Before committing to a purchase, any purchaser of a farm will want to know that the farm is not under movement control by the Ministry of Primary Industries (MPI) under the Biosecurity Act 1993, and that none of the herd are infected by M. bovis.
Testing for M. bovis is currently underway in a national surveillance milk testing programme being rolled out by MPI, DairyNZ and individual dairy companies. Testing involves the testing of bulk milk and discard milk (from dairy cows with mastitis or suspicious symptoms); the latter having a second test two weeks later to ensure full results are obtained. Testing labs are overloaded and under pressure and test results can take a while to be received.
This puts pressure on timeframes under a sale contract for a farm, delaying purchasers' ability to commit, and certainty for vendors wanting to move on. It has already been an issue for conditional sales contracts this season.
For farmers looking to sell, early action should be taken to minimise the possible impact of M. bovis. As well as continuing to comply with MPI guidelines to limit biosecurity risks, including avoiding herd contact with other livestock and ensuring equipment is thoroughly cleaned, farmers should also ensure their animal health records are up to date and all stock movements are recorded.
Farmers looking to purchase will need to be even more vigilant in their investigation of a farm before committing. As well as ensuring the farm is not subject to an MPI movement control notice, a purchaser should also:
- Receive the results of the bulk milk test on the herd, if it has been completed. Obvious difficulties arise if test results are not available and a purchaser should take proper advice on whether to commit to a purchase before results are received.
- Ask thorough questions about herd movements on and off the property (including where stock were wintered), and if any new stock have been obtained, where they were purchased from and whether they were kept separate from the rest of the herd for a quarantine period.
- Enquire about animal health – including any issues with calf health, mastitis, pneumonia, ear infections and swollen joints.
- Ask thorough questions about biosecurity measures taken on the property.
Purchasers should also ensure their lawyer is familiar with the M. bovis issue. No one solution will apply and sale contracts should include provisions outlining the consequences, both for the land and the livestock purchases, if M. bovis is found on the farm or the property receives an MPI movement control notice. Failure to do so could result in the end of season ownership changes being even more challenging than usual.
