IDEM Cylindrospermopsin Reports

What is Cylindrospermopsin?

Cylindrospermopsin is a toxin produced by cyanobacteria including Aphanizomenon, Lyngbya and Raphidiopsis.  It has been found in freshwater throughout the world including some lakes in Indiana.  Testing for cylindrospermopsin begins in July because species that produce it generally appear later in the summer. Most of the cyanobacterial cells that produce it are regarded as subtropical/tropical species. Cylindrospermopsin is a hepatotoxin that primarily affects liver and kidney function.
