Animal health and diseases

Notifiable diseases in animals and how to report them

There are more than 100 diseases of livestock and animals classified as notifiable diseases in the Northern Territory (NT).

They are declared under the Livestock Act 2008 and are classified in one of 3 categories:

  • exotic diseases - not present in Australia (such as BVDV type 2)
  • emergency diseases - usually not present in Australia, but if detected, may have a nationally cost-shared response and compensation under the Emergency Animal Disease Response Agreement (EADRA) - read more on the Animal Health Australia website
  • endemic diseases - currently exist in Australia, which can cause significant economic losses to industry or with the potential to infect people (zoonosis), such as Hendra virus in horses.

NT veterinary officers and livestock biosecurity officers are trained to investigate and respond to outbreaks of emergency animal diseases.

To find out more about protecting industry from animal disease, go to the Department of Industry, Tourism and Trade website.

You should also read the responding to emergency animal diseases fact sheet.

How to report

If you’re an animal owner, property manager, livestock agent or veterinarian, you must notify the chief veterinary officer (CVO) if you suspect or know an animal that has a notifiable disease. This ensures these diseases are controlled in the event they are detected.

Emergency diseases must be reported within 24 hours. There is a penalty for failing to report a notifiable disease.

If you suspect or confirm an emergency or exotic bee or animal disease, call the 24-hour animal biosecurity hotline on 1800 675 888 or your local veterinary or livestock biosecurity officer.

More information

To find out more about emergency animal diseases, go to the Animal Health Australia website.


African swine fever

Help protect Australia

African swine fever (ASF) has been confirmed in countries close to Australia including Timor Leste.

Travellers, pig owners and hunters should follow the advice below.

ASF is a contagious disease of pigs. It doesn't affect human health.

An ASF outbreak in Australia would have a serious impact on the pork and agriculture industries.

ASF spreads easily by direct contact between affected pigs or by exposure to contaminated items including:

  • feed
  • feed ingredients
  • equipment
  • vehicles
  • clothing and footwear.

It can also be spread through meat from infected animals.

The virus survives under most environmental conditions and is resistant to most disinfectants. It is not inactivated by freezing or heat less than 100 degrees celsius.

The most likely way ASF can enter Australia is through international travel and mail.

Declare goods when entering Australia

You must declare certain food, animal products and plant material when arriving in Australia.

If you don't declare goods that may risk Australia’s biosecurity, you could be fined or prosecuted.

Check your mail

Don't order animal or food products containing meat from overseas though the mail.

You must make a report if you receive international mail that contains meat or animal products. Do this on the Australian Government's Department of Agriculture website.

More information

To find out more read the following:

You can also get posters on:

You should take precautions to keep Australia free from ASF.

Don't feed swill to pigs

Food that contains meat or meat products, or that has had contact with meat or meat products, is known as swill.

It is illegal to feed swill to pigs.

You can feed your pigs:

  • commercially prepared pig feeds
  • grains
  • fruit and vegetables that have not had contact with meat
  • Australian milk and by-products.

To find out more read the Agnote on prohibited pig feed PDF (160.8 KB).

Get a property identification code

You must register a property identification code (PIC) if you own pigs.

It is free to get a PIC and can be done online.

The PIC system allows animals to be easily traced if an animal disease outbreak takes place.

Failure to register a PIC can incur penalties.

Check for signs of disease

You should report any signs of disease immediately by calling the Emergency Animal Disease Hotline on 1800 675 888.

Symptoms of ASF include:

  • sudden death
  • high fever and loss of appetite
  • lethargy
  • skin reddening
  • blueness of extremities (including ears)
  • bloody diarrhoea
  • vomiting
  • abortions.

Find your nearest government vet.

Complete a waybill if your pigs move

If you plan to move your pigs, you must complete an NT waybill.

This is an official record of livestock movement, which will allow a biosecurity response team to track animals in the event of an outbreak.

Protect your pigs from disease

You can minimise biosecurity threats by taking simple measures to protect the health of your pigs and restrict the spread of an outbreak.

Find resources to help keep your farm and pigs clean on the farm biosecurity website.

Cattle tick control

Cattle tick is a serious pest in the Northern Territory (NT). It affects cattle, buffalo, horses, mules, donkeys, sheep, goats, camels, deer, llamas and alpacas.

It can reduce your livestock production and also spread tick fever, which causes sickness and death in affected animals.

Read the Agnote cattle ticks PDF (258.5 KB).

Controlling the spread of cattle tick

The NT has a control program which aims to contain ticks to within specific zones, and lower the risk of spreading to areas which aren't yet infected.

