Serbia's Customs Administration is already on heightened alert, trying to do its best to prevent the pork from reaching the country's markets.
"All the customs services have been ordered to be on standby and especially focus on the checkpoints located near Serbia's border with Montenegro, Macedonia, Bosnia-Herzegovina as well as the administrative border with Kosovo," the Customs Administration was quoted by the Evening News as saying.
The trouble is that the meat can be illegally transported to Serbia, especially thorough Kosovo, according to the newspaper.
The invasion of frozen thirty-four years old pigs was first reported by the web portal Agroservis, but the sources did not elaborate on who might be the customer for this frozen pork which is due to be delivered to Serbia via Montenegro's port of Bar, the Evening News said.
Meanwhile, social network users have said that frozen meat from US has been supplied to Bar over the past twenty years and that the product is then purchased by Serbian processing companies.
In February 2016, Serbian President Tomislav Nikolic signed a confirmation of the country's cooperation plan with NATO, triggering a series of anti-NATO protests. Serbian Prime Minister Aleksandar Vucic said, however, that his country does not intend to join NATO as the country "zealously" adheres to neutrality.
