Infection positives underline 'protect your patch' message
December 12, 2017
Good on-farm biosecurity and accurate tracing of animal movement is not an option in today’s world, it’s an imperative, Federated Farmers President Katie Milne said.
Positive tests for Mycoplasma bovis in herds in Hastings and Winton (Southland) and a suspected case in Ashburton further underline the need for farmers to treat biosecurity measures on their own properties as a top priority.
Federated Farmers and other industry leaders remain committed to eradicating Mycoplasma bovis, even though today’s announcement makes that a bigger but by no means impossible challenge, Katie said.
"Don’t rely on others to protect your patch, protect it yourself. In the end, we are all biosecurity officers with a role to play."
Establishing a 1.5m buffer along fence lines with neighbouring properties should be standard practice. Where practical that could be a vegetation buffer, which would deliver biosecurity and biodiversity benefits. Close and repeated contact with an infected animal is still regarded as the most likely way Mycoplasma bovis is spread. As one farmer said at a recent meeting, "losing some grazing is a small cost compared to losing your herd".
If vets and AI technicians are visiting your property make sure they have thoroughly cleaned their equipment before they arrive and do so before they leave, and provide hot water and disinfectant for their hands and equipment. Consider making a footbath and a scrubbing brush handy for the boots of all visitors coming onto, and leaving, your farm.
"Think about your own actions too. If you’re visiting a neighbour, clean your boots and any gear you might bring," Katie said.
"Making sure your NAIT records are right up to date, giving special attention to recording stock movements. 100% compliance with traceability requirements [NAIT and Animal Status Declaration (ASD)] is not only vital for biosecurity but increasingly important as we sell our high quality product to discerning customers."
Where practical, limit cattle movements onto your farm. Mycoplasma bovis can be present in apparently healthy animals and there is currently no sufficiently reliable, pre-movement test that can be applied to detect latent or hidden infection. Farmers with leased/loaned terminal bulls may need to think about sending them straight to slaughter. This may well mean a change in practice, but it’s well worth thinking about and discussing with the bulls’ owner.
Federated Farmers does not know who the newly-affected farmers are as their privacy is important, Katie said. "We certainly extend our best wishes to them in what will be a stressful time, and we will continue to work closely with MPI and other sector groups on this sensitive and vital issue.
"Federated Farmers has been helping affected farmers where we can and as we are asked. I encourage any of the new farmers to contact us or their local Rural Support Trust if they have any questions or want assistance."
