- On 21 July 2017 samples taken from a South Canterbury dairy herd tested positive for Mycoplasma bovis. This bacterium has never previously been identified in New Zealand.
- On 31 July a second farm was identified as positive.
- The farms are both part of the 16 farm Van Leeuwen Dairy Group (VLDG). All 16 farms have been under MPI movement control through Restricted Place Notices since the start of the response.
MPI has a 3 pronged strategy to managing this outbreak
- Contain – Minimise any further spread of the disease.
The 16 VLDG farms are under Restricted Place Notices that require permits to move cattle between the other farms in the group and transport cattle direct to slaughter at agreed premises. The meat processor has procedures in place to clean and disinfect the transport trucks before they leave the processor.
Each farm has farm hygiene measures in place to clean and disinfect equipment and vehicles that may have come into contact with cows or effluent.
- Survey – How widespread is Mycoplasma bovis?
Before we can make decisions we need to understand where in New Zealand is the disease. MPI has a multi-layered survey that is taking samples from VLDG farms, farms that border VLDG farms, movement traces of stock that have moved to and from farms in the previous 6 months, and a series of regional and nationwide surveys.
MPI is working with NAIT to trace the movements of cattle to and from the Restricted Places over the past 6 months.
- Assess the feasibility of eradication – is it possible to cost-effectively eradicate this disease?
MPI is working with industry and Australian experts to understand the impacts of the disease and the potential costs of eradication. Based on the information from the surveys we will assess the feasibility of eradication.
