You might see a sign posted by the Iowa Department of Natural Resources at your favorite state park beach this summer.  Testing coordinator Mary Skopec says they will post of sign if their weekly tests show issues with blue-green algae and bacteria. “And if it is a bacterial impairment, normally what I have been telling people is very young children so babies, small toddlers, people with compromised immune systems  — people who are on chemotherapy drugs for example — should really avoid being in that water,” Skopec says.

Even if you are healthy, you should take some precautions if the beach is posted for a high level of bacteria. She says anyone with an open cut should avoid the water and everyone should avoid swallowing the water.  The recommendation involving algae is stronger. “When that advisory is due to the blue-green toxin, really people should stay out of that water because even contact with it for a healthy person can cause a pretty nasty skin rash,” Skopec says. “We can’t tell for sure always if everyone is going to get sick. The levels of toxin vary quite rapidly from day-to-day.”

She says the blue-green algae can also cause pets to get sick. Skopec says with the toxin advisory for the algae they recommend that people stay out of the water until it is clear and the advisory goes away. You can go online to see the results of the weekly testing. Go to www.iowadnr.gov/beaches to find the advisories. You can also call the hotline at: 515-725-3434.

Skopec says the levels of bacteria can change quickly if there is rain.  The blue-green algae tend to flourish when it is sunny and hot.
