Prawn white spot disease: What is it?

White spot disease (WSD) found in Queensland prawns is highly contagious, lethal to crustaceans and has reduced prawn farm productivity by up to 40 per cent overseas.

The Queensland Government has now confirmed that the virus has spread into the wild prawns in Moreton Bay, off Brisbane.

Beginning in November last year, seven prawn farms on the Logan River, between Brisbane and the Gold Coast in south-east Queensland, have tested positive to the devastating virus and have effectively shut down.

Queensland's chief biosecurity officer Jim Thompson said it was the first time the viral infection, which kills prawns but is harmless to humans, had reared its head in Australia.

"Australia has been the only major prawn-growing country that has not had white spot disease," he said.

Department testing results obtained by ABC Rural in January showed 70 per cent of the prawns being imported contained WSD.
