The movement of cows, sheep and pigs is now banned within a 10km restriction zone around a farm in Nafferton, where bird flu was discovered last weekend.
Since Thursday November 20, farmers have been told they must apply for licences if they wish to move any animals from premises where poultry is kept.
It’s understood there are around 100 farms and smallholdings within the zone which keep poultry.
The ban means that such farmers and smallholders now need to apply for a licence if they wish to move livestock - even within their own premises, for example to a neighbouring shed or field.
Farmers without poultry are not affected by the ban.
The Animal Plant and Health Agency (APHA), which has imposed the ban, says that any licenses, if granted, will only allow a one-off movement and will be subject to certain conditions based on disease control risk.
A spokesman said: “We’re taking immediate and robust action and an investigation is underway to understand the origin of the disease and confirm there are no further cases.”
APHA says it may grant licences for certain movements, including:
-movement of mammals from premises with poultry on the restricted zones to slaughter
-movement of poultry from the restricted zones to slaughter
-movement of table eggs from the restricted zones to a designated egg packing centre
-movement of hatching eggs from a premises in the restricted zones to a designated hatchery
The APHA says it may consider further licences for other movements or activities in due course.
