Mycoplasma bovis

The New Zealand Veterinary Association (NZVA) is supporting veterinarians to help farmers respond to the detection of Mycoplasma bovis in a dairy herd in South Canterbury/North Otago.

Find resources for veterinarians and links to updates on the response below.


Background

In July 2017, the Ministry for Primary Industries (MPI) detected the bacterial infection Mycoplasma bovis in cattle at a South Canterbury dairy farm. This is the first time it has been found in New Zealand.

Mycoplasma bovis is a bacterium that causes illness in cattle, including udder infection (mastitis), abortion, pneumonia, and arthritis. MPI has assured the public that the infection cannot be passed on to humans and that it presents no food safety risk. MPI have stated that there is no concern about consuming milk and milk products from affected cattle.

Farmers should call their veterinarian if they suspect their cattle are showing any of the clinical signs of the disease. These can include:

  • Mastitis in dry and milking cows.
  • Arthritis in cows.
  • Late term abortions.
  • Premature calves.
