Biotoxin Management

Many shellfish are subject to absorption of biotoxins which are released during algal blooms. Abalone are slow absorbers of biotoxins and there has been little concern until recent times. However an algal bloom in 2019 caused the closure of many East Coast blocks as a precautionary measure and a more rigorous monitoring process is now underway. The majority of abalone harvested are exported and as such we need to ensure the flesh is free of biotoxins. This is achieved through a Biotoxin Management Plan, which guides local authorities in their response to the presence of biotoxins in abalone.

The current document has been revised and is awaiting Commonwealth approval.
