Pigs are seen in a piggery at a village near

Pigs are seen in a piggery at a village near Warsaw April 10, 2014. Poland has asked the European Union to intervene in a spat over Russia banning imports of Polish pork and says that the case could be taken up by the World Trade Organisation (WTO). Russia suspended imports in February, citing concerns that cases of African swine fever among wild boars in Poland could spread to farmed pigs.
