Russian officials imposed a cattle quarantine ​in an area of ‌the Chuvash region in the Volga, more than ​2,500 km (1,500 miles) ​west of the Siberian Novosibirsk ⁠region where a ​state of emergency was declared ​over a cattle disease, Interfax news agency reported.

In the ​Novosibirsk region, the forced culling ​of cattle triggered protests by ‌some ⁠small farmers.

Officials said they had identified outbreaks of pasteurellosis in Novosibirsk.

Now, ​the ​bacterial ⁠infection has been identified in the ​Batyrevsky area of the ​Chuvash ⁠region, Interfax quoted a source inside the ⁠local ​agricultural ministry as ​saying.
