(TNS) —Kansas health officials say there are 15 bodies of water you should avoid swimming in over Labor Day weekend.

The lakes have harmful algae blooms that can kill pets that drink or swim in the water, state officials said.

Boating and fishing may be safe at lakes under a public health warning for blue-green algae, Kansas Department of Health and Environment and Kansas Department of Wildlife, Parks and Tourism officials said in news releases. But direct contact with the water -- including wading, skiing and swimming -- is strongly discouraged for people, pets and livestock.

"Dogs can become seriously ill or die if they swim in, drink or retrieve a bird from water affected by a (harmful algae bloom)," state wildlife officials said. "They can even be sickened if they lick their fur after exposure or eat dried algae along the shore or floating in the water."

A harmful algae bloom may look like a foam, scum or paint floating on the water and have a strong musty odor or smell of sewage or petroleum, KDWPT officials said. A bloom can be blue, bright green, brown or red. Blooms may float around the water.

Health officials say you can eat only the fillet portion of fish as long as you rinse the fish with clean water.

Signs of illness from blue-green algae in a dog are vomiting, diarrhea, lethargy, convulsions, difficulty breathing and general weakness, state officials said. Symptoms in humans include rashes, vomiting, diarrhea, fever, sore throat and headaches. It is recommended that you immediately rinse with clean water any area that comes in contact with algae and call your physician or veterinarian if you or your dog show signs of illness.
