Finland expanded its restricted zone for African swine fever (ASF) on Friday after the virus was detected in a wild boar roughly 40 kilometers west of previous boundaries, according to the Finnish Food Authority. The finding of an adult wild boar carcass in a field in Pyhtaa marks a significant westward shift for the disease, which had previously been confined entirely to Virolahti near the Russian border since the country’s first detection in late July.
Finland Widens African Swine Fever Restricted Zone Westward
The newly expanded infected zone now encompasses Kotka, Hamina, and Pyhtaa, alongside parts of Loviisa, Lapinjarvi, and Kouvola in the southern and southeastern regions, as reported by the Finnish Food Authority. Officials noted that the stricter core zone surrounding Virolahti remains untouched for now. Current emergency measures ban hunting and the feeding of wild animals across all restricted areas. Strict controls also govern pigs, wild boars, and any meat or reproductive material derived from them.
Broader movement restrictions in forests that apply within parts of the older infected zone have not yet rolled out to the newly added municipalities. According to the Food Authority, regulators will weigh additional restrictions next week. Testing data shows the virus has now been confirmed in 36 wild boars since the initial July discovery in Virolahti.
Economic Impacts on Finnish Pork Exports
The outbreak has disrupted trade channels for the domestic pork sector. While European Union member states continue receiving normal shipments from areas outside the restricted zone, access to certain markets outside the trade bloc faces disruption, according to Finnish public broadcaster Yle, citing the Finnish Food Industries Federation. Data from the federation shows Finland exported approximately 74 million euros worth of pork in 2025, with roughly 77 percent of those products heading to destinations outside the EU.
Did you know? African swine fever does not infect humans, but the highly contagious viral disease causes severe illness and death in domestic pigs and wild boars, prompting strict biosecurity rules across Europe.
Regional Spread and Strict Biosecurity Measures
The virus is spreading at an alarming rate in areas near Finland, particularly in Estonia where the disease has reappeared in domestic pigs, according to the Finnish Food Authority website. Since 2014, ASF has circulated among wild boars and domestic pigs across Estonia and other Baltic countries. During the summer, numerous cases emerged in Estonia, Lithuania, and Poland. In Estonia alone, the virus hit five pig farms—four of them very large operations—requiring the culling of over 17,000 pigs to contain the spread.
To shield domestic herds, the Finnish Food Authority urges travelers not to bring pork or wild boar meat products from abroad, as these items can carry the virus. Officials also advise disposing of leftover food scraps safely, avoiding contact with foreign wild animals, and thoroughly washing and disinfecting footwear and outerwear following hunting trips abroad. Farm owners must restrict access to authorized personnel only, disinfect incoming vehicles, and keep equipment farm-specific while utilizing fences and electric barriers to block wild boars.
Frequently Asked Questions
Can humans contract African swine fever from infected animals?
No. According to the Finnish Food Authority, African swine fever is not transmissible to humans, though it causes fatal illness in pigs and wild boars.
How many wild boars have tested positive in Finland so far?
The Finnish Food Authority confirmed that the virus has been detected in 36 wild boars since the first outbreak was discovered in late July.
What are the rules for pork exports from Finland?
Exports to European Union states continue normally from regions outside the restricted zone, but the outbreak has disrupted access to certain markets outside the trade bloc.
How can pig farmers protect their herds from ASF?
Farmers must enforce strict biosecurity, restrict farm access, disinfect incoming vehicles, use farm-specific equipment, and install fences or electric barriers to keep wild boars away from production areas.
