UPDATE: The swim advisory issued for Vilano Beach was lifted on Sunday.
It's a bad idea to swim in the water at Vilano Beach, health department officials warned Friday.
There's a lot of fecal pollution in the water, which could come from storm water runoff, pets and wildlife and even human sewage, says an advisory from the St. Johns County Health Department.
Exposure to the excessive amount of bacteria which is commonly found in the digestive tract of humans and animals could lead to disease, infection or rashes, health officials say.
Poor water quality is graded at 70 colony forming units per 100 milliliters of marine water - there's currently 200 units at Vilano Beach. That's almost triple the amount considered poor by the Environmental Protection Agency.
The St. Johns County Health Department conducts bi-weekly tests of the water quality at six beaches in the county. They check from enterococci - the bacteria found in your digestive tract known to cause disease.
