What is Brucella suis?

Brucellosis is caused by Brucella bacteria. This page concerns Brucella suis associated with feral pigs and pig-hunting exposure in Australia. NSW Health distinguishes it from other Brucella types and identifies pig-hunting dogs and dogs fed raw feral-pig meat among the animals in which infection has been detected.

Keep the organism and location attached to the information. An account of another form of brucellosis or an overseas dog population does not establish the same situation for an Australian pig dog. Likewise, a hunting label alone is not a diagnosis of infection in an individual animal.

How the hunting and feeding history affects assessment

NSW DPIRD links canine cases with pig hunting, close contact with hunting dogs and raw feral-pig meat. Business Queensland also identifies infection in dogs from eating raw pig meat. A dog that no longer hunts can still have a relevant previous exposure history.

Prepare dates and locations of outings, known contact with pigs or other hunting dogs, feeding history and any previous test documents. Tell the veterinarian before examination or procedures so the practice can consider the exposure and appropriate precautions. For a newly acquired dog, ask the previous keeper for the history rather than assuming the present home describes its past activities.

A dog can appear healthy while infected

DPIRD says infected dogs may remain bright and alert without obvious signs. Its disease information also describes possible reproductive problems, back pain, lameness and swollen joints. These signs are not a diagnosis on their own and should not be used as a checklist that clears a dog when absent.

Contact a veterinarian about a concerning history or illness and describe both. Keep observations precise: when a change began, what was seen and which dog was affected. A statement that the dog still works enthusiastically does not answer the infection question.

Why a test result needs context

DPIRD explains that there is no single definitive blood-screening test for B. suis. Diagnosis considers the dog’s history, clinical findings and laboratory results, and inconclusive results can require further investigation. The departmental procedure effective 2 March 2026 also places investigation and interpretation within the veterinary and biosecurity process. Let the treating veterinarian determine the appropriate tests and interpretation.

When reviewing a document, retain its date, the identified animal, laboratory and conclusion. Ask what the result means for the current exposure and any proposed activity. Avoid turning an old result or a seller’s shorthand into a permanent clear status. Breeding, introducing or rehoming a dog with a concerning history needs an individual veterinary discussion.

Raw feral-pig material and post-hunt hygiene

NSW Health advises against feeding dogs raw feral-pig meat, bones or reproductive tissues. It also says freezing, smoking, drying and pickling do not kill the bacteria responsible for brucellosis. Frozen material should therefore not be assumed free of this hazard.

The hunting fact sheet addresses protective equipment, cleaning contaminated vehicles and gear, and washing dogs after the hunt, preferably before leaving the site and away from others. Plan the clean return with the landholder and veterinarian where necessary. A cleaning routine supports prevention; it cannot establish the infection status of a dog that has already been exposed.

Human exposure needs its own healthcare advice

NSW Health identifies contact with infected tissues and body fluids, including material from pigs or dogs, as a route of human infection. It also identifies pregnancy as a setting with greater risk of severe disease. Protecting people is part of managing an animal-health concern, not a separate issue to leave until someone becomes ill.

If a person becomes unwell after relevant contact, seek medical care and tell the doctor about the pigs, dogs and timing. NSW Health describes flu-like illness among possible presentations. A veterinary test for the dog does not replace a person’s medical assessment; the doctor or public-health service should advise on that person’s exposure.

Animal notification and public-health enquiries are separate

NSW DPIRD states that suspected B. suis infection in a dog must be notified within one working day. Its listed routes include the Emergency Animal Disease Hotline, 1800 675 888, or a Local Land Services veterinarian. Discuss the suspicion promptly rather than waiting for a general article to establish a diagnosis.

Queensland publishes its own animal reporting requirements through Biosecurity Queensland or the Emergency Animal Disease Hotline. Keep the jurisdiction explicit. In NSW, human exposure enquiries can also be directed to the Public Health Unit through 1300 066 055. Reporting an animal concern does not replace contacting the appropriate clinician for the dog or an exposed person.

What to record for an ongoing management plan

Keep exposure details, veterinary communications, actual laboratory reports and instructions together with the individual dog’s identity. Ask the veterinarian about other animals in contact with it, household precautions and any restrictions relevant to breeding or movement. Do not breed from a dog suspected or known to be infected, as NSW Health advises.

Clinical treatment and any later reassessment belong with the treating professionals. This page does not supply an antibiotic schedule, a test timetable or a declaration that a dog is safe to breed or rehome. Its purpose is to make the exposure history and official referral pathways easier to understand and use.
