Warning Over Burn Piles and Livestock Safety

Victorian farmers are being urged to take extra care if planning to light burn piles once fire restrictions ease, amid concerns about risks to livestock.

Agriculture Victoria is reminding farmers that contaminated ash and debris—particularly from treated timber—can pose a serious threat if stock gain access to burn sites.

Veterinary officer Dr Lydia Nicholson says a recent case near Wangaratta highlights the risks, after several cattle died displaying severe neurological symptoms including staggering, blindness and collapse.

Investigations found the animals had accessed a burn pile containing treated pine posts, commonly preserved with copper chrome arsenate.

Dr Nicholson says the chemical contains arsenic, which becomes significantly more toxic when burnt and can remain in ash that is palatable to livestock.

She is also warning farmers about the dangers of burning garden waste, with plants such as oleander and foxglove capable of causing sudden death if consumed by stock.

Producers are advised to carefully manage burn sites, restrict livestock access and seek veterinary advice if poisoning is suspected.
