A bloom of the red tide organism, Karenia brevis, persists in Southwest Florida. Over the past week, K. brevis was detected in 52 samples, with bloom concentrations (>100,000 cells/liter) observed in six samples from Pinellas County, three samples from Hillsborough County, and four samples from Manatee County. Additional details are provided below.

In Southwest Florida over the past week, K. brevis was observed at background to high concentrations in Pinellas County (in 15 samples), very low to medium concentrations in Hillsborough County (in six samples), background to medium concentrations in Manatee County (in 12 samples), background concentrations in Sarasota County (in five samples), low concentrations in Charlotte County (in one sample), background to very low concentrations in Lee County (in 11 samples), and background to very low concentrations in Collier County (in two samples). Samples collected offshore of Monroe County did not contain K. brevis.

In Southwest Florida over the past week, fish kills suspected to be related to red tide were reported in Pinellas, Hillsborough, and Manatee counties. For more details, please visit:

Respiratory irritation suspected to be related to red tide was reported over the past week in Southwest Florida in Pinellas County. For current information, please visit:

Red Tide Respiratory Forecast

This online tool is a beach-level risk forecast activated during red tide conditions that tells beachgoers what red tide impacts are expected to be at individual beaches at different times of the day. It’s especially important for those who have asthma, COPD, or other chronic lung conditions and lets them know where red tide might be causing respiratory impacts so they can avoid those areas.

Caloosahatchee Conditions Report (June 15, 2021)

Flows to the Caloosahatchee Estuary had a 7-day average of 892 cfs at S-79 and a 7-day average of 842 cfs at S-77. The 14-day moving average flow at S-79 is 1,045 cfs and is within the optimal flow envelope (750 – 2,100 cfs; RECOVER 2020). Water clarity around Sanibel and Lee County remains good at this time. The harmful alga, Karenia brevis, persists in background to medium concentrations in Lee County. Algal blooms and strandings have been observed in Matlacha (Dapis pleousa), at Bowman’s Beach (Trichodesmium), and at Bunche Beach (Hypnea musciformis).

Red Tide

In Florida, red tide is caused by a microscopic single-celled algae called Karenia brevis or K. brevis. It is present in background conditions throughout the year in the Gulf of Mexico. When natural conditions are right, the organism can form blooms producing a toxin. When red tide is present it can cause coughing, sneezing and teary eyes. People with asthma or chronic respiratory problems should avoid red tide areas. Swimming in water with red tide can also cause skin irritation or eye burning.

Please refer to this fact sheet for more information on red tide.

Blue-Green Algae

Cyanobacteria/ blue-green algae are a group of organisms that can live in freshwater, salt water or mixed “brackish” water. When conditions are right, such as warm water and increased nutrients, these organisms can increase in numbers and accumulate in some areas of a water body.

Blue-green algae can cause gastrointestinal effects if swallowed. Children and pets are especially vulnerable. If you spot blue-green algae, please contact Kalina Warren, environmental administrator with DEP’s Water Quality Assessment Program for the South Region at 407-897-4177.

Vibrio Vulnificus

Vibrio vulnificus is a bacterium that normally lives in warm seawater. Itis part of a group of vibrios that are called “halophilic” because they require salt. Occurring naturally in the warm coastal waters, particularly during the summer months, Vibrio vulnificus has the potential to cause serious illness. People can get infected with Vibrio vulnificus when they eat raw shellfish, particularly oysters. Persons who have wounds, cuts or scratches and wade in estuarine areas or seawater where the bacteria might be present can become ill as well.

Symptoms of Vibrio vulnificus in wound infections typically include swelling, pain and redness at the wound site. Other symptoms of Vibrio vulnificus infection include; nausea, vomiting, abdominal pain, diarrhea, fever, chills and the formation of blistering skin lesions. Individuals experiencing these symptoms should contact a physician immediately for diagnosis and treatment.

Please refer to this fact sheet for more information on Vibrio vulnificus.
