Molesworth Farm Achieves TB-Free Status

Molesworth Farm, a well-known dairy farm in the South Island of New Zealand, has achieved a significant milestone in its ongoing efforts to eradicate bovine tuberculosis (TB). This achievement is not only a testament to the farm’s commitment to animal health but also a major step towards meeting export market requirements.
According to Molesworth Farm manager, Leslie, the farm’s journey to TB-free status has been a long and challenging one. “It’s a great recognition,” he said. “Lots of hard work to get to where they’ve got to.”
Leslie highlighted that achieving TB-free status is not only important for animal health but also for the export market.

“A TB-free status is not only important for animal health but also export market requirements,”

he stated. This is because many countries have strict regulations when it comes to importing and exporting livestock products, and bovine TB is a major concern for these countries.
Molesworth Farm has been home to several significant research projects on the reduction and elimination of bovine TB.

• The farm has been involved in several studies on the most effective methods of reducing TB in herds.
• Researchers have also explored new approaches to detecting and eliminating TB in livestock.
• The farm has also been involved in monitoring and controlling the spread of TB in the wider community.

To achieve TB-free status, Molesworth Farm implemented a comprehensive livestock testing programme, which involved reducing the numbers of infected animals through on-farm skin and blood testing.

In addition to the livestock testing programme, Molesworth Farm also implemented large-scale possum control on-farm. Possums are considered one of the main spreaders of bovine TB. The farm’s efforts to control possum populations have been instrumental in reducing the risk of TB transmission. Leslie also paid tribute to his colleague, Jim Ward, who has been on-farm for over half the period of infection. “Jim has been a key driver of this status outcome, but of course, it’s been a collaborative effort,” he stated. “The credit for this tremendous success goes to all the people and organisations who have worked for a very long time to make this TB result a reality.”
The TB-free status achieved by Molesworth Farm is a significant step along the path to TB freedom. As OSPRI chief executive, Sam McIvor, noted, “This is a staged process, and this is a significant step along the way.” However, the farm’s journey to TB freedom is not yet complete, and “we still have some ongoing surveillance work to confirm that TB is finally gone.”
As of April 1, there are 12 infected herds across the country.
