Officials said seven workers at a poultry plant in the south of the country had been infected following an outbreak there in December.
"All seven people... are now feeling well," said the head of Russia's consumer health watchdog, Anna Popova.
She said that adequate measures had been quickly taken to stop the spread of infection.
There was no sign of transmission between humans, Ms Popova said, adding that the case had been reported to the World Health Organization.
