BJD Zoning in Australia

Areas are classified as Residual, Control, Protected, or Free, depending on the level of disease and the control measures that are in place.

Each area has to meet specific criteria, and submissions for a change of status have to be acceptable to Animal Health Committee. There are specific requirements that have to be met to move animals from any area to another of a higher status. Contact your State Department of Agriculture for specific movement restrictions in your state.

Current BJD Zones in Australia are:

Free Zones

Free zones are areas where Johne's disease is not known to exist. The only Free zone is Western Australia at this stage. Considerable on-going surveillance is required to maintain Free zone status, and immediate eradication of Johne's disease is required if detected.

Protected Zones

Protected zones are those areas where there is little or no evidence of Johne's disease, there is a high level of confidence that if disease were present it would be detected and on-going surveillance is occurring.

Control Zones

Disease may be present in a control zone however strict restrictions are placed on known infected herds within the zone. Producers in Control zones have a responsibility to adopt best practice when buying stock to ensure their herd does not become infected with Johne's disease.

Residual Zones

Residual zones are those areas where Johne's disease is more widespread or not well defined (insufficient testing has been conducted to determine its prevalence with sufficient confidence). Disease is present but there is little or no official control procedures in place to identify infected herds or reduce the spread of infection.
