nmark is erecting a boarder fence with its neighbor, Germany, to keep wild boar and the threat of African swine fever out. Construction began on Monday for a 50 mile long barrier. The steel fence will be a whopping 5 feet high and will extend 20 inches underground.
Swine fever is harmless to humans and all animals, except for wild boars and pigs. But there's no vaccination or treatments currently for the highly contagious virus. And that's a big problem for Denmark, whose pork industry exports add up to around $4.5 billion a year. Exports to non-EU countries would be forced to shut down if the disease took hold.
The Danes are not the only Europeans putting precautions in place. Poland enforced a mass wild boar cull at the weekend, despite protests from hunters that the measure was excessive. France has been on high alert since the virus was confirmed in September among wild boar in neighboring Belgium, which itself suffered a major outbreak last year.
Soldiers could be drafted in to help hunters cull any suspect boar.
