Managing diseases of animals
Pests and diseases that affect animals can have a major impact on your business's profitability, so it's important to understand the risks and take action to protect your animals.
If you notice unusual signs of disease, abnormal behaviour or unexpected deaths in your livestock, call the Emergency Animal Disease Watch Hotline on 1800 675 888. This national service operates 24 hours a day, 7 days a week.
Some diseases can be transmitted from animals to people, so it's essential to minimise this risk by practising good personal hygiene, wearing protective clothing, maintaining healthy animals and undertaking preventative treatments and vaccinations where appropriate.
This guide provides an overview of pests and diseases in animals. It also includes information about on-farm biosecurity and what you can do to minimise risk.
Protecting your farm
On-farm biosecurity involves protecting your livestock against pests, diseases and chemical residues.
Assessing the biosecurity risks and planning to control them can improve profitability of your business and contribute to your local community's economic health.
If you suspect an emergency animal disease or pest in your animals, report it to your veterinarian and the Emergency Animal Disease Hotline on 1800 675 888 immediately.
Read the Biosecurity basics: ways to prevent risk to your property fact sheet for more information.
Biosecurity risks
Introducing new livestock to your property may spread diseases, pest or weeds.
Purchase livestock from a known and reliable disease-free source and seek written assurances about their health status, including vaccinations.
Keep new or returning livestock separate and monitor them for a minimum of 14 days (may be longer if concerned about certain diseases) before introducing to other animals on your property.
Keep movement records for 2 years for horses and 5 years for cattle, sheep and goats notify NLIS database of relevant movements within 48 hours of receiving livestock.
Water and stock feeds
Disease-causing agents and weeds may be brought onto a property through water or livestock feeds. To reduce risks:
- assess water sources for diseases, chemicals or algal bloom
- obtain a vendor declaration for raw stock feeds
- do not feed prohibited feed to pigs or poultry and do not feed restricted animal matter (animal meal and fish meal) to ruminants.
Visitors, vehicles, equipment and machinery
Visitors can accidentally bring disease and pests onto your property. Visitors may include neighbours, agents, salespeople, advisers, shooters, fishers and veterinarians.
To reduce biosecurity risks from visitors:
- place a sign at the front gate advising visitors of your entry requirements
- minimise entry points for vehicles where practical
- ensure visitors and their vehicles entering your property come clean, go clean
- minimise visitor contact with animals where possible
- ensure machinery is cleaned and free of soil, faeces and weed seeds before entry onto the property
- avoid sharing equipment between properties – if equipment is borrowed or lent, clean and disinfect equipment thoroughly.
Insect vectors
Insects such as mosquitoes, ticks and biting flies can spread disease and negatively impact on animal health and welfare. To reduce risks:
- implement an integrated control program to reduce biting insect populations
- look at livestock during periods of risk (after rain when insect populations increase).
Pest and vermin, or feral animals
Pest animals such as wild birds or feral animals and vermin can introduce disease onto livestock properties. To reduce risks:
- erect external fencing that is sufficient to keep feral or wild animals out of livestock areas
- implement a feral animal management program on your property
- manage vermin where feed is kept, reducing disease transmission or potential contamination of feed sources.
Good management
All livestock owners have a duty of care under legislation to care for their animals.
A health program should include plans for adequate nutrition, and timely husbandry procedures such as vaccinations and chemical applications.
All agricultural and veterinary chemicals must be used according to label instructions. Withholding periods must be observed to avoid chemical residues in animal products.
Monitor and report
Monitor your animals for signs of disease and pests. Isolate sick livestock (where practical) and report unusual signs in livestock immediately to your veterinarian and the Emergency Animal Disease Hotline on 1800 675 888 immediately.
Dispose of carcasses appropriately.
Biosecurity management plan
If you own animals, develop a biosecurity management plan to minimise their potential for entry and impact.

Animal health
By law, all animal owners have a duty of care to look after their animals correctly.
Planning for adequate nutrition and animal care through a health program will help you prevent pests and diseases.
All veterinary chemicals must be used correctly according to label instructions and withholding periods observed to prevent chemical residues in plant or animal products.

Diseases that can spread from animals to humans
A disease that is naturally transmissible from animals to people is classified as a zoonosis.
Zoonotic diseases can spread in many ways, such as:
- working closely with infected livestock
- contact with infected pets, exhibited animals or wildlife
- contact with soil or water contaminated by animals
- consumption of contaminated unpasteurised dairy products.
Preventing the spread of animal diseases to humans
Practising good personal hygiene, wearing protective clothing, maintaining healthy animals and undertaking preventative treatments and vaccinations where appropriate can minimise the risk of some animal-borne diseases infecting people.
If you work with or handle animals you should take precautions to reduce your risk of infection.
- Keep animals healthy.
- Minimise their exposure to other animals that are likely to be infected (e.g. minimise domestic dog exposure to feral pigs that may be infected with Brucella suis. Dogs may become infected and serve as a source of infection for humans).
- Vaccinate livestock for known zoonotic diseases, such as anthrax and leptospirosis in cattle, and Hendra virus in horses.
- Ensure you and your staff are vaccinated for zoonotic diseases where a vaccine is available and you are at risk of contracting the disease, such as Q-Fever.
- Wear personal protective equipment (PPE) where possible, and cover any wounds with water-tight dressings. Protect against mosquitoes and other biting insects that can transmit diseases by:
- covering up with a loose-fitting long-sleeved shirt and long pants when outside
- applying mosquito repellent to exposed skin.
- Disinfect or wash your hands regularly – especially before eating, preparing food or smoking.
- Ensure you, your family and your staff seek medical attention if unwell. Talk to your medical practitioner about minimising the likelihood of being infected with zoonotic diseases.

Reportable animal diseases
Some animal diseases are prescribed as category 1 restricted matter or prohibited matter under the Biosecurity Act 2014 and must be reported to Biosecurity Queensland.
If animal owners, vets, laboratory staff or anyone else suspects the presence of category 1 restricted matter or prohibited matter, they must notify Biosecurity Queensland on 13 25 23 or the Emergency Disease Hotline 1800 675 888.
View the list of category 1 restricted matter and prohibited matter.
