Federated Farmers is updating its contracts to include provisions for sharemilkers and sharemilker farm owners to develop a farm biosecurity plan.
"A viable sharemilking industry has long been a key part of the vibrancy and innovation of the dairy industry," sharemilker farm owners chairman Tony Wilding said.
"With the Mycoplasma bovis incursion, and the decision to try and eradicate the disease, an extra challenge has been put in front of us."
In the past a biosecurity plan had been sensible business practice under the sharemilker/farm owner model, but now it was an imperative, he added.
Sharemilkers chairman Richard McIntyre said there was plenty of advice at www.dairynz.co.nz/animal/cow-health/mycoplasma-bovis/, including the kinds of questions that need to be asked if new stock was coming on to the farm.
