With summer approaching, it’s important to be aware of blue-green algae, also known as cyanobacteria, which can appear in lakes, rivers, and ponds across Nova Scotia. These blooms can produce toxins that pose serious health risks to people, pets, and wildlife if ingested or contacted.
Blue-green algae often look like green scum or paint on the surface of the water, and may have a musty or grassy smell. Swimming, drinking, or even coming into contact with affected water can lead to symptoms such as skin irritation, nausea, or more serious health effects. Children and pets are especially at risk.
Nova Scotians are encouraged to report suspected blooms and avoid contact with affected water. Pay close attention to public advisories and signage when visiting natural water bodies.
