Protection zones have been put in place in two areas of Wales where there are confirmed cases of bird flu.
Cases of avian influenza have been confirmed at a premises near Haverfordwest, Pembrokeshire, on Monday and near Glyn Ceiriog, Wrexham, on Tuesday.
A 3km (1.9 miles) protection zone and 10km (6.2 miles) surveillance zone are in place around each of the infected premises, the Welsh government said.
Protection zones mean stricter measures are in force in the area to contain the disease, while in the wider surveillance zones some restrictions may apply to movement.
The Welsh government said the occupiers of the affected premises must record all movement of people, poultry or other captive birds and their eggs in and out of the zones.
Other steps include the housing or isolating of all birds, a stop to all spreading of poultry litter and manure except by a licensed veterinary inspector, and disposal of bird carcasses in accordance with inspectors’ instructions.
Bird flu, or avian flu, is an infectious type of influenza that spreads among birds and, in rare cases, can affect humans.
There are many different types, but the strains of biggest concern in the UK can be spread by close contact with an infected bird – dead or alive – as well as its droppings and surroundings.
NHS advice urges people to avoid contact with live birds where possible, and to wash their hands often with warm water and soap, especially before and after handling food, in particular raw poultry.
Other tips for avoiding the spread include using different utensils for cooked and raw meat, making sure meat is cooked until steaming hot.
