Blue-green algaeblooms have an unsightly pea soup appearance and foul smell. Residents should avoid using or drinking water from areas where blooms are visible, the health unit said.

The highest concentrations of toxins are usually found in blooms and scum on the shoreline, and these dense accumulations pose the greatest potential risks to people and pets,the health unit said.

The algae toxins can irritate a person's skin and, if ingested, cause diarrhea and vomiting. If a person ingests high levels of toxins, they could suffer liver and nervous system damage.
