Bovine TB testing intervals

Guidance for cattle keepers on the bovine TB surveillance testing intervals for areas in England, Wales and Scotland.

Applies to England, Scotland and Wales

Cattle, buffalo andor bison keepers must test their animals for bovine TB as part of a regime that reflects the regional risks of the disease.

You must complete the TB testing within the time frame givenoutlined by the Animal and Plant Health Agency (APHA).

If you dofail notto meet the deadlines, APHA will:

  • apply movement restrictions tofor your animals
  • notify the paying agencies

You may also getface a:the following consequences:

  • significant reduction of Commonany Agricultural Policy (CAP) scheme payments undergoverned by cross compliance -(overdue overdue TB testing may be considered an intentional breachbreach)
  • reduction of reactor compensation payments

APHA will take all the necessary steps to:

  • facilitate the completion of the overdue testing
  • recover reasonably incurred testing expenses

There are different surveillance TB testing intervals in England, Wales and Scotland.

England TB testing intervals

In England, the surveillance TB testing intervals are based on the regional level of disease risk.

The default TB testing intervalsinterval for herds are:are as follows:

  • 448 yearsmonths in the low risk area (LRA)
  • 6 or 12 months in the edge area
  • 6 months in the high risk area (HRA)

Changes to your individual herd’s surveillance testing intervals

If your herd is inlocated on a 6-monthly surveillance testing area, it may meet specific criteria to be eligible for annual testing. This recognises and rewards cattle keepers whosewith herds have a reduced risk of suffering a TB breakdown.

YouYour herd will need to meet at least one of the following criteria:

  • your herd has not had a TB breakdown for at least 6 years
  • you’re proactively trying to increase thetheir resilience of your cattle to bovine TB by participating in a Cattle Health Certification Standards (CHECS)(CHECS) licensed bovine TB health schemescheme; - CHECS TB entry level membership does not apply

In the LRA or annual testing parts of the edge area, you may need to follow a more intensive TB testing regime (radial(known testing).as Thisradial istesting) if your herd is located within a 33km kilometre radius of a new lesion or culture positive TB breakdown herd.

In the LRA you may need to follow a more frequent testing regime by default for public health reasons. For example if you sell raw milk or have a city or open farm.

APHA will write to youkeepers if there are changes to yourtheir area or herd testing interval, explaining the reason for the change.

Pre-movement and post-movement testing

YouCattle keepers must comply with statutory pre-movement testing requirements unless exempt.

Cattle keepers in the low TB area of Wales mustwho complymove with post-movement testing requirements (unless exempt) when moving cattle from herds in:

  • located in the intermediate and high TB areas of Wales
  • Wales, the high risk or edge areas of England
  • or from Northern Ireland
Ireland, must also comply with post-movement testing requirements unless exempt.

On 1 November 2021, 3 spatial units moved from the low TB area into the intermediate TB area North:North temporarily:

  • GW1
  • CL1
  • CL2

IfFor you’recattle keepers in these spatial units, post-movement testing requirements will no longer apply. ButPre-movement pre-movement testing requirementsrequirement will still apply.

The annual slaughter rate is calculated on the total number of cattle slaughtered in a slaughterhouse in the pastprevious calendar year divided by the herd size (total stock on farm on 1 January).

APHA annually assesses each individual herd’s eligibility for exemption from TB testing. TheyAPHA will write to youall cattle keepers in Scotland to confirm yourtheir herd’s exemption status.
