When infection is confirmed on a property we begin the process of tracing cattle movements on and off that property.
We look at movements:
We find most of our traces through:
As traces are made they are passed on to our Casing team for information gathering.
See below for the types of traces we are looking for and their impact.
A forward trace is where cattle have moved off an infected farm during the risk period of likely infection.
The farms that those cattle have moved to are assessed to see if they need to be placed under restrictions while testing is done to determine if the infection has spread there.
A Backward Trace looks at cattle that came on to the property before and during the time it was infected, (so could have been the source of the infection).
