Fifth farm tests positive for prawn virus

Prawns at a fifth Queensland farm have been destroyed after they tested positive for an exotic virus new to Australia.

Biosecurity officials have been monitoring farmed and wild prawns in southeast Queensland after white spot disease was detected in the Logan River area, south of Brisbane, last month.

Four infected prawn farms close to the river and each other were initially destocked, but a fifth one - about four kilometres downstream - tested positive a few days ago.

"At this stage it is not yet clear how the virus has come to be present on this premises," Biosecurity Queensland has said in a statement.

"There are three other aquaculture premises in the immediate vicinity, but one of these currently has no prawn stock."

Testing continues to determine the spread of the virus, which has severely affected farmed prawn production overseas.

It has already been found in wild prawns in the Logan River.

Prawns caught in Moreton Bay, off Brisbane, and in the Brisbane River, are also being screened for the virus, which is not harmful to humans but can cause high mortality rates, especially in farmed prawns.
