The bird flu protection and surveillance zones imposed following the outbreak of the disease in Suffolk are to be lifted, Defra has said.
The source of the outbreak in Suffolk remains unknown
If there are no further cases, the first protection zone will be lifted on 8 December, followed by the second protection zone on 10 December.
The wider surveillance and restriction zones imposed in November are due to be lifted on 19 December.
Other restrictions on bird movements and gatherings will remain in place.
The measures were put in place to protect birds from the H5N1 strain of avian flu following an outbreak at the Redgrave Park farm on the border of Norfolk and Suffolk on 13 November.
The virus had also spread to the nearby Hill Meadow farm which shares its workforce with Redgrave Park.
Defra has been unable to confirm the source of the outbreak but has not ruled out wild birds as being the cause.
Millions of birds worldwide have either died from the H5N1 strain, or been killed to prevent the spread of the disease.
Other restrictions on bird gatherings and movements of poultry and poultry meat within the zones will remain in place.
