Plain-English definition
Real-world example

Definition of Zoonotic Disease

An infectious illness that can be transmitted between animals and humans through direct contact, bites or scratches, contaminated materials, airborne particles, or insect vectors. Workers in agriculture, veterinary medicine, animal research, meat and poultry processing, and wildlife management face elevated occupational exposure risk.

Example of Zoonotic Disease

A poultry farm adopts biosecurity measures — including respirators, eye protection, and dedicated coveralls — for workers handling birds during an avian influenza outbreak to reduce the risk of zoonotic transmission.

Frequently Asked Questions: Zoonotic Disease

What are common occupational zoonotic diseases?

‍Examples include brucellosis, Q fever, leptospirosis, psittacosis, rabies, avian influenza, and tick-borne illnesses such as Lyme disease, with risk depending on the animals and environments involved.

How can employers reduce zoonotic disease risk?

‍Common controls include handwashing and hygiene facilities, appropriate PPE, animal health monitoring, safe handling and restraint practices, pest and vector control, and, where available, vaccination for high-risk roles.

Should workers report animal bites or illness after animal contact?

‍Yes, prompt reporting allows medical evaluation and, for exposures like potential rabies, timely treatment that can be critical; it also helps employers identify and address gaps in controls.
