Veterinary Public Health, Epidemiology and Zoonoses
Veterinary Public Health, Epidemiology and Zoonoses
This domain tests food safety, meat and milk hygiene, zoonotic disease control, and epidemiological measures used in animal populations.
Core rules
- Zoonoses transmit between animals and humans by direct contact, food, vectors, or environment.
- Milk safety requires pasteurisation or boiling; meat inspection detects gross lesions and residues.
- Epidemiology measures include incidence, prevalence, attack rate, relative risk, and odds ratio.
- Outbreak investigation: confirm diagnosis, define cases, describe time-place-person, form hypotheses, and control.
- Vaccination, biosecurity, quarantine, and test-and-slaughter are control tools.
Worked example
A dairy reports abortions and human cases of undulant fever. Reasoning: Brucella abortus is a likely zoonosis. Use serology and culture with biosafety. Control by test-and-slaughter, pasteurisation, and protective clothing. Notify public health authorities.
Traps
- Assuming every animal infection is zoonotic.
- Confusing incidence with prevalence.
- Drinking raw milk as a perceived health practice.
- Ignoring occupational exposure of farmers and veterinarians.
Exam focus
Name the transmission route, control measure, and surveillance data needed.
