Organism Karenia brevis Detected in Minimal Concentrations in Northwest and East Florida, While Southwest Coast Shows No Presence
A recent report from the Florida Fish and Wildlife Conservation Commission (FWC) indicates that red tide activity across the state remains at low, “background” concentrations, with no significant blooms, fish kills, or respiratory irritations reported over the past week.
The red tide organism, Karenia brevis, was detected at background levels in just two samples statewide. One sample was collected from Bay County in Northwest Florida, and another was found in Flagler County on Florida’s East Coast. This marks a continued period of minimal activity for the organism, which is a naturally occurring component of the Gulf of Mexico’s marine ecosystem.
Notably, in Southwest Florida, a region often heavily impacted by Karenia brevis blooms, the organism was not observed in any samples collected over the past week. This absence of detection is a positive sign for coastal communities and local tourism in the area.

Officials are also reporting no instances of fish kills suspected to be related to red tide, nor were there any reports of respiratory irritation—a common human health effect when the organism is present in higher concentrations.
Looking ahead, a collaborative forecast from the USF-FWC Collaboration for Prediction of Red Tides for the coastal areas from Pinellas to northern Monroe counties predicts a net western transport of surface waters, suggesting that any existing organisms will be moved away from the shoreline.
The FWC continues to monitor conditions closely using satellite imagery and water sampling. The next status report is scheduled to be released on Friday, September 19.
