Trading sheep

The main way ovine Johne’s disease (OJD) first arrives on a property is on the back of a truck.

The most likely way for a flock to become infected with OJD is through the introduction of infected sheep, which makes infected flocks a risk for a region and the whole sheep industry. Once the disease is established in a region, there is an additional risk of it spreading laterally from infected flocks to neighbouring areas.