It includes measures against the spread of Parkhurst cattle tick, which is a strain resistant to commonly-used chemical treatments.

Interstate and NT stock movements are controlled to limit the risk of ticks spreading.

NT cattle tick areas

Get the map of NT cattle tick areas PDF (1.1 MB).

Parkhurst cattle tick

The Parkhurst cattle tick is resistant to certain chemical products such as Bayticol, Barricade S, Blockade S and Tixafly.

It was first detected on cattle stations in the Darwin region in the late 1990s and has now spread to many properties in the area.

For more information read the acaricide resistant cattle tick fact sheet.

Acaricide resistant cattle tick fact sheet PDF (175.2 KB)
Acaricide resistant cattle tick fact sheet DOCX (896.9 KB)

In 2011 a Parkhurst Infected Zone was introduced to contain the Parkhurst cattle tick from Darwin to Pine Creek and east to the boundary of Kakadu National Park.

If you want to move stock out of this zone you must have them inspected and treated. Horses can be moved from the zone to the Cattle Tick Infected Zone without being inspected or treated.

Controls on stock movement

There are different levels of control on stock movement depending on which zone cattle are leaving and where they are going.

The following stock are affected by these controls:

  • cattle
  • buffalo
  • bison
  • banteng
  • horses
  • sheep
  • goats
  • camels
  • deer
  • llamas
  • alpacas.

National Johne's disease program

Johne's disease is a serious bacterial wasting disease in cattle, sheep, goats, alpaca, llama, camels and deer. There is no known treatment.

It is not known to exist in the Northern Territory (NT) and has only been detected when infected animals have been brought in from interstate.

If you are a cattle producer you will need to make a biosecurity plan to help stop the disease spreading to the NT.

You will also need to follow the rules for moving livestock. Some of these changed on 1 July 2017.

A property biosecurity plan can help reduce the risk of disease entering or spreading from your property.

To find out more about making a farm biosecurity plan, go to the Animal Health Australia website. You can also get a biosecurity action list.

You do not need to lodge the plan with anyone. You should keep your plan and any related documents on hand for future reference.

If you don't make a plan

If you don't make a biosecurity plan you might not be able to trade with some properties or markets.

You won't be able to sell or move cattle into Western Australia (WA).

This is because your property will be scored at a higher risk of disease under the Johne's Beef Assurance Score (J-BAS) system.

J-BAS

The J-BAS is a number from 0 to 8 which represents the risk of Johne's disease on a property.

A high score means a low risk of Johne's disease.

Your NT property will go from J-BAS 7 to J-BAS 0 if you don't have a biosecurity plan.

If you want to sell or move cattle into WA you will need at least a J-BAS 7.

Live export markets require a property to be free from Johne's disease for up to five years. This is consistent with J-BAS 6.

You should check your markets and find out if your buyers require a J-BAS.

Get a J-BAS

Find out how to get a J-BAS using the J-BAS flowchart for NT producers PDF (839.3 KB).

Read what you need to do when moving and exporting livestock.

For information about moving cattle, buffalo, sheep, goats, deer or camelids get the Johne's disease: livestock movement requirements fact sheet PDF (819.0 KB).

Bring cattle into the NT

Cattle and buffalo entering the NT must be:

  • free from Johne's disease with a NT health certificate and waybill
  • certified as having a herd score of J-BAS 6 or higher for beef cattle and buffalo or a dairy score of 7 or higher for dairy cattle and dairy buffalo
  • accompanied by a National Cattle Health Declaration
  • identified with a three-hole punch if vaccinated with Silirum vaccine.

If you need to test for Johne's disease as part of J-BAS you should ask your veterinarian for testing options.

Get the Johne's disease: information for NT veterinarians fact sheet PDF (828.7 KB).

If your cattle test positive for Johne's disease

If your cattle test positive for Johne's disease, you must report it to the chief veterinary officer. If initial results are positive, more testing will need to be done.

More information

For more information and resources to help reduce the risk of Johne's disease, go to the Animal Health Australia website.


Ehrlichiosis disease in dogs

Help protect Territory dogs

Ehrlichiosis has been confirmed in the Northern Territory (NT).

All dog owners should follow the advice below.

Ehrlichiosis is a disease spread by the brown dog tick. It primarily affects dogs. It can result in death if not properly treated.

In very rare cases, infected ticks may infect people. Infections in people are usually easy to treat. To date, there have not been any cases of ehrlichiosis diagnosed in people in the NT.

Dog owners should have their dogs on a tick control program, regularly check their dogs for ticks and be on the lookout for signs of the disease.

