In Italy, the African swine fever virus has been detected in wild boar in a second province in the Lazio region, while further cases are confirmed in previously affected areas.
As the number of African swine fever (ASF)-infected wild boar in Italy passes 150 and the disease is detected in a fourth province, authorities are further stepping up control measures.
According to official reports, the country’s first cases of ASF on the mainland were confirmed in early January in the northwestern region of Piedmont (Piemonte). Soon afterwards, wild boar in Genova province in neighboring Liguria tested positive for the virus. One month ago, first cases were identified in a natural park in the Rome area, also in wild boar.
Last week, authorities in the Piedmont region were reported to be establishing nets to control the movement of wild boar. According to ANSA, the nets are in the province of Alessandria, where this region’s cases have so far been detected. Gradually, the barrier will be moved so that it connects with a similar structure in Genova (Genoa), the affected province in the Liguria region.
In Piedmont, authorization has been granted for the depopulation of wild boar.
At the end of May, there were demonstrations in the Italian capital, Rome, reported ANSA. Pig farmers and other people from all over the country called for urgent action to reduce the wild boar population. According to a recent survey, almost 70% of the population want the national population of 2.3 million wild boar to be reduced. Among the reasons given are that the animals are dangerous, a nuisance, and cause damage to crops and the environment.
Latest official figures put the number of confirmed ASF cases in Italy at 157. This is according to notifications to the World Organisation for Animal Health (WOAH).
The total comprises 137 in the northwestern regions of Piedmont and Liguria, and 20 in Lazio. In the latter region, the first case outside the Metropolitan City of Rome Capital area was detected at the end of May. The animal was in the neighboring province of Rieti.
