Total outbreaks among wild boar in Europe this year will soon exceed the number reported for all of 2019.
For Ukraine, confirmation of an African swine fever (ASF) outbreak at a farm in Sumy represents the return of the disease to the region.
Latest to be affected was a herd of 23 pigs, one of which died, according to the official report to the World Organisation for Animal Health (OIE). Ukraine’s animal health agency reports that the last cases of ASF in this area were in June 2019. Source of the latest infection is unknown.
Bordering Russia, Sumy is in the northeast of Ukraine.
This is the second notification of the return of ASF in Ukraine in as many weeks. After a brief absence, the infection returned to the southern oblast of Zaporizhia on May 20.
New cases in Romania, Russia
Continuing a recent pattern, the majority of the 11 outbreaks reported by Romania to the OIE over the past week were in backyard herds. However, at 2,330, total losses of pigs were increased by two farm outbreaks. With around 900 and 1,386 pigs, these commercial premises were located in the south of the country in counties bordering Bulgaria and Serbia.
The latest outbreak in Russia affected a backyard herd of 20 pigs in Smolensk oblast this month. One animal died, according to the agriculture ministry report to the OIE, and the rest of the herd was culled.
Smolensk oblast is in the Central Federal District. The most recent outbreak in this series had been in a wild boar in the Republic of Adygea at the end of April.
Up to May 24, the European Commission (EC) had registered a total of 286 ASF outbreaks in domestic pigs in Europe so far this year through its Animal Disease Notification System (ADNS).
This represents an increase of 12 from the previous week’s report. Romania accounted for 11 of the latest outbreaks, and there was one new outbreak in Ukraine.
From this source, by far worst affected country in Europe so far this year has been Romania (258 outbreaks), followed by Bulgaria with 17. Also reporting cases in 2020 were Ukraine (6 outbreaks), Poland (2), and Greece, Lithuania and Moldova, each with one outbreak.

With a total of 540, Poland has reported the most new cases of ASF in wild boar to the OIE over the past week. All of the animals were found dead or culled up to the end of January of this year. The majority of cases — 316 — were from the eastern provinces of Lublin, Masovia, Podkarpackie, Podlaskie and Warmia-Masuria.
