The Wisconsin Department of Natural Resources warns beachgoers of blue-green algae and the risks it poses.
Blue-green algae, or cyanobacteria, can have harmful effects on humans and pets if swallowed, inhaled through water droplets, or irritation if rubbed onto the skin.
The peak bloom season of the harmful blue-green algae is in July and August, when waters are the warmest.
Most rivers and lakes in the state are not treated for the algae which means it is important to stay safe with the best practices.
The DNR warns not to swim in water that looks like “pea soup”, spilled paint, or water that has a scum layer.
They also do not recommend boating or water skiing over this same type of water to avoid inhalation exposure.
Symptoms of blue-green algae toxin poisoning include vomiting and diarrhea if ingested, as well as sore throat and wheezing from inhalation.
For pets, the symptoms and recommendations are the same for humans.
They also recommend washing pets after they are in a lake or river to prevent them from licking algae on their fur.
More information on the harmful blue-green algae can be found on the DNR’s website.
