Australian bat lyssavirus and handling bats

Australian Bat Lyssavirus (ABL) is closely related to the rabies virus. Only vaccinated people who have been trained in the care of bats should handle them. Read the Australian bat lyssavirus and handling bats fact sheet (PDF, 0.28 MB) or watch the video on safe bat handling.

Petting zoos

Contact with animals at petting zoos can spread infection to workers and visitors. Some people, such as infants and young children, are especially vulnerable to infection and serious illness can occasionally occur. Good hygiene practices, including hand washing, are important to manage infection risks. Read the managing infection risks at petting zoo guideline (PDF, 0.37 MB)

Leptospirosis (or Weils Disease) is an infectious zoonotic disease caused by bacteria and spread in the urine of infected animals (wild anddomestic) and in water and soil contaminated with infected urine. Leptospirosis is a notifiable disease.

Hydatid disease

This disease is caused by infection with a small tapeworm parasite Echinococcus granulosus. People become infected by eating eggs of this parasite, usually when there is hand-to-mouth transfer of eggs in dog faeces.


Toxoplasmosis occurs worldwide and is found in mammals, especially cats and birds. Infection in humans is common, caused by a parasite called Toxoplasmosis gondii which is usually found in cats and other mammals and birds.
