Footrot
Footrot management
- Footrot is a notifiable disease and sheep infected or suspected of being infected with any form of footrot must not be moved within or into the state without Chief Inspector of Stock (CIS) permission. Find out more about moving sheep.
- Interstate sheep infected or suspected of being infected with any form of footrot are not permitted to enter South Australia without CIS permission
- The July 2019 version of the NSHD must be completed for all movements of sheep within and into South Australia and you must declare all forms of footrot; both benign and virulent.
- There will be increased ability for infected producers to trade sheep based on their flock's diagnosis. Buyer beware means you need to check the status of animals before you purchase – check the NVD and NSHD. Movement restrictions into South Australia remain in place.
What is footrot
Footrot is a contagious bacterial disease in sheep. Footrot is classified as inflammation of the interdigital skin and potential under-running of the hoof caused by the bacteria Dichelobacter nodosus (D. nodosus).
It can cause significant economic loss to producers through reducing:
- ewe fertility
- wool growth
- growth rates
- sheep sales.
Controlling or eradicating footrot can be costly; however, the long term benefit of eradicating footrot from a flock far outweighs the cost.
Footrot is a notifiable disease and suspicion of any form of footrot must be reported immediately.
Development of footrot
Like all diseases, there are 3 main factors that affect the development and severity of footrot in a flock:
- Agent – in the case of footrot this is the bacteria D. nodosus and the potential virulence of the strain of D. nodosus present in the flock.
- Host – how susceptible the sheep in the flock are to footrot. No breeds of sheep are resistant to footrot, but some are more susceptible than others.
- Environment – footrot requires warm moist conditions to develop and adequate pasture length to enable transmission of the bacteria from sheep to sheep.
The map below shows areas of South Australia where footrot investigations have recently occurred.
How footrot is diagnosed
There are 2 main ways to diagnose footrot in a flock. Both require the inspection of a significant number of sheep:
- Clinical diagnosis – where it is possible to inspect sheep during a 'spread period' (warm, moist with adequate pasture length) hooves can be inspected and pared to reveal the most severely affected sheep in the flock. The percentage of sheep suffering severe footrot lesions can then be used to form a diagnosis of benign or virulent footrot.
- Laboratory based diagnosis – the time of year, local climate and other management factors do not always allow for an accurate clinical diagnosis, especially during dry times or in traditionally drier parts of the state. For this reason the South Australian Footrot Management program utilises a laboratory test called the 'Elastase test' to assign a flock diagnosis. By submitting samples from multiple infected sheep across the flock, the Elastase test can return results which indicate how severe a footrot infection may be under ideal development conditions.
When a flock has footrot
If a flock has been detected with footrot, there are movement restrictions that apply under the South Australian Livestock Act 1997.
When there is a suspicion a flock has severe virulent footrot, sheep:
- cannot be sold to other graziers
- must not be sold in a public market
- must not be allowed to stray onto public roads or neighbouring properties.
Sheep with footrot can be sold directly to an abattoir for slaughter or slaughter through an approved feedlot. They must be fit to load – being able to bear weight on all 4 feet prior to transport.