How it is spread

Dogs become infected with the bacteria Ehrlichia canis after being bitten by an infected brown dog tick. The brown dog tick is widely distributed worldwide and is present in northern Australia, including all of the NT.

Ehrlichiosis is now established in the NT brown dog tick population, and all dogs are at risk of infection.

Infected dogs do not transmit ehrlichiosis to people. In very rare cases, infected ticks may infect people.

Read more about the human health impacts of ticks on the Government of Western Australia's Department of Health website.

Symptoms

Symptoms of ehrlichiosis infection in dogs can include:

  • fever
  • lethargy
  • loss of appetite
  • weight loss
  • swelling of chest or front legs
  • cloudy eyes or conjunctivitis
  • pain and stiffness
  • bleeding disorders such as nosebleeds or bruising on the gums or belly.

How to protect your dog

The following will protect your dogs from ehrlichiosis.

  • Have your dogs on a tick control program. Tick collars and spot-ons that repel and kill ticks are the best primary protection. These can be used in combination with tablets and chews registered for tick control in high risk situations. Speak to your vet about the best products for your dog.
  • Have any tick infestations in your house or yard managed by a pest controller.
  • Avoid taking your dogs into tick-infested areas. If this is unavoidable, use effective tick control products and inspect your dogs daily for ticks. Run your fingers through your pet’s coat over their skin, feeling for abnormal bumps. Pay particular attention to the head, neck, ears, chest, between their toes and around their mouths and gums.
  • Contact your vet if you find ticks on your dog and are concerned about the risk of ehrlichiosis. Brown dog ticks do not bury their heads under the skin and can be safely pulled off when you find them.
  • Be on the lookout for signs of ehrlichiosis, such as fever, lethargy and appetite loss.

When to see a vet

You must seek veterinary attention immediately if your pet is showing signs of ehrlichiosis, such as fever, lethargy and weight loss.

Other tick-borne diseases such as anaplasmosis and babesiosis have similar symptoms to ehrlichiosis. These diseases are also present in the NT so it is important to seek veterinary advice and treatment.

If you find a tick on your dog, contact your vet for tick control treatment options.

Protecting your dog in the community

If your dog has contact with other dogs in your community, such as through kennels or dog groups, you should make sure that vaccinations and tick, flea and worm treatments are up to date.

Boarding your dog

Check that your your local boarding kennel have strong disease prevention measures in place to prevent movement of ticks between kennels and dogs.

Dogs with known or suspected infectious diseases should not be boarded. Use tick control products that kill and repel ticks for all dogs in boarding kennels.

Travelling with dogs

Travelling with dogs can increase exposure to many infectious diseases.

Avoid contact with other dogs when making stops along your journey, such as at fuel stations, truck stops or caravan parks. This will help to avoid ehrlichiosis transmission between dogs by the brown dog tick.

If your dog gets sick when travelling, tell your veterinarian where you went and when.

Social group dog activities

Participating in social group dog activities can also increase exposure to many infectious diseases.

Vaccinate your dog according to your vet’s directions before participating in social activities with other dogs or attending public spaces where dogs mingle. Always use an effective tick repellent product on your dog to prevent ticks attaching.

Inspect dogs for ticks after being in potentially tick-infested areas (especially around the neck, head, ears, armpits and belly) and carefully remove any ticks. Your vet can advise on the best methods of tick removal.

Adopting or purchasing a dog

If you are adopting or purchasing a new dog, ask if it has been tested for ehrlichiosis.

Rehoming organisations should provide advice about:

  • the dog’s history
  • where it has come from
  • if it has been tested or treated for ehrlichiosis or not.

Ask your vet for advice about the risks of adopting dogs that have, or have had ehrlichiosis.

A bite from a single tick is enough to transmit the disease.

Puppies and adult dogs are equally at risk of infection.

Treatment

If your dog has been diagnosed with ehrlichiosis, it is important you follow the treatment plan recommended by your vet.

This includes completing the course of antibiotics prescribed. Early antibiotic treatment provides the best chance of recovery.

In some cases very sick dogs may need supportive care and hospitalisation.

Don't move your dog

Don’t move your dog away from your town or community until it is recovered and it’s treatment is finished.

Treat your home and yard

Controlling ticks in your environment is important to break the transmission cycle of the disease. Speak with a professional pest controller about treating your home.

Ticks can live in cracks and crevices around your house and yard, around kennels, and inside skirting boards, window and door frames. They can survive for many months without feeding.

Report the disease

If you suspect your dog is showing signs of the disease, you should report it to your local veterinarian and seek testing and treatment as quickly as possible.

Dogs that are treated soon after infection usually have better outcomes.

