Continue to use caution when recreating and be aware of blue-green algae
SPRINGFIELD –(ENEWSPF)—July 3, 2018
By: Rosemary Piser
Illinois officials had been alerted in June 2018 to a possible algal bloom on the Illinois River. Water samples collected at the reported locations detected microcystins above the 4 parts per billion (ppb) health advisory established by U.S. EPA.
The Illinois EPA and Department of Public Health have collected follow-up samples in the Illinois River which showed no evidence of the algal toxin, microcystin, including samples collected near Hennepin and Marseilles. It is likely that heavy rains that recently occurred in northern Illinois contributed to the improved conditions in the river.
Illinois residents should continue to use caution while recreating in, on, or near Illinois rivers, lakes or streams and be 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.
Do not let pets drink from water with any of the above characteristics.
Algal toxins (e.g., microcystin and cylindrospermopsin) sometimes produced by blue-green algae can cause sickness or other adverse health effects in people and pets, depending on the amount and type of exposure. The very young, elderly, and people with compromised immune systems are most at risk. Adverse health effects attributable to algal toxins can occur from direct skin contact, swallowing contaminated water, or inhaling water droplets in the air. Symptoms of exposure include rashes, hives, diarrhea, vomiting, coughing or wheezing. More severe symptoms may result from longer or greater amounts of exposure.
If you or your pet have come into contact with water you suspect may have a bloom of blue- green algae, rinse off with clean, fresh water as soon as possible. With all activities that may involve contact with lake or stream water, wash your hands before eating.
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.
