The four nations are planning to turn to the EU to help fund a fence that would keep wild boar, possibly infected with African swine fever, from roaming in from Russia and Belarus.
LETA, the national news agency of Latvia, reported Tuesday that the project, which is still being drafted, would see a fence built along the entire border that Poland and the Baltic states share with Russia and Belarus, with the costs for the Lithuanian section alone quoted as 10 million euros.
A second disease-fighting measure under discussion deals with using sniffer dogs to find undeclared meats among passenger luggage. Setting up pig-free buffer zones along border areas has also been proposed.
The virus has been found in Russia in pigs 100 kilometers from the Latvian border, and in Belarus 40 kilometers from the Lithuanian border.
African swine fever is a highly contagious viral disease that affects pigs and wild boar and has a high mortality rate.