Zoonoses - animal diseases that can affect humans

Diseases passed from animals to humans are known as zoonoses (pronounced zoo-oh-no-sees).

They can be caused by viruses, bacteria, parasites and fungi.

Zoonoses can be passed by livestock, pets, feral animals and wildlife. They can infect you through direct contact or indirectly through contaminated water, soil or equipment.

Types in the NT

Zoonoses that may occur in the Northern Territory (NT) include all of the following:

  • Australian bat lyssavirus
  • cat-scratch disease
  • cryptosporidiosis
  • giardiasis
  • Hendra virus
  • hydatids
  • leptospirosis
  • listeriosis
  • melioidosis
  • psittacosis
  • Q Fever
  • ringworm
  • salmonellosis
  • scrub typhus
  • sparganosis
  • toxoplasmosis.

For information about specific diseases, go to the NT Health website.

Prevention

For information about preventing zoonoses, go to the Australian Veterinary Association website.

The site also has a comprehensive list of zoonotic diseases in Australia.


Hendra virus in horses

If you own horses, or move them from interstate into the Northern Territory (NT), you should know about the risk of Hendra virus.

Hendra virus is spread by flying foxes and bats. It causes respiratory or neurological disease in horses. In some cases it can be passed on to humans. Read more about flying foxes.

There are no known cases in the NT, however, the virus is carried by flying foxes in the Territory.

Most of the known cases in Australia have been in Queensland.

Information for horse owners and the horse industry

For more information read the following:

To access a Hendra virus infection resource kit, go to the Queensland Government's Department of Health website.

The Queensland Department of Agriculture and Fisheries has extensive resources and information about Hendra virus. To find out more about Hendra virus for industry and horse owners, go to the Queensland Government's Business website.

Japanese encephalitis in animals

Japanese encephalitis (JE) is a mosquito-borne viral disease that mostly occurs in pigs and horses.

It can cause:

  • reproductive losses and neurological disease in pigs
  • encephalitis (a rare but serious infection of the brain) in horses.

In rare cases, it can cause disease in other animals and people.

JE is not spread directly from pigs to people. Read more about JE in people.

Watch the latest update and find out more below.

JE has been detected in more than 50 feral pigs across the Top End including:

  • Victoria Daly, Litchfield, Tiwi Islands and West Arnhem local government areas
  • Marrakai-Douglas Daly and Cox-Daly unincorporated areas.

Surveillance activity continues across the NT.

Other states or territories

In February 2022, JE was detected in Australian piggeries in Victoria, New South Wales and Queensland.

In March 2022, cases were also detected in South Australia.

Read more about JE interstate on the Australian Government’s Department of Agriculture, Fisheries and Forestry website.

In March 2022, JE was declared a communicable disease incident of national significance.

Notifiable diseases are those that:

  • pose a threat to livestock production industries or public health
  • could have a major impact on international trade.

Suspected cases of notifiable diseases must be reported.

Food safety

JE is not a food safety concern and pork products are safe to eat.

The NT does not have any commercial piggeries. However, pig owners, hunters and landowners should report signs of the disease.

It is not known how the virus has come into Australia. The movement of infected mosquitoes or migratory waterbirds may have played a part in the virus’ spread.

Movement restrictions have been applied to infected pig properties in Australia.

Life cycle

Animals and people become infected with the virus through the bite of infected mosquitoes.

The normal lifecycle of JE is between waterbirds and mosquitoes, which may then accidentally spill over to pigs and horses.

The spread from pig to pig through genetic material such as semen is rare.

Horses are known to be a ‘dead end host’. They do not carry a blood infection that will reinfect mosquitoes.

You should monitor your pigs and horses for signs of JE.

Pigs

  • Mummified and stillborn or weak piglets, some with neurological signs.
  • Boars may experience infertility, fluid retention (oedematous) and congested testicles.

Horses

In many cases, horses can be infected but not show signs of the disease. Most clinical disease is mild. However, more severe encephalitis can occur which may be fatal.

Signs include:

  • elevated temperature
  • jaundice
  • lethargy
  • anorexia
  • neurological signs such as:
    • incoordination
    • difficulty swallowing
    • impaired vision
    • over-excitement.

To find out more about signs, go to the Australian Government's Department of Agriculture, Fisheries and Forestry website.

If you're a pig owner with a property identification code (PIC), you can get your registered pigs tested for free.

To arrange testing, contact your local vet or livestock biosecurity officer.

Read more about the testing process PDF (388.5 KB).

There are steps you can take to reduce the impact of the disease.

This includes making sure that any stagnant water does not become a breeding ground for mosquitoes.

