The naturally occurring algal bloom, Alexandrium tamarense, continues to affect Tasmania's east coast between Eddystone Point and Marion Bay.
Commercial shellfish harvesting has resumed in most growing areas on the east coast, but remains subject to intensive monitoring and closures apply where necessary.
Water quality is tested regularly and the latest results show Alexandrium tamarense cell counts continue to fluctuate but remain at low levels.
Tests are conducted for the presence of paralytic shellfish toxins and strict protocols are in place to prevent shellfish with unsafe PST levels reaching the market.
Seafood bought from retail outlets is safe to consume.
