A bird flu prevention zone has been declared across the whole of England.
Six days ago, bird flu was confirmed in 17 birds in the Dorset area, and the declaration comes after 14 more dead wild birds were found with the avian influenza.
This means that all bird keepers have to follow strict measures to in order to reduce the risk of the transmission of the virus to poultry and other captive birds from wild birds or any other source.
These measures apply from today and will remain in force until the declaration is otherwise amended or revoked by further declaration.
Officials say the risk to public health is very low.
