Swan and Canning River warning

Public Notice 21 December 2020

The Department of Health is reminding us not to eat shellfish including mussels, oysters, clams, pipis, scallops, cockles and razor clams from the Swan and Canning Rivers because of possible infection from microbial, heavy metal and other contaminants.

We’re also being advised to ensure blue swimmer crabs caught in the rivers are cleaned thoroughly, removing the head, guts and gills before freezing, cooking or eating.

The warning is due to the detection of the toxic algae Alexandrium in the Swan River in the past few days. The organism can produce Paralytic Shellfish Toxins and can be dangerous if eaten.

Signs have been installed in areas around the river. For more information contact the Department of Health on 9222 2000 or visit the Department of Primary Industries and Regional Development (DPIRD) or the Department of Biodiversity, Conservation and Attractions (DBCA).
