COLLIER COUNTY, Fla.- Sylvia Baptista had plans to spend the day before Thanksgiving at the Naples Pier.
"We're showing our in-laws you know the area," said Baptista.
But as soon as they got to the beach, they started feeling sick.
"We kept coughing. We thought maybe it was something blooming."
The cause of their coughing, experts said, the algae known as red tide.
"I think that you could feel a little tickle in your throat right now because the waves are so strong that the little particles of the algae are breaking off and you inhale them and you can feel them on your throat just slightly not very strong but slightly," said Mike Bauer, the City of Naples Natural Resources Manager.
The toxic bloom has been found in the water off Collier County beaches.
"We got some recent reports back and those indicated that there was some red tide about ten miles off shore due west," said Bauer.
Bauer said because of the holidays the timing is bad luck.
"Don't think it's related to any time of year, or anything specific, we do know that nutrients along the shore line increase it and cause it to get stronger and to last around longer."
And it's causing dead fish to pop-up along the sand at Delnor-Wiggins State Park, as well as discomfort for beach-goers.
"I guess we won't stay here too long," said Baptista.
The county will test the water again next Monday.
