Anthrax is an acute infectious disease affecting sheep, cattle, horses and pigs, and many other animals including humans. Cases occur occasionally in New South Wales, but they tend to be confined to an anthrax 'belt', which runs through the centre of the state and into Victoria.

The disease is unpredictable. It can recur more than 50 years after its apparent disappearance in an area, so it is essential that all stock owners remain aware of the disease.

Vaccination is highly effective, and reduces the long-term risk to stock and humans.
