From last week the cows have been dining on brie, camembert and chorizo -- all foods which fall foul of the ban.
Until now, food found by government inspectors to be from Europe and North America was simply returned to its country of origin.
But now authorities in Russia are planning to turn the produce into “high-protein flour” for livestock. A spokesman for the agricultural safety regulator says meat and dairy products can be used as raw materials for high-protein flour to be added to food for livestock.
