The Sudbury and District Health Unit and the Ministry of the Environment and Climate Change are investigating a possible blue-green algal bloom at Kalmo Beach on Whitson Lake in Greater Sudbury.
In a news release, the health unit said the MOECC is testing water samples to confirm the presence of blue-green algae.
“As a precaution, the health unit has posted signs advising the public to avoid swimming, drinking the water, and allowing pets into the water if the algal bloom is present at the beach,” the release said.
“If no bloom is present, water can be used for regular recreational activities.”
Greater Sudbury is working with the health unit and the MOECC to monitor the situation, the release said.
“Blue-green algae could also appear in other parts of the lake,” they said. “Because blooms are not anchored, they can move from one location to another through wind and water action. New blooms can also form. All residents on lakes or rivers should look for blooms in their area.”
Blue-green algal blooms have an unsightly pea soup appearance and foul smell, and can produce toxins.
The highest concentrations of toxins are usually found in blooms and scum on the shoreline, the release said.
“These dense accumulations pose the greatest potential risks to people and pets,” the release said.
“The algae toxins can irritate a person’s skin and, if ingested, cause diarrhea and vomiting. If a person ingests high levels of toxin, they could suffer liver and nervous system damage.”
