Cattle brucellosis, also known as contagious miscarriage, is a disease that poses a significant threat to cattle farmers and their herds, causing reproductive issues and requiring challenging treatment in humans. The disease, caused by the bacterium Brucella abortus bovis, can spread through contact with infected animals' amniotic fluid, offspring, or unpasteurized milk. It has seen a rise in recent years and is transmitted through contact with an infected animal. All female animals are required to be vaccinated against the disease, with a specific vaccination schedule to ensure effectiveness. The article also highlights the importance of maintaining herd health by ensuring vaccination records, testing negative for the disease, and preventing contact with unvaccinated or infected animals. A new policy approved by the Department of Agriculture aims to unify the disease control strategy for cattle brucellosis. For further information, contact Dr Chris van Dijk or Dr Newton Sparks.
