After testing water samples from the Illinois River, experts have confirmed the presence of microcystin, an algal toxin.

These samples were collected on Thursday, June 10, along the northern bank of the Illinois River at the Starved Rock Lock and Dam.

The samples had a microcystin level at 95.4 parts per billion (ppb). This is well above the health advisory limit set by the U.S. Environmental Protection Agency, which is 8 ppb.

The water was tested again on Wednesday, June 16. The results are pending.

According to state officials, algal toxins, which are sometimes caused by blue-green algae, may cause illness or other negative health effects in people and pets.

The side effects depend on the amount and type of exposure, but may include rashes, hives, diarrhea, vomiting, coughing, or wheezing.

Exposure can occur from direct skin contact, swallowing contaminated water, or inhaling water droplets in the air.

If you or your pet comes into contact with a bloom or blue-green algae, rinse off with clean, fresh water as soon as possible.

Do not let pets drink contaminated water or lick the scum from their fur.

In addition, people should wash their hands before eating after coming into contact with lake or stream water.

If you are concerned you have symptoms related to algal toxin exposure, contact your healthcare provider or the Illinois Poison Center at 1-800-222-1222.

If your pet is experiencing symptoms, call their veterinarian.
