A Whanganui property has been placed under "low-level" controls in the fight to contain Mycoplasma bovis.

But the Ministry of Primary Industries says there has been no detection of the disease in the Whanganui area.

About 30 properties - all but one in the South Island - have Mycoplasma bovis and last week MPI confirmed more than 20,000 cattle will be culled in a bid to contain the disease.

An MPI spokesperson said the Whanganui property which was under movement restrictions was identified as a result of tracing activity from other affected farms.


"There is a property in the Whanganui area that has been placed under low-level movement controls restricting the movement of risk goods off the property.

"There are many farms across the country under similar restrictions and this is not an indication that the property is positive for the disease."

The restrictions are in place while MPI undertake investigations.
