The Kremlin’s ban on many imported foods from the European Union, the United States and a number of other Western countries is reported to be already pushing up prices in Russian shops.

Local officials said pork was up by six percent in Moscow supermarkets since the self-imposed food sanctions took effect on August 7. Fish, milk and cheese prices has also risen.

Elsewhere even bigger jumps have been recorded, with chicken pieces reportedly costing 60 percent more on the island of Sakhalin.

The one-year ban is in retaliation for Western sanctions on Moscow over the Ukraine crisis.

The prime minister’s office is promising that alternative sources will be available soon.

Russia previously imported half the fish, milk, beef and cheese consumed there.
