Levels of the toxin microcystin have been detected in Lake Erie weeks earlier than usual, according to the National Oceanic and Atmospheric Administration.

Levels of the toxin microcystin have been detected in Lake Erie weeks earlier than usual, according to the National Oceanic and Atmospheric Administration.

Microcystin is a group of toxins produced by cyanobacteria, or blue-green algae, according to the U.S. Environmental Protection Agency. They are the most common cyanobacterial toxins and can be found inside algal cells. They can also accumulate in common marine life, such as zooplankton, mussels, and fish.


At certain levels, microcystin toxins produced by certain types of freshwater blue-green algae can pose health risks to people and pets, NOAA said in a release on Friday. They primarily affect the liver but can impact the kidneys and reproductive systems as well, according to the EPA.

The presence of microcystin may also prompt additional treatment at public drinking water systems, according to NOAA.
