​Toxic bloom reaches upper Swan

Friday 14 February 2020

Fishers need to heed the now extended toxic algal bloom warnings for the Swan and Canning rivers

​Recent disturbing social media posts by recfishers have shown some people willing to defy the health warnings not to consume shellfish (including crabs) or fish from the Perth's rivers.

Fishers who do are putting themselves at serious risk, if they consume anything they've caught in the Swan and Canning rivers' algal bloom warning areas. 

The latest advice from the Department of Health reminds us that  ingestion of toxins produced by the microscopic Alexandrium species of algae can produce a type of poisoning known as paralytic shellfish poisoning (PSP). Cooking does not destroy these toxins.
