Q: What does cyanobacteria look like?
Phillip Elden: Sometimes, you may never see cyanobacteria. When it blooms, it can stay below the surface and be hidden by dark water. In clear water, cyanobacteria might look like red, light green, or blue dye hovering on the water’s surface. Sometimes, you can smell cyanobacteria rotting as the blooms die, and its odor is described much like the sweet scent of rotting plants.
Q: Is blue-green algae dangerous to humans and animals?
Phillip Elden: Yes. They are considered a harmful algal bloom, and can affect people and animals in many ways. First, cyanobacteria bloom is dangerous for fish. It steals oxygen, nutrients, and sunlight. When ingested, the cyanotoxins can cause severe gastrointestinal issues.
Q: How can I prevent coming into contact with cyanobacteria?
Phillip Elden: Avoid going into bodies of water, such as lakes or reservoirs, that do not have a natural water flow. If you can’t see your feet, it’s probably best to steer clear of the water. Further, avoid boating or jet skiing in any area where there is a layer of foam on the water’s surface. Most importantly, don’t drink water that does not come from a tap or bottle.
Q: What should I do if I swim in contaminated water?
Phillip Elden: Take a shower. The best way to reduce skin contact is to wash yourself with soap and water and put on dry, clean clothing. The same is true for dogs and cats. Your animals should be washed immediately. Keep in mind that dogs should always be kept away from contaminated water as they will drink any water available if they are thirsty.
