2nd Mycoplasma bovis case found in New Zealand

New Zealand officials confirm they have a second case of mycoplasma bovis infecting a dairy cow.  Reuters reports the case was found on New Zealand’s South Island and was detected in early July.

Both cases happened in close proximity, and at large dairies operated by the Van Leeuwen dairy group.  Steps have been taken to restrict movement of cattle at the site, and testing will continue on all Van Leeuwen farms as well as neighboring farms.

The bacterial infection can cause acute mycoplasma mastitis, and cause reproductive problems, lameness, respiratory disease, arthritis, and pneumonia.  Animal researchers at Purdue University say the disease is highly contagious and therapy resistant.  New Zealand officials confirm that some animals have been voluntarily euthanized.  Dr. Chris Rodwell said Friday the disease is under control with restrictions placed on 16 properties.

Reuters says analysts are concerned about possible market reactions, and how it might impact New Zealand’s dairy export business.  New Zealand’s Primary Industries Ministry says the infection can be passed to other cows through milk, but it does not infect humans or present food safety risks.
