Brucellosis and cattle: what people should know

People who handle cattle, assist with births, clean animal areas or process meat may contact blood, placenta, urine, milk or other materials that carry bacteria. Drinking raw milk or eating products made from it is another possible route. The bacteria can enter through broken skin, the eyes, the mouth or inhalation.

Human brucellosis may present with fever, night sweats, tiredness, muscle aches and joint pain. A cattle exposure does not confirm infection, and symptoms can be mild or develop gradually.

After a significant exposure, wash exposed skin, change contaminated clothing and tell a healthcare professional exactly what happened. Do not consume unpasteurised milk from a suspect animal. A blood test may be part of the assessment, with timing and follow-up decided clinically.

If infection is confirmed, prescribed antibiotic treatment is needed. Avoid sharing leftover antibiotics or stopping early because symptoms have eased. People who work with cattle should follow local veterinary and workplace protective measures.

Arrange prompt assessment for persistent fever, sweats, fatigue or unexplained aches after handling cattle or consuming raw dairy. Go to urgent care for confusion, severe weakness, breathing difficulty, fainting or inability to keep fluids down.

Ask whether the exposure needs testing, which symptoms to monitor, whether repeat testing is needed, how treatment interacts with other medicines, and what protective equipment is appropriate for future cattle work.