How to protect pigs

If you work with or have contact with pigs, you should:

  • take steps to control mosquitoes
  • continue to use effective biosecurity measures.

How to protect horses

If you own horses, there are steps you can take to protect them from mosquito bites.

  • During hotter months, cover your horse with:
    • a light cotton rug
    • a fly mask and
    • a safe insect repellent if the horse allows. Don't spray it around or above the eyes.
  • Stable horses between dusk and dawn.
  • Horses left outside overnight can wear a lightweight permethrin (insect repellent) fabric.

To find out more, read the JE AUSVETPLAN response strategy on the Animal Health Australia website.

How to protect yourself

Find out how to protect yourself against mosquitoes and how JE affects people.

Management

Surveillance and testing are underway in the NT, and you must follow instructions given by biosecurity authorities.

If you notice anything unusual or suspicious, you must report it.

It is important to maintain good biosecurity practices on your property. This includes having a property identification code (PIC) for your animals.

Get more advice on the Farm Biosecurity website.

Lumpy skin disease

Lumpy skin disease (LSD) is a serious disease of cattle, water buffalo and banteng. It is spread by biting flies and mosquitoes, midges and possibly ticks.

It has never been detected in Australia but is an emerging threat as it continues to spread throughout Asia.

LSD is highly infectious and caused by a virus like sheep or goat pox from the poxviridae family. It causes cattle, water buffalo and banteng to develop widespread skin lumps, scabs and ulcers.

It does not affect other livestock or humans.

Responsibilities

Enhanced surveillance for LSD is underway in the NT. You can help by remaining alert for LSD.

Read the information below to find out what you should do.

One way LSD can enter Australia is through international travel and mail.

Declare your goods

You must declare certain food, animal products and plant material when arriving in Australia.

If you don't declare goods that may risk Australia’s biosecurity, you could be fined or prosecuted.

Read more about international travel and your responsibilities on the Australian Government website.

Check your mail

Don't order animal hides, or animal or food products containing meat from overseas through the mail.

You must make a report if you receive international mail that contains meat or animal products. Do this on the Australian Government's Department of Agriculture website.

Check for signs

If you see any signs of LSD in your livestock, you should report it immediately.

You must:

Get a property identification code

You must register a property identification code (PIC) if you own cattle or buffalo. It is free and can be done online.

The PIC system allows animals to be easily traced if an animal disease outbreak takes place.

Complete a waybill if you move livestock

If you plan to move your cattle or buffalo, you must complete an NT waybill.

This is an official record of livestock movement which allows a biosecurity response team to track animals if an outbreak happens.

How to protect your livestock

To reduce the impact of insect-borne diseases on your animals, make sure any stagnant water does not become a breeding ground for mosquitoes or other biting insects.

To find out more about protecting the health of your livestock and reduce biosecurity threats, go to the Farm Biosecurity website.

LSD can look like other common skin diseases such as:

  • bovine herpes virus 2
  • warts
  • mange
  • ringworm
  • rain scald.

Brahman (bos indicus) cattle and buffalo have more subtle skin lumps compared with the British breed (bos taurus) cattle. This may make detection of LSD harder in northern Australia where breeding Brahman cattle is more common.

You should consider LSD as a differential diagnosis in livestock that have multiple skin lesions.

As LSD can only be diagnosed at a laboratory, you should take samples and submit them for diagnostic testing.

You can get case subsidies and free testing at the Berrimah Veterinary Laboratory.

Always practise good biosecurity when you are out hunting.

  • Clean and disinfect all equipment on site.
  • Report any unusual signs in animals by calling the emergency animal disease hotline on 1800 675 888.
  • Respect all quarantines and restrictions that are in place.
  • Don't move live animals to new locations.

Where it is found

LSD is established in Africa, the Middle East, south-east Europe, Turkey, Kazakhstan and Russia.

In the past few years, it has been reported in:

  • Bangladesh, China and India in 2019
  • Taiwan, Nepal, Vietnam, Bhutan, Hong Kong and Myanmar in 2020
  • Thailand and Malaysia in 2021
  • Indonesia in 2022.

The disease has never been recorded in the Northern Territory (NT) or Australia but is spreading rapidly internationally.

Symptoms

Cattle, water buffalo and banteng infected with LSD will have the following symptoms:

  • fever
  • depression
  • tiredness
  • skin nodules:
    • 2 to 5cm, round, firm and slightly raised
    • found on the head, neck, limbs, udder and under the tail area
    • may become scabby, ulcerated and infected
    • can cause severe pain and inflammation.

Animals may go off their feed and some may die.

