In reply to the Hon. T.A. FRANKS ().3 June 2025).

The Hon. C.M. SCRIVEN (Minister for Primary Industries and Regional Development, Minister for Forest Industries): I am advised:

That gill and liver tissue samples from six white sharks collected within Gulf St Vincent and Investigator Strait showed low concentrations of brevetoxin groups 2 and 3. The concentrations ranged from 0.005 to 0.110 milligrams per kilogram.

That samples from oysters from closed area showed levels well above the Food Standards Code limits.

Results received for oysters samples taken 25 May 2025:

Port Vincent total brevetoxins 2.30 milligrams per kilogram.

Stansbury total brevetoxins 3.60 milligrams per kilogram.

Coobowie total brevetoxins 5.40 milligrams per kilogram.

American River total brevetoxins 2.50 milligrams per kilogram.

PIRSA are aware abalone producers have undertaken brevetoxin testing with the results remaining the property of the producer.
