Worked Solution & Example Answer:Further avian influenza outbreaks in Indonesia Avian influenza has been found closer to Australian shores, with more outbreaks in Indonesia - HSC - SSCE Biology - Question 19 - 2004 - Paper 1
Step 1
Describe at least two quarantine measures
Answer
-
Import Restrictions: Australia enforces strict import restrictions on poultry and related products from countries where avian influenza is prevalent. This preventive measure helps ensure that infected materials do not enter the country.
-
Biosecurity Protocols: Implementing biosecurity measures, such as monitoring and restricting movements of people and vehicles near farms, helps minimize the risk of virus spread from potentially infected areas.
Step 2
Explain how they assist in protecting Australia
Answer
Import restrictions directly reduce the likelihood of introducing the virus into Australian wildlife and domestic poultry populations. Biosecurity protocols mitigate transmission risks within the country by controlling contamination from external sources, maintaining the health of local birds and farms.
Step 3
Make judgements about the effectiveness of the measures
Answer
These quarantine measures have proven effective in reducing the incidence of avian influenza in Australia. The continuous surveillance and enforcement of regulations present a strong protective framework. However, the ever-evolving nature of viruses necessitates constant adjustments to these measures to ensure their ongoing effectiveness and to respond adequately to any new outbreaks in surrounding regions.
