Where a HAB is present, avoid coming into contact with lake water as much as possible. Rinse fish with potable water prior to cleaning. Discard entrails and other body parts, and consume only the fillet portion. There have been some studies indicating that consumption of fish from lakes with high toxin levels should be limited, even if the consumption is of fillet only. In the case where a lake is posted as "Closed," fishing should not be allowed on the waterbody.
