Algal bloom update

​Whilst there has been a decline of the Alexandrium algal bloom in the Swan and Canning Rivers recently, the Department of Health warning from 22 February not to eat shellfish, crabs or fish from designated areas within those river systems is still in place. View map

 
Please do not consume fish, shellfish or crustaceans caught in the affected areas until the all-clear is given as ingestion of seafood containing these toxins can produce a type of poisoning known as paralytic shellfish poisoning, which is not destroyed by cooking.
 
For more details, see the Department of Health warning or detailed FAQs on the Alexandrium algal bloom and paralytic shellfish poisoning.
