African swine fever virus has been detected at a large farm in Russia, as well as in two European backyard pig herds.
Over the past week, two European countries have registered new cases of African swine fever (ASF) among domestic pigs.
Most significant is an outbreak on a large farm in the Volga federal district of Russia. Of the almost 39,000 pigs present there, 31 died, according to the official report to the World Organisation for Animal Health (OIE). The fate of the rest of the herd in Samara oblast is not recorded by the agriculture ministry. In the Central federal district, ASF was also detected in the only pig at a holding in Voronezh oblast.
Since the start of the year, ASF outbreaks have been confirmed at multiple locations in these areas, as well as in the Southern federal districts.
ASF virus detected in another Polish backyard herd
Just one outbreak of ASF has been reported by the Polish chief veterinary office over the past week. Affected was a herd of 19 pigs in the Subcarpathian province (Podkarpackie).
This latest outbreak brings the country’s total outbreaks in domestic pigs since March to 102. The number of pigs directly impacted now stands at 56,990.

Up to October 25, there have been 1,020 ASF outbreaks among domestic pigs in Europe since the start of 2020, according to the Animal Disease Notification System of the European Commission (EC). This system covers European Union member states and several surrounding countries, but not Russia.