Any cases of skin lumps and scabs should be investigated thoroughly by a vet to rule out LSD.

Impact

If LSD was found in Australia, it would impact cattle and buffalo livestock industries and trade.

The Australian Veterinary Emergency Plan (AUSVETPLAN) would be used to guide the emergency response to the disease.

You can find out more on the Animal Health Australia website.

Lifecycle and spread

Cattle, buffalo and banteng can become infected with the virus through the bite of infected insects, including flies, mosquitoes, midges and possibly ticks.

The virus can also remain active on infected animals, and can contaminate by-products like hides, as well as equipment and other surfaces.

Experts are studying all the ways the LSD can be spread to understand more about the disease.

Prevention

Eradication of LSD is difficult and early detection would be essential for successful control.

The Australian Government has put measures in place to stop LSD entering Australia. Read more on the DAFF website.

The NT has a plan to keep the region free from the disease. Read the NT LSD action plan PDF (295.9 KB).

Vaccination

There is currently no LSD vaccine approved for use in Australia.

In southern Europe, vaccination has been used to effectively control LSD outbreaks. However, in other areas, vaccination has not been successful.

Testing

If you're a vet or producer who wants to test cattle for LSD, follow these steps:

Step 1. Read the sample test kit fact sheet PDF (463.8 KB).

Step 2. Request a sample kit by filling in the livestock skin disease and sample kit form DOCX (60.9 KB).

Get the sample kit guide PDF (627.9 KB) to find out what's in the kit.

Step 3. Take the skin sample.

You can also watch a demonstration of livestock skin sampling below.

Swine brucellosis

Swine brucellosis is an infection caused by the bacteria Brucella suis (B. suis).

While B. suis usually affects pigs, it can cause serious illness in people. It can be potentially fatal.

Infection with B. suis is a notifiable disease, and must be reported to the chief veterinary officer.

B. suis affects pigs, cattle, horses, dogs and humans.

To find out more read below. You can also get a printable B. suis information sheet PDF (702.9 KB).

B. suis has been detected in feral pigs in the Northern Territory (NT).

It's widespread in Queensland's feral pig population, and has also been detected in the feral pig population in northern New South Wales.

Other species of the Brucella bacteria can cause different types of brucellosis.

Australia is free of Brucella abortus, Brucella melitensis and Brucella canis.

Bovine brucellosis is caused by Brucella abortus and was eradicated from Australia in 1989 as a result of a national eradication program.

Control of B. suis in feral pigs isn't possible, and treatment of domestic pigs is not considered practical.

Treatment for infected dogs includes a long course of antibiotic therapy and desexing to reduce the risk of spread to people or other animals. Treatment is not always successful, and in some cases dogs will relapse.

Humans are treated with extended courses of antibiotics.

You should monitor for the following signs.

Pigs

Pigs will general show signs of:

  • reproductive failure
  • piglet mortality
  • swollen testicles.

Dogs

Dogs can remain bright, alert and show no obvious signs of infection.

Clinical signs include:

  • fever
  • swollen testicles
  • back pain
  • lameness
  • vomiting
  • lethargy
  • haematuria
  • abortion.

Cattle and horses

Cattle and horses may pick up infection from open waters used by feral pigs.

There are no specific clinical signs associated with B. suis infection.

However, both cattle and horses may react positively to brucellosis testing due to infection with B. suis.

A positive test result for brucella in cattle during a herd fertility test, must be investigated to ensure that it has not been caused by brucella abortus (bovine brucellosis), which is exotic to Australia.

Humans

The incubation period in people is variable from 5 days to months, but averages 2 weeks.

Weakness, fatigue and exhaustion are common with fever, head and body pains and mental depression.

Anyone who suspects they may have been infected with B. suis should contact their doctor.

Recovery can take up to 12 months, but antibiotics shorten the disease course.

Spread

The main source of infection is infected pigs.

Boars can pass the disease on during mating. Spread can also occur by the ingestion of food and water contaminated with:

  • urine
  • placenta
  • discharges from infected sows.

The organism can survive in faeces, urine and water for 4 to 6 weeks and much longer in freezing conditions.

Direct sunlight will kill the organism quickly.

Dogs

Infected dogs are a potential source of infection for people through contact with urine, saliva and reproductive materials.

Dogs may also act as mechanical carriers by shedding Brucella in the faeces after ingesting infected aborted foetuses or placentas.

Humans

In humans, B. suis mainly affects:

  • abattoir workers
  • pig farmers
  • feral pig shooters.

Humans can contract the disease through skin, conjunctiva and by ingestion.

Killing and slaughter of feral pigs can increase the risk of human infection unless strict hygiene measures are taken.

