Help available for flood-hit farmers
The chair of the Otago Rural Support Trust, Tom Pinckney, says he believes that they will be especially busy in the coming months as the enormity of the floods hit home.
The review was commissioned by MPI, DairyNZ and B+LNZ last year after it became apparent that infection was circulating in a small geographical area despite the use of disease control measures, which have proven successful in other areas around NZ.
The review, carried out by epidemiologist Dr John Happold, could not confirm the sources of infection in Wakanui but says that the area has been unique to other parts of NZ which have experienced the M. bovis infection.
Happold believes the unusually high amount of infection on the Five Star Beef feedlot could have allowed for airborne transmission – something that is highly unlikely to have occurred in other areas of NZ.
MPI’s M Bovis programme director, Simon Andrews says Wakanui had a large, concentrated, and dynamic population of infected animals within the local feedlot.
He says there was also a small cluster of other confirmed properties, most of which have paddocks adjacent to the feedlot.
He says the reviewer was not able to determine the transmission routes occurring in Wakanui with any certainty and says it’s possible these may never be known.
“What we do know is, eradication is not dependent on knowing the transmission route. What is important is that we remove the infection from the area which is exactly what we’re doing.“
As part of the review, Happold also looked at a range of transmission routes including mechanical vectors such as birds and flies, manure, effluent, and groundwater. He concluded infection is unlikely to have occurred via these routes. In his report, Happold supported the depopulation plan for Five Star Beef and the use of a Controlled Area Notice (CAN).
Andrew says the eradication effort continues to make good progress and that the high-risk area of the CAN is now free of cattle and the CAN is on track to be lifted in mid- March.
He says it’s expected all current Confirmed Properties are likely to be cleared within the first half of this year.
“While the job is far from over, we are as close to moving to the next phase of the eradication as we have ever been and the collective effort from farmers, industry and Programme staff has helped us get to where we are today,” he says.
The Mycoplasma bovis Eradication Programme began in May 2018 and is jointly funded by Government (68%) and DairyNZ and Beef + Lamb New Zealand (32%).
Just over 3 million tests have been completed, $234 million has been paid out in 2838 claims and 180,872 cows have been culled.
