Description Consumption of fish containing blue-green algae toxins represents a poorly-studied, but potentially important, exposure route for humans. Microcystins and anatoxin-a are toxins of particular concern.

The Washington State Department of Ecology conducted a screening survey to assess the presence of microcystins and anatoxin-a in muscle and liver tissue from fish in six Western Washington lakes that had blue-green blooms in 2008. Microcystins were detected in all samples, with higher concentrations in liver than muscle. Anatoxin-a was not detected.

Follow-up study is recommended to obtain higher quality microcystin data that can be used to better assess the human health risk. Anatoxin-a may be too unstable to accumulate or is simply not taken up by fish.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
