APHA’s Edge Area Bovine TB Epidemiology Reports for 2023

How’s it going?


The quotes in the table below are taken from the APHA county epidemiology reports recently released. Progress is clearly not on target. As seen in Oxfordshire (see here), bTB in the Edge Area is not being addressed with sufficient resources or the right approaches. The lack of adequate testing is so glaringly obvious it is beyond belief that this situation is being allowed to continue. The bovine TB eradication policy is in tatters not just in the HRA and LRA but in the Edge Area too.

Progress

Going Well?

Berkshire

“Looking at the recent trend, the likelihood of achieving a herd prevalence of less than 1% OTF-W incidents in Berkshire by 2025 is low.”

No

Buckinghamshire

No prediction

?

Cheshire

“..the prevalence (4.4%) in 2023increased marginally compared to 2022. OTF county status will not be achieved by 2025,but with the use of all available tools to identify and to reduce the burden of infection, it might be possible to achieve OTF status by 2038.”

No

Derbyshire

“Based on current information, achieving OTF status is not conceivable for Derbyshire by 2025. Residual infection continues to be a problem in Derbyshire. The reasons for this are unclear, may be multi-factorial, and is likely to include herd type, wildlife populations, farming practices and proximity to the HRA county of Staffordshire.”

No

East Sussex

“The increase of prevalence rate from 2022 in addition to the geographical extension of the endemic area (HRA prior to 1 January 2018) suggests that East Sussex will not be able to achieve OTF status by 2025. The prevalence and incidence will need to have a considerable reduction through the next 10 years to ensure that OTF status in the county could be reached by 2038.”

No

Hampshire

“The likelihood of achieving a herd prevalence of less than 1% OTF-W incidents in the county by 2025 is low.”

No

Leicestershire

“Although the herd incidence declined again in 2023, it is unlikely that Leicestershire will achieve OTF status by 2025.”

No

Northamptonshire

“Despite the declining herd incidence and prevalence trends over the last 3 years in Northamptonshire, it seems unlikely that the county will be eligible for OTF status by 2038.”

No

Nottinghamshire

“Additionally, prevalence in Nottinghamshire at the end of the reporting year was 1.7%. It seems unlikely for Nottinghamshire to become eligible for OTF status by 2025, as set out in the strategy for achieving OTF status for England, published in 2014. However, if the disease trend continues to decline as a result of effective disease control measures it is possible Nottinghamshire will achieve OTF status by 2038.”

No

Warwickshire

“Official-TB-Free status (OTF) for Warwickshire will not be achieved by 2025, as set out in the ‘Strategy for Achieving OTF Status for England’, published in 2014. However, progress is being made and the outlook is positive.”

No

 


Recurrence

Recurrence’ is where bovine TB returns to a herd after a period when it has not been detected by periodic testing. Recurrence is the result of residual infection, ineffective testing and cattle movements, (with the odd unevidenced nod to wildlife). Recurrence is now recorded consistently across the Edge Area and the High Risk Area, and it is the reason why the Edge Area is unlikely to be TB free by 2038. APHA diverted gamma testing in 2021 to herds with a history of recurrence and persistence, at the same time reducing parallel testing of gamma alongside the skin test in OFT-W (Officially TB Free Withdrawn) herds, resulting in early undetected disease remaining in herds throughout the Edge Area.

It’s interesting to note that ‘Overall Recurrence’, ie recurrence during the herd’s lifetime, has been added to the recently published epidemiology reports (see below). Previously, recurrence has only related to the previous 3 years.  ‘Overall Recurrence’ reflects the true seriousness of the epidemic. 

And alongside the reality of the problem of Recurrence, the APHA are still blaming badgers for significant disease transmission without evidence, and still claiming disease benefit from badger culling without evidence.
