Collier County reported toxic blooms of the microscopic algae at medium levels at Barefoot Beach, at low levels at south Marco Beach and Seagate, and at very low levels at Vanderbilt Beach.
Red tide can kill marine life and cause coughing, sneezing and watery eyes in people, though the county hasn’t received reports of dead fish since Nov. 27 and just one report of respiratory irritation since Nov. 15.
The county staff is warning people with emphysema and asthma to use caution when going to the beach. More water samples are set to be taken Monday.
The Sarasota Herald-Tribune reports dead fish started washing ashore on Monday. Crews spent Thursday afternoon cleaning the beaches along Blind Pass, Manasota and Englewood Beach.
Sarasota parks and recreation director George Tatge calls the red tide outbreak “significant.”
He said most of the dead fish are large mullet. Tatge suspects a large school of mullet likely got caught up in a red tide bloom and washed ashore because of strong wind from the west.
