The City of Plymouth has closed all of its public beaches due to high levels of bacteria.
The city announced the closures Tuesday, which will be effective through the rest of the summer. The closures are a frequent occurrence for beaches across the metro area and are caused by naturally-occurring bacteria.
In particular, city officials are concerned about E. coli in lakes. According to the Mayo Clinic, exposure to water contaminated with E. coli can lead to nausea, vomiting and abdominal cramping.
In Plymouth, outbreaks are typically associated with animal waste from geese and other waterfowl, introduced directly or through rainstorm runoff.
The city is advising against swimming, kayaking and other recreation activities at its lakes and beaches.
Similar moves are being taken in response to rising bacteria levels in response to warming temperatures across the Twin Cities.
Earlier this week, the City of Edina issued a warning for residents not to touch the water in Lake Cornelia, amid concerns over toxic algae.
And the City of Minnetonka has banned swimming in Shady Oak Lake due to rising levels of E. coli.
