As well as finding disease in your herd, it is also important to prevent the spread of TB to other herds and wildlife. The biosecurity ‘Five Point Plan’ developed by Defra and industry partners contains useful recommendations for practical measures you can implement on your farm


Five point plan

Cleansing and disinfection (C&D)

You will be sent a Notice requiring Cleansing and Disinfection (BT05) at the beginning of the breakdown explaining what you need to do after reactor cattle have been removed. This form has a declaration that needs to be returned to APHA to confirm that you have carried out cleaning and disinfection after the removal of reactors to slaughter. It is important to return the form to APHA promptly as movement restrictions cannot be lifted at the end of the breakdown without a completed declaration. If you cannot find the original form, a replacement BT05 can be downloaded from GOV.UK.

C&D is important as M. bovis can potentially survive for months in the environment, especially in cool, moist and dark places. Studies show it can survive for:  


Medium Survival time
Water 20-60 days, depending on the conditions
Soil Up to 14 days (summer) and up to 3 months (winter)
Stored slurry Up to 6 months
Cattle faeces on pasture Up to 2 months (summer) and up to 6 months (winter)


Management of Slurry and Manure

As part of the Notice of Cleansing and Disinfection (BT05), you need to clean and disinfect the area where the reactor was isolated and any relevant equipment, vehicles or facilities used:

  • Before removal, if possible, bedding and manure should be sprayed with a Defra approved disinfectant. It is important that you follow the manufacturer’s instructions carefully to achieve the correct dilution rate otherwise it will be less effective (if at all). See our worked example below for further guidance. Remember to not just clean at ground level and to also clean the walls up to the height of the cattle to ensure nasal/faecal contamination is removed
  • Once this has been done, remove the bedding and manure and stack it for at least three weeks in a place where it is inaccessible to livestock and wildlife. Ideally spray the top of the manure heap with an approved disinfectant or cover with a layer of earth
  • After removal of manure and bedding, thoroughly scrape out the area if necessary, and clean and disinfect any equipment used
  • Equipment used on/for reactor cattle (e.g. feed and water troughs, milking equipment) should be thoroughly cleaned and disinfected
  • If reactor cattle were isolated at grazing then some of the above may not apply and there is a tick box on the BT05 declaration to this effect

For more information about how to correctly calculate disinfectant dilution rates, read our worked example

It is strongly recommended that you do not spread the stacked manure from reactor cattle on pasture. If you do choose to spread this manure, it is strongly recommended that cattle do not graze the land for at least 60 days after its application. This is to allow for the natural die-off, decay and inactivation of any M. bovis bacteria that may have contaminated the environment.

If you choose to spread slurry, it should be stored for as long as possible before use, ideally for a minimum of six months. Slurry must not be spread within a minimum of 10 metres from your farm boundary or from any land grazed by or housing used by any TB susceptible stock. Ideally, there must be no access to the treated ground by TB susceptible stock for at least 60 days following spreading of slurry.

  • If at all possible, slurry should be spread in calm weather to minimise aerosol production
  • Methods of slurry spreading that produce aerosols that travel long distances should be avoided where possible
  • Slurry application should be avoided outright when cattle are in neighbouring fields and when slurry risks drifting into neighbouring grazing fields, even if there are no cattle in them. Slurry from other farms should not be spread and you should avoid sharing spreading equipment with other farms. If this is unavoidable then all equipment should be thoroughly cleaned and disinfected between farms

Slurry from other farms should not be spread and you should avoid sharing spreading equipment with other farms. If this is unavoidable then all equipment should be thoroughly cleansed and disinfected between farms.

TB Advisory Service (TBAS)

Farmers can do a lot to reduce the risk of TB entering their cattle herd and in minimising its impact if they do get it. While the TB Hub and private vets remain great sources of information and advice, farmers can now benefit from the TB Advisory Service (TBAS) too.  

TBAS for slidedeck

TBAS was launched in 2017 and cattle farmers in the High Risk and Edge Areas of England can register for the service by telephone and email.

TBAS aims to help maximise farm biosecurity and minimise TB risks associated with cattle movements. They offer on-farm visits, telephone advice and drop-in clinics for cattle keepers free-of-charge.

Farm visits typically last around two hours, depending on how much there is to look at and discuss. After the visit, you will receive a bespoke report including practical recommendations. You are encouraged to also invite your private vet to the farm visit and to share the report with them afterwards. Further advice and support over the phone is available after the visit.

Disease Investigation Visit (DRF Visit)

This visit is completed by an APHA vet, primarily to gather information about the source of the TB breakdown. Advice will also be given on biosecurity and the APHA vet will answer any questions that you may have, for example regarding TB licensing. All new TB breakdowns in the Low Risk Area (LRA) and Edge Area receive a visit by an APHA vet, known as a DRF (Disease Report Form). In the High Risk Area (HRA), this process is slightly different as not every TB breakdown receives a DRF visit.

APHA will contact you to arrange the visit. The aim of this visit is to try and establish the source of the TB breakdown and inform case management. If you are not visited, you will be contacted by telephone so that APHA can gather certain information that will help to manage your breakdown and instruct any additional TB testing that may be required. The following information is gathered by the APHA vet at the visit:  


Herd data Basic data such as herd size, cattle type, system and business type  
Mapping of the farm Using data held by the Rural Payments Agency (RPA), APHA generates maps to show all the various premises and land used by the herd, along with areas of possible contact with other neighbouring cattle herds  
Non-bovine species APHA will ask about other livestock species kept on the farm that are susceptible to TB e.g. camelids, goats and pigs  
Previous TB testing and breakdown history APHA will establish if this is a first TB breakdown or not and gain further details about the reactors found  
Wildlife activity APHA will ask about badger activity and setts on the farm and in the surrounding area. They will also ask about wild deer  

APHA will ask questions about:    

  • Policy for introducing new animals onto the farm·        
  • Whether badgers or deer can access cattle feed, water and housing       
  • Milk source used for calves (if applicable)        
  • Silage type fed on farm and its origin
Public Health APHA will ask about the sale of raw milk and raw milk products (if applicable) and also whether any family or staff members consume raw milk from your herd  


Farm Level TB Reports

Owners of all new TB breakdown herds in the HRA and Edge Area receive a farm level TB report a few weeks after the start of the breakdown. The reports are specific to the individual farm and you are encouraged to share the report with your private veterinary surgeon to get the most out of it. These TB reports are produced by APHA using TB breakdown and cattle movement data. The aim of the report is to help you understand the TB risks to your herd and how to take action to reduce these risks. For more information about how farm level TB reports can help you and your private vet, see our guide
