An employee sorts fishes at a fish department of a Carrefour grocery store in Brussels September 4, 2014. Russia, which is the EU's second biggest food market after the United States, decreed the one-year ban on Aug. 6. on European fruits and vegetables, dairy products and meat, accounting for almost half of the bloc's food exports to Russia. Russia's ban on imports of food from Europe, part of its response to EU sanctions imposed over the Ukraine crisis, could cost the European Union 5 billion euros ($6.6 billion) a year, according to an internal EU document seen by Reuters.