Infection can occur from contaminated meat during preparation, cooking and serving of feral pig meat.

Veterinarians can submit:

  • whole blood or serum for serology
  • fresh, chilled tissue
    • eg. entire testicle, uterus or aborted foetuses for bacterial culture.
    • note: can't differentiate between specific species of Brucella. 

Tissue specimens should not be sliced open as this may increase the risk of human infection.

Label clearly 'Brucella exclusion'.

All samples are double bagged and any paperwork is outside the sample container.

Prevent the entry of feral or other infected pigs onto your property.

If you notice reproductive disease or swollen testicles in your pigs, contact a veterinarian.

When handling pigs you should:

  • cover all cuts and abrasions with waterproof dressings
  • wear enclosed waterproof footwear
  • use good personal hygiene
  • wash your hands regularly.

Safe handling practices

Use personal protective equipment (PPE) including gloves and eye protection when:

  • handling pregnant or sick pigs
  • butchering pigs.

When hunting:

  • cover all cuts and abrasions with waterproof dressings
  • wear enclosed waterproof footwear
  • use good personal hygiene
  • wash your hands regularly.

Clean and disinfect work areas and vehicles after a hunt.

If butchering feral pigs take extra precautions including wearing gloves and eye protection. If a pig looks sick, don't handle or butcher it.

Always cook game meat thoroughly.

Don't feed raw feral pig meat to your dogs.

When handling pigs and pig hunting dogs you should use good personal hygiene and wear:

  • PPE
  • including gloves and eye protection.

Particular care should be taken when:

  • treating wounds
  • collecting blood
  • neutering
  • assisting with whelping or reproductive problems
  • performing caesareans on pig hunting dogs.

A safe work method statement for collecting samples for B suis testing is available from the NSW Department of Industry website.

Foot-and-mouth disease in animals

Foot-and-mouth disease (FMD) is a highly contagious viral infection of cloven-hooved animals (the hooves are divided into 2 parts).

This includes cattle, buffalo, pigs, goats, sheep and deer.

An outbreak of FMD in Australia could have devastating consequences for livestock industries and the wider community.

It is not a threat to human health or related to human hand, food and mouth disease. It can't be passed on to people through meat.

FMD is caused by a picornavirus. Worldwide, there are 7 distinct serotypes of FMD virus: O, A, C, SAT 1, SAT 2, SAT 3 and Asia 1.

Responsibilities

Read the information below to find out what you should do.

Never bring any meat or animal products back into Australia if you’ve been travelling overseas.

If you have been hiking, or visiting farms or rural areas overseas you must declare this on entry to Australia.

Clothing and equipment such as hiking gear that has been in contact with animals, animal waste or soil must be carefully cleaned and disinfected.  This is because the virus can survive in particles of soil.

Carrying infectious virus on the soles of shoes, walking sticks etc, could lead to infection of animals in Australia.

If you may have been in contact with FMD-infected animals, you should not visit any property with livestock for at least 7 days after returning to Australia.

Learn to recognise the signs of FMD and monitor your animals closely.

You should prevent:

  • visitors from having unnecessary contact with your livestock
  • contact between domestic and feral pigs.

Check for signs

You must call the emergency animal disease (EAD) hotline immediately on 1800 675 888 if you have any young animals:

  • that die suddenly or
  • you suspect one of your animals may have blisters (formed or ruptured).

Get a property identification code

You must register a property identification code (PIC). It is free and can be done online.

The PIC system allows animals to be easily traced if an animal disease outbreak takes place.

Complete a waybill if you move livestock

If you plan to move livestock, you must complete an NT waybill.

This is an official record of livestock movement which allows a biosecurity response team to track animals if an outbreak happens.

Feeding pigs

Only feed fruit, vegetables, grains and commercial livestock feed to pigs.

Never feed prohibited feed (swill) such as kitchen scraps to pigs as it can introduce FMD and other serious animal diseases.

Keep pigs out of dumps.

Property biosecurity plan

Have a property biosecurity plan in place. Make sure all workers and visitors are aware of your biosecurity rules.

This may include not allowing anyone who has been overseas to come onto your property for 7 days after arriving back into Australia.

Practise good hygiene

Ensure items and equipment coming on to or leaving your property are clean.

Wear clean clothes and footwear when visiting a property

Always practise good biosecurity when you're out hunting by:

  • cleaning and disinfecting all clothing, equipment and vehicles on site
  • reporting any unusual signs in animals by calling the emergency animal disease hotline on 1800 675 888
  • respecting all quarantines and restrictions that are in place
  • not moving live animals to new locations
  • taking your rubbish home – food scraps may be eaten by animals, which is a potential form of swill feeding.

