With the advent of Autumn, the European Union issued a warning to poultry producers to maintain vigilance against introduction of avian influenza.

According to an October 1st report in Reuters "EU countries are being urged to step up surveillance and biosecurity measures to guard against possible new outbreaks of avian influenza this year".  Migratory waterfowl have yielded avian influenza virus on surveillance  in the eastern Russian Federation and Kazakhstan.

The advisory issued in the EU should also apply to the U.S. given the seasonal introduction of avian influenza by migratory birds. Subsequent to the HPAI epornitic in 2015, both structural and operational biosecurity has improved on most commercial operations. Unfortunately with the passage of time there has been some erosion in implementation of protective measures.
