How points are allocated to prevalence areas
On 1 January 2011 the status of some prevalence areas changed because of an increase in the regional prevalence of ovine Johne’s disease (OJD).
From 1 January 2011 there are two Prevalence Areas in Victoria. The Shires of Mildura, West Wimmera, Glenelg, Hindmarsh, Horsham, Gannawarra, Yarriamback, Buloke and Swan Hill will be in the Medium Prevalence Area. The remainder of Victoria will be a High Prevalence Area.

| Prevalence Areas at January 2011 | Points allocated under Category A on the Sheep Health Statement | Maximum estimated % of infected flocks within the prevalence area1 | |
|---|---|---|---|
| Low Prevalence | 4 | 0.8 | |
| Medium Prevalence | 2 | 12.5 | |
| High Prevalence | 0 | >12.5 |
1Maximum estimated % of infected flocks within the Prevalence Area is measured at the upper confidence limit.
What do the changes mean for me?
You should check the map before you fill out a Sheep Health Statement to find out your new Prevalence Area and the appropriate ABC credit.
You can still get trading credits for vaccination, testing for OJD, for Abattoir Surveillance 500 and 150 tests and for the certification of low risk sheep; these all stay the same.
Why some prevalence areas have been reclassified in January 2011.
- Abattoir surveillance from the previous two years showed that the prevalence of OJD was increasing in some parts of Australia. Based on this information, stakeholders agreed that prevalence areas should be reclassified or boundaries modified to more closely quantify the true risk that sheep from these areas represent.
- Sheep producers need to be confident that the sheep they buy have the level of assurance they expect.
