Bloom Monitoring and Notification 

WHAT IS THE DEPARTMENT DOING? The Department of Health (DOH) works closely with its partner agencies, the Department of Environmental Protection (DEP) and the Fish and Wildlife Conservation Commission (FWC). Together, the three agencies have established a collaborative protocol for the monitoring and public notification of algae blooms in state waters to protect Florida citizens and visitors from exposure. 

DEP and their partners conduct sampling and testing of freshwater for blue-green algae, while FWC samples and tests marine waters for red tide. DOH gathers the data from both agencies to develop Health Cautions and Health Alerts and works to distribute the information to affected county health departments (CHDs) in Florida. The CHDs relay the information locally through established notification channels. Publicly issued press releases can be found on our Where are HABs?  page, or on the county health department’s website. Please contact your local county health department for further information on messaging methods. 

The Department of Health uses a two-tiered notification process, consisting of Health Cautions and Health Alerts. For blue-green algae, a Health Caution notification is based on the presence of a bloom, and/or cyanobacterial dominance, and a Health Alert is issued on the basis of toxin detected.

With concurrence from DEP and input from Florida’s Blue Green Algae Task Force, these conservative thresholds were selected over numeric criteria because they offer the greatest protection as conditions change. It typically takes no less than 3 days to collect, ship, analyze, and report sampling results, and in that time, algae distribution can change significantly. Basing public health notifications on the presence of cyanobacteria, cyanobacterial dominance, or toxin detection gives the public timely information in case conditions worsen.

Red tide Health Cautions and Health Alerts are based on numeric thresholds set by FWC. Health Cautions are based on Karenia brevis cell concentrations in the range of 10,000 to 100,000 Karenia brevis cells per liter of water. Health Alerts are issued when concentrations reach greater than 100,000 cells per liter.
