Bovine tuberculosis bTB caused by Mycobacterium bovis is an important livestock disease raising public health and economic concerns around the world.
In New Zealand a number of wildlife species are implicated in the spread and persistence of bTB in cattle populations most notably the brushtail possum Trichosurus vulpecula. During the next 50 years several initiatives were taken to control bovine tuberculosis. Tackling bTB the New Zealand way.
From 19791984 possum control was stopped due to lack of funding. The control and eradication of bovine tuberculosis TB is the single largest investment of the milksolids levy. Bovine tuberculosis bTB is a disease of international significance and zoonotic potential.
Tb-infected herds first-time fall below 100. In the UK the bulk of the budget still goes on testing and compensation 80. In 2016 the New Zealand government and agricultural industries jointly adopted the ambitious goal of nationally eradicating bovine tuberculosis TB from livestock and from all wildlife reservoirs by 2055 1 2.

In these areas nearly 70 per cent of new herd infections can be traced back to possums or ferrets. The problem of bovine TB has been described by the Ministry for Research Science and Technology as the greatest challenge currently facing New Zealand science. Numbers are in New Zealand dollars.

Bovine tuberculosis is currently 2012 endemic in possums across approximately 38 per cent of New Zealand known as vector risk areas. World bovine tuberculosis experts gather in Wellington New Zealand in August 2009 for the 5th International Bovine Tuberculosis Conference. It would appear that the epidemiology of the disease is determined by the behaviour of both wildlife and domestic stock and environmental influences on the development of the infectious state in wildlife.
The primary wildlife reservoir of bTB in New Zealand is the introduced brushtail possum Trichosurus vulpecula 1. In New Zealand bTB has been present in domestic cattle since the 1800s. This is because it threatens NZ36 billion dairy beef and deer export markets and because the presence of persistent wildlife reservoirs has seriously limited efforts to control the.
