State officials say seven public beaches in Michigan aren’t fit for swimming this weekend because of high bacteria levels.
As of Thursday, July 3, beaches were closed or under advisories due to high bacteria levels in areas across the state, according to the Michigan Department of Environment, Great Lakes and Energy, which provides that information via an online dashboard.
Beaches include:
County health departments routinely collect water samples for bacteria levels at beaches across the state to determine whether the water is safe for swimming, according to the EGLE.
To be considered safe for swimming, the E. coli counts must be below 300 per 100 milliliters.

The EGLE map lists information for beaches in Michigan, including water quality sampling results and beach advisories and closures.
The website also includes information on combined or sanitary sewer overflows, which lead to partially treated or untreated sewage being released into rivers and streams.
Why do officials check for E. coli?
Generally, coliforms are bacteria that are not harmful and are naturally present in the environment, according to the U.S. Environmental Protection Agency. They are used as an indicator that other, potentially harmful, fecal bacteria (indicated by the E. coli species) could be present.
If any routine or repeat sample is total coliform positive or present, the system (i.e., the lab) must further analyze that sample to determine whether E. coli are present. E. coli is a more specific indicator of fecal contamination and is a potentially more harmful pathogen than other bacteria typically found in the coliform group.
Consumption of or contact with water contaminated with feces of warm-blooded animals can cause a variety of illnesses, the U.S. Geological Survey said. Minor gastrointestinal discomfort is probably the most common symptom; however, pathogens that may cause only minor sickness in some people may cause serious conditions or death in others, especially in the very young, old, or those with weakened immunological systems.
What is swimmer’s itch? Does E. coli cause it?
Swimmer’s itch is a skin rash caused by an allergic reaction to microscopic parasites that infect some birds and mammals, according to the Centers for Disease Control and Prevention.
Swimmer’s itch is often incorrectly attributed to E. coli exposure, according to the Clean Lakes Alliance.
Symptoms can include:
What can I do about swimmer’s itch?
Swimmer’s itch typically clears up on its own within a week. If the itching is severe, your health care provider may recommend prescription-strength lotions or creams, the Mayo Clinic said.
Some home treatments may provide relief until it goes away:
