How can I keep my property free of JD?
The following steps will reduce the risk of introducing all strains of JD to your property:
- The highest risk of introducing JD is through introduction of infected animals. Consider using embryos or semen to minimise the risk of introducing JD.
- Intensively grazed animals in high rainfall areas are most at risk of contracting and spreading JD.
- If you do plan to introduce stock, before buying, obtain information to assess the JD disease risk factors via:
- a national cattle health declaration
- a Johne’s Beef Assurance Score (J-BAS) or Dairy Assurance Score.
- Avoid co-grazing cattle with sheep.
- Avoid grazing cattle on land previously grazed by sheep.
- Consider vaccinating sheep to minimise the JD risk from sheep. See the webpage on vaccination of sheep for JD.
Good biosecurity is fundamental to preventing the introduction of all pests and diseases, not just JD. This includes:
- maintaining secure boundary fencing
- preventing access to drainage channels and waterways
- using troughs for watering cattle, and
- ensuring all visitors clean their boots, vehicles and equipment before entering the property.
