Poland recorded 55 outbreaks of African swine fever (ASF) in wild boars in December, the World Organisation for Animal Health (OIE) said. The disease was found only 30 kilometres from Germany, one of Europe's major pork exporters.

Asian countries including China regularly impose import bans on pork from regions where the disease has been discovered, causing huge loss of business for meat exporters. Wild boars are spreading ASF and there are fears infected animals could bring the disease into Germany, threatening Germany's huge pork exports to China.

Germany's agriculture minister Julia Kloeckner and Polish agriculture minister Jan Krzysztof Ardanowski met in Berlin and agreed new measures to jointly contain the ASF outbreak in Poland and prevent it spreading to Germany, the German agriculture ministry said.

"Discussions include setting up a fenced corridor along the border to prevent infected wild boar moving into Germany," the ministry said.

The two countries will discuss whether Germany's civil defence force should help setting up fencing.

German regional state governments in Brandenburg and Saxony have already started building fences along the Polish border in an attempt to stop infected wild boar roaming into Germany.

The two ministers also agreed to prepare a joint statement about "a drastic reduction in the wild boar density, for example through shooting as an effective preventative measure."

Germany has already relaxed some restrictions on wild boar hunting.

Germany's government is also considering new regulations allowing temporary anti-wild boar fencing to be set up to seal off an area should a case be found in Germany, the ministry added.
