Blue Green Algae (Cyanobacteria)
Blue-green algae blooms have raised concerns in Connecticut and across the nation because these organisms can produce a wide array of neurotoxins, liver toxins, cell toxins and skin irritants. In still and warm summer waters, populations of blue green algae may increase to the extent that a normally clear surface can become thick and murky. This overgrowth is called a “bloom”. Blooms are considered harmful due to the potential to cause health effects in people and pets over-exposed to these organisms.
