"Industry and government must have a high degree of confidence from global scientists that eradication is both feasible and practical", he said. "So if we have an opportunity to be the country that eradicates this disease, then we'll take it". In cattle, casualties are recorded due to the respiratory diseases triggered by this bacterium which is responsible for a third of all the respiratory infections in cattle. On their farm, Jan and her family use corgis as herding dogs and have raised Shetland sheep, Fainting goats, Morgan and Trakehner horses, and historic breeds of chickens and turkeys.
The problem with Mycoplasma bovis is that it's hard to detect and doesn't respond to antibiotics.
All cattle on infected farms and future infected farms, plus some high-risk farms under movement controls, will need to be culled.
A cow is seen near the fence of a pastoral farm near Auckland August 6, 2013. This is in addition to the current cull underway. There is also an impact on production that has serious ramifications for farmers, the dairy sector and our economy.
"This was not an easy decision to make for those reasons, and our hearts and thoughts are with the farmers that have affected herds". This tracing, testing, and culling will continue until ongoing regular surveillance finds no remaining evidence of Mycoplasma bovis.
Cabinet's decision has the support of Federated Farmers and the NZ Veterinary Association, although the former is well aware of the emotional and psychological effect on farmers.
The cull will be managed by the Ministry for Primary Industries, which has not covered itself in glory on this issue.
Ardern said today's decision will provide farmers with some certainty, but recognizes how painful a loss this is for farmers who are directly affected.
"Farmer welfare is crucial and I'd like to thank the Rural Support Trusts for the work they're doing". MPI says a substantial part of a farmer's claim for culled cows should now take 4-10 days, with a fully verified claim taking 2-3 weeks.
A much better performance is needed in managing the cull.
It was going to be a long process and the only way the farming sector would get through it was if it was united in the fight, whether caught up in the process or not, she said.
The disease doesn't affect humans and is spread between cattle by semen, milk and nasal fluids.
