The number of Belgian wild pig carcasses found to be infected with African Swine Fever is now up to 32, reports René Collin, Wallon Minister of Agriculture.
Since the first case was reported on Sept. 13, Belgium has implemented numerous measures to contain the ASF outbreak in the region of Etalle, isolating a 240-sq.-mile zone, reports Swine Health Information Center (SHIC). More than 60 commercial pig farms have been screened, and only negative results were reported.
However, new cases in wild boars were identified. A total of 4,150 pigs will be culled on 58 farms, SHIC reported in their Oct. 1 update.
In total, government officials have collected 96 wild hog carcasses, including 70 in the perimeter where the previous infected boars had been found. Of the 70 carcasses, 32 were viropositive cases. Of the collections outside of the perimeter, only one tested positive for the virus.
“This is good news, as it shows that the virus hasn’t spread,” said Pierre Wiliquet, spokesperson for Minister Collin, to the Brussels Times.
How the virus arrived is still a mystery. Researchers hope genetic analysis of the infected animals will help narrow the possible route of transmission.
