SEATTLE — Public Health — Seattle & King County has detected toxic algae in three lakes in the county including Lake Washington, Green Lake and Lake Wilderness in Maple Valley.
The toxic algae may be impacting other lakes, ponds and streams in the county.
"At this time, the levels detected could harm pets, and some algae blooms may pose a threat to human health," Public Health said in a statement.
Public Health officials are urging pet owners to make sure their pets do not enter the water in the lakes where algae is visible. Signage is visible at Green Lake warning people of the risk toxic algae presents.
"It's definitely something where when I see the signs, I don't let my dog around the water," said Joshua Hawley walking his dog named Brutus. "When toxic algae is present, don't swim in the lake, don't let your dogs around the lake."
According to Public Health, toxic algae can produce toxins that can make both people and pets sick, and that algae can even be fatal for pets.
Even if you do not see the algae, the toxic algae can still be present, officials warn.
Pet owners should watch for numerous symptoms of possible exposure to your pet. Those symptoms include low energy, lack of appetite, vomiting, diarrhea, difficulty breathing or seizures. Symptoms typically occur within minutes to hours after exposure, according to Public Health.
If you pet becomes ill, Public Health urges you to call your veterinarian immediately.
