Officials with the New South Wales (NSW) Department of Primary Industries (DPI) and Local Land Services  have reported the first confirmed case of anthrax this year. The detection occurred in the Central Tablelands on a property with no previous record of anthrax. The affected animals were ewes that had not been vaccinated for anthrax.

This has prompted DPI to urge producers to vaccinate their livestock.

Biosecurity measures at the affected property, including stock movement restrictions and the vaccination of remaining livestock were immediately imposed.

DPI Senior Veterinary Officer, Dr Graham Bailey said while there are no general public health risks or trade implications from the detection it served as a timely reminder.

“Drought conditions create a favourable environment for anthrax infections so producers should consider vaccination to protect their livestock,” Dr Bailey said.

“Ingestion of soil by sheep, cattle and other ruminants is one of the key risk factors for anthrax, which is why drought conditions increase the risk.

“Cases of anthrax in NSW tend to occur in an area which runs through the centre of the state, between Bourke and Moree in the north, to Albury and Deniliquin in the south.

“Anthrax can be prevented by annual vaccination of cattle and sheep. Producers in high risk locations are encouraged to consider vaccination.”

Other risk factors include a history of anthrax on the property, grazing stubble or very short pastures, low ground cover, deep cultivation or earthworks in paddocks, soil movement or exposure as a result of rain, contact with infected carcasses and alkaline soils which favour spore survival.
