information on the distribution of the disease, the local wild boar population, and the main natural and man-made barriers that restrict wild boar movements.

The restrictions and conditions applicable within the infected zone and the core area are intended to prevent the spread of ASF. This includes, for example, restricting activities in the field that could disturb wild boars and cause them to move outside the infected zone, or that could facilitate the spread of infection beyond the infected zone through people, vehicles, or equipment. Disease control measures directed by the Finnish Food Authority are implemented within the infected zone and the core area with the aim of eradicating the disease, including the safe disposal of wild boar carcasses infected with ASF and the controlled reduction of the wild boar population.

To prevent the spread of the disease, an infected zone was established in the area on 30 July 2026. The decision establishing the infected zone was refined by a decision issued on 28 August 2026, and a core area was established within the infected zone, where stricter restrictions apply than in the rest of the zone. The infected zone was extended by a decision issued on 28 August 2026.

The restrictions currently in force in the area are set out in
