Where are cyanotoxins found?

Cyanotoxins are toxins produced by cyanobacteria (also known as blue-green algae). Cyanobacteria are found almost everywhere, but particularly in lakes and in the ocean where, under high concentration of phosphorus conditions, they reproduce exponentially to form blooms.

What states have Bluegreen algae?

In addition to the cases above, blue-green algae has been confirmed in Ohio, Maryland, Massachusetts, New Jersey, New York, South Carolina, Rhode Island, California, Florida, and Minnesota. Unconfirmed cases have also been reported as far north as Maine.

Where is blue-green algae commonly found?

Are cyanotoxins harmful to humans?

Cyanotoxins can cause gastrointestinal, neural, hepatic, or dermal toxicity. The time to onset of GI symptoms after oral exposure is usually 3–5 hours and symptoms can last 1–2 days. Exposure can cause conjunctivitis, rhinitis, earache, sore throat, and swollen lips.

Is it OK to drink algae water?

Drinking algae-affected water or consuming food (such as fish or shellfish) containing toxins can lead to gastroenteritis, which can induce vomiting, diarrhoea, fevers and headaches. These toxins may also affect the liver or nervous system. Pets and livestock can also be affected by harmful algae.

What happens if you touch blue-green algae?

Exposure to high levels of blue-green algae and their toxins can cause diarrhea, nausea or vomiting; skin, eye or throat irritation; and allergic reactions or breathing difficulties.

Is it safe to swim in algae lake?

Do not fish, swim, boat, or play water sports in areas where there is harmful algae or cyanobacteria. 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.

How can you tell if blue-green algae is present?

If the algae have formed a green ring at the top of the water, there is a strong possibility that your lake does have a blue- green algae community. If your lake or pond has a mat of green material floating on the surface, the stick test can help determine what it is.

Does blue-green algae affect humans?

Blue-green algae blooms are harmful when they produce toxins that can make humans and animals sick. Most blooms are not harmful.
