Livestock health & diseases

Western Australia’s freedom from many pests and diseases allows our livestock producers access to a wide range of international and domestic markets. To maintain this enviable biosecurity status, the Department of Primary Industries and Regional Development ensures significant livestock disease is investigated. This information helps to assure trading partners that we are free of diseases.

Some diseases can have devastating effects on the livelihoods of everyone in the supply chain. To ensure the impacts on the economy and community are minimised, the department maintains trained, response-ready staff and systems to ensure an emergency animal disease incident is promptly and efficiently controlled. In addition, the risk of introduction of exotic disease is also managed by ensuring stockfeed contains appropriate ingredients.
