One obvious way to know the algae bloom may be toxic is if you see large numbers of dead fish or waterfowl, according to the Utah Department of Health. “Animals found dead may have algae around the mouth area or on the feet and legs, indicating possible ingestion of and contact with a toxic bloom,” according to the department’s website.
Is algae harmful to humans and animals?
Some algae growth is important to a healthy ecosystem. Many ani-mals eat algae and most species of algae are not dangerous. When algae grow too much or rapidly, it is called an algal bloom. However, some species of algae are toxic to humans, animals, and the environment. When these algae bloom, it is referred to as a harmful algal bloom (HAB).
What are symptoms of toxic algae?
“We don’t want to go in that direction.” Exposure to toxic algae can cause immediate symptoms, such as a runny nose, watery eyes and trouble breathing. Long-term exposure has been linked to liver disease and is suspected of causing neurological ailments years down the road.
Are all algal blooms harmful?
Red tides, blue-green algae, and cyanobacteria are examples of harmful algal blooms that can have severe impacts on human health, aquatic ecosystems, and the economy. Algal blooms can be toxic. Keep people and pets away from water that is green, scummy or smells bad.
What is a harmful algal bloom?
Harmful algal blooms are the rapid growth of algae or cyanobacteria that can cause harm to people, animals, or the local ecology. Harmful algae or cyanobacteria can look like foam, scum, paint, or mats on the surface of water and can be different colors. These blooms can produce toxins that make people and animals sick.

Why are algae important?
Algae are vitally important building blocks of the food chain and ecosystem. Algal blooms occur when there are overgrowths of algae, including green, brown, or red microalgae, or cyanobacteria that are commonly referred to as blue-green algae.
What are the effects of HBs on water?
HABs can produce toxins that are harmful to people and animals. The algae and cyanobacteria also reduce the levels of oxygen in the water when they decompose , and these lower oxygen levels may kill other plants and animals in the water.

Toxic algae blooms occur when colonies of harmful algae grow excessively, which has negative effects on people, animals and the surrounding environment. No one knows for sure what exactly causes these colonies to develop. They can occur in both freshwater and saltwater environments in nearly any aquatic system.

However, when a lake or pond’s ecosystem is out of balance, it can lead to unchecked growth of algae populations, known as blooms. Some algae blooms are known for the toxins they release into the water. If left to grow, they can have a severe impact on human health.
Why do algae bloom?
Scientists have noticed that algae blooms thrive when conditions like wind and water currents direct them together, as well as warm temperatures and extreme events like floods or hurricanes. Nutrient overloads in the surrounding water from human activity can also contribute to algae’s growth.

Report any illness associated with a harmful algal bloom to your local, state, or territorial health department. In some states and territories , this can be done through an online form or a hotline.
What to do if you get sick from algae?
If you are notified of harmful algae or cyanobacteria in a nearby body of water or in your public drinking water supply, follow local or state guidance to reduce your chances of getting sick. Check for and follow local shellfish and fish advisories before eating any fish or shellfish you collect.
What is the name of the organism that lives in water?
Algae and cyanobacteria are simple, plant-like organisms that live in the water. Algae and cyanobacteria can rapidly grow out of control, or “bloom,” when water is warm, slow-moving, and full of nutrients. Blooms can occur in fresh water, salt water, and brackish (a mixture of fresh and salt) water around the world.

What happens when blue green algae blooms?
When the bloom begins to die, it releases toxin (microsystin) if the cells contain it. Cyanobacteria are partial to warm water, so nutrient-rich lakes on warm summer days are particularly ripe for blooms.

If you see leaves or roots, or distinguishable parts, it’s likely a tiny (and harmless) aquatic plant like duckweed. Stringy, silky substances that can be draped over a stick are green algae. If it’s yellow and almost “dusty” in texture, it might act like blue-green algae, but it’s actually tree pollen.
How to tell if a bloom is toxin?
There’s no way to tell if the bloom is toxin until the water is tested. You are encouraged to tell the Lilly Center when blooms are happening so we can sample them. Follow the guide below! (And if you’re not sure if you’re seeing blue-green algae or green algae, stay out of the water.)
Why do algae grow faster?
Warm weather and plenty of sunshine (as well as increased nutrients come from a variety of sources, such as storm water runoff, and decaying algae and other organisms) are the key factors. When cyanobacteria get an advantage and are able to grow quickly, they smother other kinds of algae.
What is the difference between blue green algae and cyanobacteria?
The first is “blue-green algae” and the second is the more-proper “cyanobacteria.”. The name is a little misleading, though, because blue-green algae aren’t quite plants or algae. We call them algae because they’re free-floating and grow in colonies, but in reality, blue-green algae are a form of bacteria. Cyanobacteria are found all ...
Which side of a lake is more likely to have a bloom?
In the right circumstances, the downwind side of your lake is more likely to have a bloom. Microcystin is the most common toxin produced by cyanobacteria in our county, so that’s what the Lilly Center focuses on when sampling blue-green algae blooms. We measure microcystin in parts per billion.
What is blue green algae?
Blue-green algae is a form of bacteria, so the cells interact with water differently than true algae, almost appearing to be a part of a water. You won’t be able to identify individual cells or roots. A bloom can even seem to turn the water into “pea soup,” moving along with the water and changing its tint. Sometimes cells can clump together, but ...
