Over the past 10 days, new cases of African swine fever (ASF) in domestic pigs have been recorded by the veterinary authorities of four European nations.

Only Romania has confirmed an outbreak on a commercial farm. Affected was a premises in the central region of Timis, starting on October 9. According to the official notification to the World Organisation for Animal Health (WOAH), more than 400 of the 39,191 animals at the farm died.

Furthermore, three other outbreaks in Romanian swine were confirmed in Romania this month. These occurred in backyard herds, each with between three and seven pigs.

Since October 2019, Romania has been battling ASF in an ongoing disease outbreak series. Affected have been mainly domestic pigs in backyard herds and wild boar across the south, southeast and central counties of the country.

In the southeast European state of North Macedonia, ASF virus has been detected in four more herds of domestic pigs. Herd sizes ranged from five to 67 animals.

Of the latest outbreaks, three were in municipalities in the Northeastern region, and bordering Serbia. As for the nation’s 26 previously reported outbreaks, the other recently affected premises was in the Eastern region.

In early July, presence of the ASF virus was confirmed after 13 pigs died at a farm in the Emsland district. The remaining 1,817 animals at the premises were culled, and no further cases in the state have since been detected. It remains unclear how the infection was transmitted to the farm. This was the latest of seven confirmed ASF outbreaks in domestic pigs in Germany over the past two years.
