When it comes to trying to detect the cattle disease Mycoplasma bovis, it turns out that the tonsils have it.
Dairy farmers are being called to meetings to hear about the programme and get sampling packs individually labelled for their farms.
Meetings were held last week in Central Districts – the lower third of the North Island – and sampling has begun of bulk milk from those farms. Each farmer in the district is then expected to provide samples of non-vat milk from any sick, lame or mastitic cows on two dates -- February 14 and February 28.
Each farm’s contracted milk company will manage the collection of samples.
The surveillance is going nationwide after being carried out in regions with confirmed instances of Mycoplasma bovis – South Canterbury, Otago/Southland and Hawkes Bay.
The meetings were to have been held on February 7-9 in Central Districts, then February 13-15 for Canterbury north of the Rakaia, February 14-15 in Taranaki, February 19-21 in Northland and the South Island West Coast, February 19-22 in Bay of Plenty, February 22-23 in the top of the South Island and February 26-28 in Waikato.
Releasing the schedule of meetings, the head of Fonterra’s FarmSource for Southland, Mark Robinson, said while the sampling was strictly speaking a request rather than a demand, the compliance with the scheme so far had been “pretty good”.
If a farm did not supply samples, then the company would determine whether that was a simple error or the farmer’s decision, in which case the company had the option of taking additional samples from bulk milk.
“In addition to that, it’s likely that MPI might track non-compliant farms and then impose on it an absolute mandatory requirement to supply samples under the Biosecurity Act. I’m hoping it doesn’t get to that point,” said Robinson.
“Most farmers are willing to comply -- for want of a better term -- with this because I think the vast majority understand the importance of understanding how far this thing has spread.”
The testing is a joint effort by all dairy companies, DairyNZ, DCANZ and MPI, who are all working “really well” together to ensure it goes quickly and efficiently, Robinson said.
“It is important that all farmers in New Zealand who are supplying milk for processing to any dairy company participate.
“The information we gain from the surveillance programme will help MPI make the right decisions about what to do next -- whether that is eradication, which is still very much the intention. If it has spread further than is currently known or expected, then obviously the decision might change.”
It is hoped to have results about 10 working days after supply of the second sample vial. MPI will directly contact any farm with suspect results, while processors will contact farms that test clear.
