The Illinois Environmental Protection Agency and Department of Public Health are reminding residents to exercise caution if they are planning activities on Illinois waterways, including lakes, rivers, streams and ponds.
During summer months, water conditions are ideal for blue-green algae growth, which are microscopic organisms that naturally occur in lakes and streams. Rapid growth of algae is referred to as a “bloom.” While most blue-green algae are a natural part of our ecosystems and are harmless, some can produce toxic chemicals that cause sickness or other health effects in people and pets.
People who plan to recreate in or on Illinois waters this summer are advised to avoid contact with water that:
looks like spilled green or blue-green paint;
has surface scums, mats, or films;
is discolored or has green-colored streaks; or
has greenish globs suspended in the water below the surface.
People are also advised to keep children and pets out of the water. Do not allow pets to drink from the water and do not allow them to lick their fur after swimming in water containing a blue-green algae bloom. If you or your pet has contact with water you suspect may have a blue-green algae bloom, rinse off with clean, fresh water as soon as possible.
If you are concerned you have symptoms that are a result of exposure to algal toxins, contact your health care provider or call the Illinois Poison Center at 1-800-222-1222. If your pet experiences symptoms that may be a result of exposure, contact your veterinarian.
