If you're thinking of visiting the beach this weekend, make sure its at Cedar Beach, Cedar Island Beach, or Holiday Beach.
All of those have a clean bill of health after the Windsor Essex County Health Unit tested for bacteria this week.
One beach is closed. Lakeshore Lakeview West Park Beach, which had a posted warning last week, had an e.coli count of 1000.
Three other beaches have warnings posted. They are Colchester Beach, Point Pelee North West Beach, and Seacliff Beach.
Warnings are posted whenever the e.coli count is above 200.
