| 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. |
