Vladimir Putin has banned the import of agricultural goods from countries that have imposed sanctions on Russia.
Russia is Europe's second largest market for food and drink and has been an important consumer of Polish pig meat and Dutch fruit and vegetables. Exports of food and raw materials to Russia were worth €12.2bn (£9.7bn) in 2013, following several years of double-digit growth.
The UK is less likely to lose out; in 2013 its biggest food and drink export was £17m of frozen fish, followed by £5.7m of cheese and £5.3m of coffee.
Russian officials are reported to be considering banning European airlines from flying to Asia over Siberia.
