KDHE and KDWP have issued several public health advisories for Kansas lakes due to blue-green algae

Sedgwick County, KANSAS – State officials said that a harmful algal bloom may look like foam, scum or paint floating on the water and be colored blue, bright green, brown or red.

Officials also said that blooms can develop rapidly; if the water appears suspicious or there is decaying algae on the shore, avoid contact and keep dogs away.

Ladies and gentlemen, you should be very careful, because these toxins can be absorbed by ingestion, inhalation of aerosols and even skin contact, state officials said..

If you, or your dog, come into contact with algae rinse the area with clean, fresh

water. Suspected HAB-related health incidents, whether human or animal, regardless of season, should be reported here.
