Advice for farm service providers and trucking companies

Those that work with farms have a role to play in helping eradicate Mycoplasma bovis.

Recommended disinfectants

  • 1% Virkon – 50g in 5 litres water 0.2%
  • Citric acid – 1 teaspoon in 1 litre water
  • Trigene – used according to label instructions.


We have a resources library with documents, guidance, and fact sheets you can download on Mycoplasma bovis. It has information for farmers, industry, and the general public.

Keep NAIT and animal movement records up to date

NAIT (National Animal Identification and Tracing) is New Zealand's cattle and deer tracing system and complying with it is law. It's critical that you maintain up-to-date and accurate NAIT and other animal movement records. Accurate record keeping helps us track animal movements and locate any that could be affected. It is also a useful tool for managing your own on-farm biosecurity by providing you a complete history of brought-in animals.

Farm service providers

Farmers should be using routine on-farm biosecurity practices to minimise risk to their animals. Comply with the farm's cleaning and disinfection requirements to help minimise risk.

  • Don't arrive unannounced. Let the farmer know you plan to visit their farm and ask what their requirements are.
  • Work with the farmer to comply with any farm biosecurity requirements.
  • Clean and disinfect footwear, protective clothing, and equipment before coming on the farm and again before leaving the farm.
  • Be proactive – assure farmers of your hygiene practices.

Trucking companies

Work with farmers to meet their hygiene requirements.

All properties under a Restricted Place Notice require permits to move animals on or off the property, including between properties and to slaughter. Places under Notices of Direction require permits to move animals off (but not on to) the place. The permits require the truck to be cleaned and disinfected at the end of each movement.

Moving vehicles to other farms

It is absolutely safe for tradesmen and truck drivers to move from infected farms to other properties.

All infected farms are under strict legal controls under the Biosecurity Act. These controls include a comprehensive cleaning and disinfection protocol, which MPI provided to them. This makes sure vehicles have a very small biosecurity risk.

All vehicles are cleaned and disinfected before leaving properties. Vehicles carrying animals – for example, transporters to the meat processing premises – are disinfected on exit, going directly to the meat processor (not to other farms) and then thoroughly cleaned and disinfected at the plant on completing the job.

Vehicles leaving farms neighbouring infected properties don't need to be cleaned. MPI considers any biosecurity risk from vehicles on uninfected farms to be very small. 

Managing bobby calf movements

There is very low risk of spreading the disease to unaffected farms through bobby calf transport. If you're transporting animals from infected farms or farms under controls, make sure you meet their permit conditions.


Thousands of New Zealand dairy cattle are wintered or grazed off their home farms. There are many ways graziers can protect the health of the stock they manage.

Our winter feeding update gives good advice for graziers moving stock.

Support for farmers

We understand this disease will be stressful for farmers who are affected and farming communities. MPI is working closely with industry organisations, the Rural Support Trust, and government agencies to support people who are most affected.
