If you are planning to beat the heat at a local beach, be aware of an advisory issued by the North Bay Parry Sound District Health Unit.

“The Health Unit is advising the public that a harmful algae bloom (cyanobacteria), also known as blue-green algae, has been found in Lake Nipissing (Marathon Beach in North Bay and Centennial Park Beach Callander). Species of the algae capable of producing toxins were confirmed by the laboratory of the Ministry of Environment, Conservation and Parks. The toxins in harmful algae can irritate the skin and, if swallowed, cause diarrhea and vomiting.

“Residents of North Bay and Callander may be affected depending on their closeness to the algae bloom, the size of the lake, wind direction, water flow, and other environmental conditions that cannot be predicted or controlled. Due to the many factors involved, government authorities are unable to determine where and when there are no toxins. Users are advised to exercise their judgment.”

For further details on the location of the algae bloom, and sampling process, contact the Ministry of the Environment, Conservation and Parks – Spills Action Centre – 1-800-268-6060.

  • If you live near where the bloom was detected or where a bloom is visible, follow these safety measures:
  • Do not use the water. This includes drinking, cooking, bathing, and brushing teeth. Note: Using a private water system or boiling the water will not destroy the toxins.
  • Do not swim and avoid water sports where a bloom is present.
  • If skin contact does occur, wash with soap and water then rinse thoroughly with clean water to remove algae.
  • Limit the amount of fish flesh you eat. Some toxins can build up in fish and shellfish. Do not eat the liver, kidneys and other organs. Be careful not to cut the organs when filleting.
