Swimming is not recommended at six local beaches and one is closed due to high levels of E. coli. The Windsor-Essex County Health Unit says six beaches — Belle River Beach, Colchester Beach, Holiday Beach, Mettawas Beach, Point Pelee and Seacliff Beach — are not currently recommended for swimming due to the presence of the illness-causing bacteria. The beaches are under a warning, meaning the waters are unsafe for swimming, but they remain open.
