For the first time, African Swine Fever has also hopped onto a large domestic pig farm in Western Poland, affecting over 23,700 pigs. It is the largest affected pig farm since Poland has started reporting ASF outbreaks in 2014.


The outbreak was discovered on March 18 and the confirmation was given on Saturday, March 21, according to the German agricultural titleTop Agrar. The report has already been filed in the European Animal Disease Notification System (ADNS).


8,000 sows on the farm


The farm is located near the village of Niedoradz, Lubusz province, at 66km as the crow flies from the border with Germany. According to Top Agrar, there were about 8,000 sows on-site and roughly 135 pigs had died of the virus. Obviously, the authorities moved to cull the entire farm’s pig population and protection zones have been created around the farm.


It is not a surprise that the first affected pig farm is around Niedoradz. In recent weeks, more than once, dead wild boar had been found in the vicinity of the village’s pig farm houses.


ASF in 5 provinces in Eastern Poland


The virus has been circulating in 5 provinces in Eastern Poland since 2014. In those areas new outbreaks continue to be found as well. So far, in Eastern Poland, 237 (backyard) farms were known to have been infected. The largest affected farm in Eastern Poland had 9,400 animals on-site.


In Western Poland – an entirely different area of Poland, as can be seen on the map, the virus has been in the wild boar population since November 2019. Ever since the virus was confirmed in wild boar carcasses on 502 locations. The outbreak zone stretches out into 3 provinces, being Lubusz (413 outbreak locations), Greater Poland (84) and Lower Silesia (5). The carcass found closest to Germany was found mid-January 2020, at a distance of 13km from the German border.


In total, in March ASF-infected carcasses have now been found on 143 locations in Western Poland, exactly as many as in the whole month of February.


It is difficult to gauge at this time how many wild boar have died because of ASF in Western Poland, because one finding place can relate to 1 affected carcass as well as 10 simultaneously. This type of information will only be shared later by the authorities.
