Expanding Control Zones: Norfolk’s Battle Against Blue tongue Outbreak

Norfolk’s livestock farming community faces a heightened challenge as the bluetongue control zone expands in response to new cases of this potentially fatal animal disease. Bluetongue, affecting ruminants such as cattle, sheep, goats, deer, and camelids, has raised concerns after the confirmation of two infected cattle on a holding near Norwich. The total number of cases in the county has now reached 21 since the initial discovery on a Cantley farm in the Broads on December 8, signaling the need for increased vigilance and control measures.

 Blue tongue

The regulatory authority in charge of such matters, the Department for Environment, Food & Rural Affairs (Defra), recently confirmed the extension of the temporary control zone (TCZ) in response to the latest developments. This 10-kilometer zone was initially established to facilitate focused surveillance efforts and restrict livestock movements, aiming to prevent the disease’s further spread. All preceding cases were contained within the TCZ, but the most recent instances involved animals grazing just outside the zone during a high-risk period. Consequently, the TCZ’s boundaries have been adjusted, extending it toward Norwich to address this evolving situation effectively.

An interesting departure from previous protocol is the decision not to cull the infected animals this time. Defra has opted for an alternative approach, restricting these animals at their current locations and implementing disease mitigation measures. This strategic shift is attributed to a recent reduction in midge activity, diminishing the risk of onward transmission. The link between bluetongue and infected midges is crucial to understanding its spread, as it is believed that the disease was introduced to Norfolk and Kent by these tiny vectors, carried across the Channel from Europe during optimal wind and temperature conditions in September or October.

However, despite the absence of evidence suggesting the disease’s circulation through midges in the UK, precautionary measures within the TCZ are causing disruption and uncertainty for local livestock farms. Specific licenses are now mandatory for moving animals out of the zone, with permission granted only under circumstances of “urgent and genuine welfare need” or for direct transportation to a designated abattoir. This has added an extra layer of complexity for farmers who must navigate these restrictions while ensuring the well-being of their livestock.
