A fresh outbreak of African swine fever was fixed on Friday in the Uryupinsk district of Russia's Volgograd region, a regional government source told Itar-Tass. The source said the diagnosis was confirmed by a Volgograd district veterinary laboratory. On Thursday, an outbreak of ASF in the Uryupinsk district was fixed in a private household in the Besplemyanovsky farm. "As farms of the whole Uryupinsk district get within the first threatened zone, it was decided to impose quarantine on the territory of the region," the press service of the regional government reports. "In order to liquidate ASF centers and to prevent a further spread of the dangerous infection across the Volgograd region all pigs must be slaughtered," it said. According to preliminary data, over 10,000 pigs are to be culled. This is already the second district in the Volgograd region where all pigs are to be slaughtered because of African swine fever. Earlier, about 6,000 pigs were slaughtered in the Alekseyevsky district. About 1,000 pigs were culled in the Nekhayevsky and Serafimovichsky districts.
