Hard to Tell the Good Guys From the Bad

There are thousands of different types of blue-green algae, and only a few produce harmful toxins. Tell your friends to listen to this:

Blue green algae aren’t all bad. After all, there are about 6,000 different species…

Boyer: And there are probably only a hundred or so that are known to make toxins that would be considered harmful.

That’s Greg Boyer of the SUNY College of Environmental Science and Forestry. He says the organisms are some of the oldest and most diverse on the planet. They thrive in sun, warmth, and calm waters. But add to that too many nutrients, and they can bloom out of control.

Some blooms make toxins that can be harmful if ingested, touched, or even inhaled. But others do not…the trouble is you can’t tell which is which without a toxicity test. So, play it safe… if you see an algal bloom – stay away.
