Dogs are usually exposed to the toxins by drinking the HAB-affected water. However, they may still be exposed if they walk on, roll in or eat decaying algae along the shore or retrieve a bird with algae on its feathers.
The signs of illness in dogs usually occur within 30 minutes of exposure and include vomiting, diarrhea, lethargy, convulsions, difficulty breathing and general weakness. If your dog has ingested algae, or has any of these signs after exposure, contact your veterinarian immediately as HAB poisoning can quickly lead to death.
People may also become ill after contact with algae-produced toxins. Symptoms vary, depending upon the type of exposure (e.g. direct contact, ingestion, inhalation) but can include rash, vomiting, diarrhea, fever, sore throat and headache. If you, or your dog, come into contact with algae, rinse the area with clean, fresh water.
The Kansas Department of Health and Environment (KDHE) samples publicly-accessible bodies of water for cyanobacteria when the agency is alerted to a potential HAB. When a HAB occurs, KDHE, in cooperation with the Kansas Department of Wildlife, Parks and Tourism and other lake managers where appropriate, responds by informing the public of these conditions. KDHE does not sample private bodies of water such as farm ponds or livestock watering tanks.
