More properties in Southland have been placed under notices of direction and a further one under a restricted place notice as Mycoplasma bovis continues to spread in the South.
The Ministry for Primary Industries confirmed last week that, in addition to the three infected properties in Southland, a further four properties in the region had been placed under notices of direction and further one under a restricted place notice.
The flow-on effects of the outbreak are now also being felt beyond the farm gate, some A&P shows having cancelled their cattle sections.
There are at present 14 known infected properties in Southland, Canterbury and Hawke's Bay.
The latest property confirmed with M. bovis was in Ashburton, and the MPI was still trying to establish a link between it and the other infected properties, MPI response incident controller David Yard said.
"In terms of the Ashburton one, we don't have a known linkage as yet, but we have some 30 trace properties to investigate before we have a clear picture of how the Ashburton farm may have been infected."
