In eight localities of the Samara region we have found bird fluAnd much like we saw during the summer of 2017 (see Rosselkhoznador: HPAI Contaminated Poultry Shipped To At Least 9 Regions Of Russia), we are seeing Russian media reports (but few official statements) on the removal of `flu contaminated' poultry products from the shelves in several regions.

Overnight several media outlets are carrying nearly identical reports from the Udmurt Republic.
17 tons of chicken meat contaminated with avian influenza found in shops in Izhevsk
The products were seized and destroyed.
In the shops of Izhevsk found 17 tons of chicken meat infected with avian influenza. According to the press service of the city administration, the products were seized and destroyed.
Meat arrived on the shelves of the city's outlets from disadvantaged regions. Thus, at the beginning of July 28 outbreaks of highly pathogenic influenza among poultry in Kursk, Lipetsk, Orel, Samara were registered in Russia. Two foci of disease at poultry farms in the Penza region.
Sanitary and anti-epidemic commission commissioned the municipal police of the administration of Izhevsk, regional administrations together with law enforcement bodies to organize raids on places of unauthorized trade to stop illegal sale of poultry products
The assumption right now is that Russia is dealing with a relatively low-risk (to humans, anyway) H5N8 virus, but none of the official reports I've seen specify the exact subtype.
Also, it is not entirely clear what is behind this sudden spike in avian flu activity. Wild birds may be carrying the virus from farm-to-farm, or perhaps lateral spread - via the movement of contaminated poultry products, equipment or personnel - may be the driver.
In all likelihood, it will turn out to be a combination of factors.Even after an exhaustive epidemiological investigation of the 2015 HPAI H5 epizootic in the United States - - researchers were unable to nail down a `specific pathway or pathways for the current spread of the virus’.
Regardless, we keep a close eye on these sorts of events because increased HPAI activity over the summer in Russia has previously led to outbreaks in Europe in the fall (see FAO/EMPRES: H5N8 Clade 18.104.22.168 Detected Over Summer In Russia).
