Bovine Johne’s Disease Requirements

New information regarding Bovine Johne’s Disease (BJD) biosecurity requirements has been released from both Animal Health Australia and Cattle Council Australia.

Official statements and protocol can be found via the Animal Health Australia Media Release and Cattle Council Producer Update.

Importantly for cattle producers, herds with a transition score of J-BAS 7 or 8 will now revert to a J-BAS 6 rather than J-BAS 0, if no on-farm biosecurity plan is in place by 1 October. You can view each of the J-BAS levels below.

National Requirements by 1 October:

Completed Farm Biosecurity Plan (to be kept on farm – does not need to be submitted)
Completed LPA Accreditation
Completed National Cattle Health Declaration

If you have any questions, please contact your vet or your Animal Health Australia Johne’s Disease State Coordinator.

The new BJD framework focuses on managing on-farm biosecurity risk, rather than just controlling the spread of the disease through regulation and quarantine, as it has in the past. This is achieved through a new system called the Johne’s Beef Assurance Score (J-BAS).

J-BAS is a risk profiling tool developed as part of the new framework and is used as a guide to assist producers in assessing the risk of bringing BJD into their herd and to encourage them to seek further information about the health status of animals that they are looking to introduce onto their property.

The J-BAS score is determined by an individual producer, in accordance with the specifications of the new national industry framework and the producer’s own objectives and disease management. There is no central authority that assigns scores. J-BAS scores are to be declared on Cattle Health Declarations (Q2) and/or National Vendor Declarations (Q9).

Whilst there will be a transition period as the industry’s biosecurity laws move to a nationalised approach – in the longer term, the consistent approach for all states will greatly benefit all producers.

The different levels going forward include:

J-BAS 6

• Complete a relevant biosecurity plan
• Biosecurity plan to be held on farm (basic minimum requirement – this will also be a requirement for LPA accreditation from Oct 2017)
• Does not require a Veterinarian signature
• Required level for entry into NT (please refer to your individual state biosecurity requirements)
• Required level for entry into shows, etc. nationally

J-BAS 7

• Biosecurity plan implemented by 30th June 2017 overseen by vet
• Triennial check test of 50 animals. First test to be completed by 30th June 2018
• Minimum requirement for entry into WA. Check test is also required annually to enter WA.

J-BAS 8

• Highest status
• Check tests of 250-300 animals
• Similar to previous MN3 status

J-BAS 0

• Described as “suspect, infected or unknown” in relation to BJD
