The Chief Veterinary Officers from England, Scotland and Wales on Monday declared an Avian Influenza Prevention Zone across Britain due to an increase in the detections of avian influenza in wild birds and on commercial premises, Reuters reported, citing the government as its source.

From midday on Monday it will be a legal requirement for all bird keepers in Great Britain to follow strict biosecurity measures, including keeping free range birds within fenced areas, the government said.

Other measures include keepers with more than 500 birds will need to restrict access for non-essential people on their sites, changing clothing and footwear before entering bird enclosures and cleaning and disinfecting site vehicles regularly.

Britain has faced its largest ever outbreak of avian flu with 190 confirmed cases since late October 2021, with over 30 of these confirmed since the beginning of the month, the government said.
