Sheep producers are advised to understand anthrax and be watching their sheep closely for symptoms after cases on four properties in the Swan Hill area in early 2017.
Anthrax is an infectious bacterial disease caused by the spore-forming bacteria Bacillus anthracis.
This bacterium is zoonotic meaning that it can be transmitted to humans. You would need to handle a deceased animal and breathe in spores to contract, therefore people are advised to report any unexplained sudden deaths.
BCG livestock systems researcher Alison Frischke said to be prepared and aware of the disease, but don’t be alarmed.
“Anthrax is something to be aware of, but don’t be alarmed. The most important thing is to report any symptoms or unexpected deaths and be vigilant if, or when, handling the carcasses.”
Anthrax spores live in the soil and can survive for decades before infecting animals that graze on the contaminated land.
The disease is most commonly found along old stock routes across Australia, but is not limited to these areas. Outbreaks often occur in the summer time when animals are grazing pasture close to the soil.
The most common sign of Anthrax is a sudden and/or unusual death of livestock. Because the disease acts so quickly, it is unlikely that you will be able to see any obvious signs on a live animal.
However possible signs of Anthrax include; just prior to death, the animal may show signs of a high fever and there also may be some a dark discharge from the mouth, nose and anus on the carcass of the animal. These signs however should not be relied on for accurate diagnosis of Anthrax.
The 24-hour Emergency Animal Disease Watch hotline (1800 675 888), your local veterinarian or Agricultura Victoria animal health staff are the people you need to contact if you suspect any issues on your property.
