Additional cases of blue-green algae have been confirmed in two more areas on Lake Nipissing.

A statement Wednesday from the North Bay Parry Sound District Health Unit says a harmful algae bloom, or cyanobacteria, has been found in Campbell’s Bay in Patterson Township and Simpson’s Bay in Nipissing Township.

The algae species, which are capable of producing toxins, were confirmed at a Ministry of the Environment, Conservation and Parks laboratory.

The health unit warns that the toxins may cause skin irritation, as well as diarrhea and vomiting if swallowed.

Due to the difficulty in determining when and where there are no toxins present, users of either one of the bays are advised to exercise their judgment.

The latest announcement comes nearly a week after the health unit confirmed the detection of blue-green algae at Marathon Beach in North Bay and Centennial Park Beach in Callander.

The health unit is advising those near where a bloom has been detected or is visible to not use the water, including for drinking, cooking, bathing and brushing teeth.

Using a private water system or boiling the water will not destroy the toxins.

The public also is advised to not swim, and avoid water sports, where a bloom is present.

If skin contact occurs, wash with soap and rise thoroughly with clean water to remove the cyanobacteria.

Other safety measures include eating a limited amount of fish and shellfish, and to avoid eating the liver, kidneys, and other organs. Care should be taken when filleting a fish in order to not cut the organs.
