The St. Clair County Health Department has flagged Holland Beach as unsafe for swimming due to high levels of E. coli bacteria. Routine weekly testing revealed that water samples exceeded the state’s safety limit of 300 E. coli per 100 milliliters. Health officials warn that exposure can lead to stomach issues, skin infections, or worse. The spike is likely due to recent rain and runoff, which can wash animal waste into the water. Updates on beach closures are posted on the county’s Beaches social media page.
