White spot disease detected in southern Queensland

White spot disease

White spot disease is a highly contagious viral infection that affects crustaceans. 

The disease has been confirmed in seven prawn farms. The seven infected premises are located on the Logan River. This latest detection confirms that all prawn farms in the region with stock are now infected with the white spot disease virus. 

Biosecurity Queensland is treating affected ponds with chlorine and is preparing for decontamination and disposal work. This is expected to take a number of months. 

Following the positive test results from wild caught prawns near the mouth of the Logan River in early February no further confirmed positive test results have been received, but more samples are in the process of being tested. Surveillance and sampling in all prawn farms and waterways in the region will continue. 

A Movement control order (PDF, 1.6MB), a Prevention and Control Program (PDF, 1.6MB) and a Surveillance Program (PDF, 1001.5KB) are in place to help manage the disease.

White spot disease does not pose a risk to food safety or people's health.
