DEEP begins warning of potential toxic algae blooms in state lakes and waterways

Oregon Health Authority issues warnings on toxic cyanobacteria blooms in waterways

Cyanobacteria (often called “blue-green algae”) can form blooms in still or slow-moving water. When conditions are right…warm temps, stagnant water, and nutrient runoff, these blooms can release toxins into the air and water. ⚠️ Why does this matter? •Airborne exposure (the sneaky one) → when blooms die or get agitated (wind, boats, sprinklers, waves), they can release aerosols and tiny toxin-containing particles into the air. •For someone with a primed innate immune system (like CIRS), even sma
