The import of any prawns, parts of prawns or polychaete worms must be compliant with import requirements under the Biosecurity and Agriculture Management Act 2007.
Prawns with WSD may have a loose shell with numerous white spots (0.5-2.0 mm in diameter) on the inside surface of the shell and a pink to red discolouration.
A widespread outbreak of WSD would have a significant impact on the Australian aquaculture industry as well as trade implications and environmental and social impacts.
In prawn farm operations WSD can result in 100% mortality within a few days of the onset of visible signs of the disease.
WSD could pose a serious threat to WA’s freshwater and marine crustaceans in both farmed and wild fisheries including crabs, lobster and marron.
This disease does not pose a threat to human health or food safety.
What you can do
Recreational fishers are encouraged to check their bait for signs of WSD.
If you think you have found or seen WSD:
- Photograph it – from different angles and the bag the prawns were purchased in.
- Record it – make a note of when and where you purchased the prawns including the producer’s name, the trade or common name of the prawns and where the prawns came from.
- Collect it – keep the whole bag of prawns and refrigerate or freeze it and do not use it as bait.
- Report it – contact the FishWatch 24 hour hotline on 1800 815 507.
