CAPE CORAL, Fla. -- A warning for swimmers in Cape Coral.  The Lee County Health Department says people should not swim at the Cape Coral Yacht Club Beach until further notice.  High levels of bacteria were found after a weekly round of tests were done.

Yellow advisory signs have been posted up and down the beach at the Cape Coral Yacht Club Beach, warning swimmers to stay out of the water because they could get sick from the bacteria.

John Lumba enjoys spending an afternoon taking in the beautiful scenery the Cape Coral Yacht Club Beach has to offer but he tends to stay out of the water.

"I do fish in it, I do boat in it but I live blocks away so I come down here and I read and just watch the tranquility of the water, the birds and the people," said Lumba.

Lumba wasn't surprised Tuesday, to see yellow signs dotting the sand at his favorite relaxation spot.  The signs are advisories warning swimmers to stay out of the water.

"Its a health concern and people should adhere to it.  Its unfortunate but it does happen," said Lumba.

The Lee County Health Department posted the signs after a round of weekly tests came back showing high levels of bacteria.  If people come in contact with the water, it could cause diarrhea and abdominal pain.  Not all swimmers are listening to the advisories.

"You know its hot.  Air is out at the house today so we thought we'd chill in the water instead.  Just don't go under, don't let it get inside your ears," said David Marris, a swimmer.

Others are heeding the warnings and staying on the sand.

"We've been here since May and we've never seen these signs up and we've been in the water several times and just sad that we cant partake of the natural resources," said Michael Dagostino, a beach goer.

The increased levels of bacteria are a sign of pollution from storm water runoff, pets, wildlife or sewage.  All of that is something Lumba says he's seen before and says if he wanted to, he'd take a dip.

"Its fairly safe.  They don't suggest you ingest the water because of upset stomach or what not but I'd go in the water.  I'm not fearful of it.  Its something that we deal with," said Lumba.

Another around of test results are expected back Thursday by 3:30 p.m.  A new round of water samples on all Lee County beaches will be taken Monday, October 3, with results showing 24 hours later.
