In FRDC 2007/007 and FRDC 2009/044, it was determined that ornamental fish entering Australia are a source of exotic pathogens, such as cyprinid herpesvirus 2 (CyHV2). This is of particular relevance for goldfish, where domestic breeders claim that their stock succumb to CyHV2 disease when brought into contact with imported goldfish in wholesale and retail premises. CyHV2 only affects goldfish and was addressed in the 1999 IRA as being exotic to Australia. Recent research findings from FRDC 2009/044 indicated that CyHV2 is present in domestic Australian goldfish populations. On 1 September 2011, Biosecurity Australia amended the health certification requirements for the importation of goldfish and no longer requires fish to be certified free of CyHV2.
The detection of CyHV2 and other exotic aquatic pathogens (e.g. gourami iridovirus) was achieved through the application of molecular techniques, such as PCR. Correctly applied and interpreted, molecular approaches offer unique opportunities to understand the local and global spread of a disease. The advancement of molecular approaches is required to safeguard Australia against pathogen incursions through the processes of informed policy development and import risk analysis.
There is a need to disseminate the research that determined that CyHV2 is now established in Australia and how scientific evidence was used to change national biosecurity policy to the international scientific community. There is also a need to ensure the availability of people with specialised training in molecular epidemiology in Australia to stay at the forefront of the application of this technology.