Signs

The disease can look slightly different in different species. In all species, very young animals may die.

  • Lethargic and reluctant to walk
  • Drooling
  • Blisters or ruptured blisters:
    • in the mouth and on the tongue
    • on the teats of females
    • between the toes and around the top of the hoof
  • Rapid weight loss
  • Signs in buffalo might not be as severe.

  • Lameness - pigs may appear to want to crawl instead of walk due to painful hooves.
  • Blisters on the feet or blanched (white) looking skin around the hoof.
    • In severe cases the hoof may appear to be detaching from the toes.
  • Blisters on the snout.

  • Signs of FMD in sheep and goats are usually very mild and may be easily missed.
  • Common signs can include a fever and lameness in one or more legs.
  • Blisters may form in the mouth but are not as noticeable as in cattle.

Where it's found

FMD is found in the Middle East, African, Asian and South America.

It has not occurred in Australia since 1872.

In May 2022, an outbreak of FMD was reported in cattle in Indonesia.

International outbreaks are a reminder that animal diseases can spread quickly and do not respect international borders.

How it's spread

FMD is one of the most contagious animal diseases.

Infected animals excrete the virus in fluid from:

  • ruptured blisters
  • exhaled air
  • saliva
  • milk
  • semen
  • faeces
  • urine.

Virus transmission

Virus transmission can begin before blisters appear. Some animals can carry the virus for long periods (months or years) after apparent recovery.

The primary method of transmission within herds and flocks is by direct contact or via respiratory particles and droplets.

Pigs are known to produce a lot of the virus when infected, and are a high risk of spreading FMD to other animals.

Infection can spread between properties due to movement of infected animals or contaminated vehicles, equipment, people and products.

Windborne spread of infected aerosols can occur under the right conditions.

FMD virus may remain infective in the environment for several weeks to months in organic matter such as:

  • soil
  • manure
  • dried animal secretions
  • straw
  • hair
  • leather.

FMD virus can also survive in meat and dairy products.

The most likely way FMD could enter Australia is via the illegal importation of contaminated products from overseas.

Monitoring and action

Suspect cases of FMD must be immediately investigated by a veterinarian or livestock biosecurity officer.

Where appropriate, samples of vesicular (blister) fluid, epithelial tags and blood should be collected and sent to the Berrimah Veterinary Laboratory for diagnostic purposes.

FMD is considered one of Australia's greatest biosecurity risks.

An FMD incursion would have severe consequences for Australia's animal health and trade, including considerable economic losses with restrictions being placed on both domestic and international markets.

Even an isolated, rapidly controlled outbreak could cost several billion dollars to eradicate, with serious economic and social effects in other sectors, including tourism.

Impacts would be felt across the live animal export trade, and by exporters of genetic materials, meat and dairy products.

A large multi-state FMD incident could cost Australia more than $52 billion in lost revenue over 10 years.

FMD is a viral disease that spreads rapidly between animals.

The virus is excreted in breath, saliva, mucus, milk and faeces.

Animals can become infected through direct contact with:

  • infected animals or materials
  • eating or drinking infected products
  • breathing in the virus.

The disease spreads most commonly through the movement of infected animals.

Pigs can be infected with FMD through swill feeding. This is when pigs are fed uncooked meat or unprocessed dairy products, including those that might have been illegally imported from FMD-affected countries.

Swill feeding is illegal in Australia.

Pigs produce large amounts of infectious virus in the breath, so they can infect many other animals.

Cattle are very susceptible to, and able to be infected by breathing in small quantities of the virus.

FMD-infected feral pigs could be a major source of disease for NT pastoral properties. They can shed the virus around water points and other places where cattle encounter pigs and pig waste products.

If FMD was detected in Australia, the disease would be contained and eradicated as quickly as possible in order to reinstate Australia's disease-free status for trade purposes.

The eradication program will be delivered according to the AUSVETPLAN response strategy for FMD.

Measures to eradicate the FMD outbreak would include:

  • strict movement controls, including an immediate livestock standstill
  • tracing the movements of animals, animal products, people and things to identify where infection has spread
  • surveillance to detect infected herds and flocks
  • the humane slaughter and biosecure disposal of infected herds and flocks
  • decontamination to destroy the virus
  • other movement controls and enhanced biosecurity to minimise spread of disease.

Emergency livestock vaccination may, in certain circumstances, be an important part of controlling an FMD outbreak.

Australia will consider the potential for emergency vaccination of livestock as part of the response strategy from the day an incursion of FMD is detected.
