Monitoring within the Hawkesbury River has found a harmful algae species, Alexandrium pacificum. The algae was found in the waters of the lower reaches of the Hawkesbury River, downstream of the Pacific Highway bridge, with the highest concentrations at Porto Bay.
The algal bloom has not been detected in the upper areas of the estuary.
This algae can accumulate within shellfish and can be toxic to humans when eaten. As a precaution, please do not consume any shellfish caught within this area at this time. Commercial shellfish harvest in the area has ceased and current product in the marketplace is not affected.
Monitoring of the Lower Hawkesbury will continue, and further advice will be provided as results are available.
