Algal Bloom Response Summary:

“In response to reported algal blooms, the Florida Department of Environmental Protection (DEP),  the South Florida Water Management District (SFWMD), and Florida Wildlife Commission (FWC) coordinated efforts to survey and collect samples during the week of June 27. Sixteen samples were collected during the week from locations on the St. Lucie River and Inlet, Summa Beach Park, Bathtub Reef Beach, Jensen Beach, Hutchinson Beach, Ft. Pierce and Coral Cove. Reconnaissance was also conducted at Walton Rocks Beach and Jensen Beach but no samples were collected because no algae was present.

The sampling results from the week of June 27 indicate an elevated toxin level at the St. Lucie River at Central Marine Marina and at Bathtub Reef Beach, 15 feet from shore. Another sample taken at Bathtub Reef Beach closer to the shore was non-detect for toxins. St. Lucie Inlet near Sandsprit Park also had a toxin level slightly above the World Health Organization’s low-risk level for adverse health outcomes of 10 micrograms/liter. The Florida Department of Health at Martin County has issued an advisory encouraging Floridians and visitors to exercise caution when recreating to minimize their risk. If the water is discolored or a visible bloom is present, people are encouraged to stay out of the water, to keep pets and livestock out and to not use bloom water to irrigate lawns.

Since May 13, 2016, when the SFWMD first observed an algal bloom on Lake Okeechobee during their routine sampling, DEP and the SFWMD have regularly responded to and sampled observed and reported algal blooms on Lake Okeechobee, in the St. Lucie River and Estuary and the Caloosahatchee River and Estuary.

To date, a majority of the results continue to indicate low to extremely low levels of toxins. All results are reported to the Florida Department of Health, the Florida Fish and Wildlife Conservation Commission and the Florida Department of Agriculture and Consumer Services.

To see all results to date, please visit the Florida Algal Bloom Monitoring and Response webpage. We encourage you to bookmark the page and visit routinely as it will be updated in real time as new information becomes available. ”

Health Effects

DOH takes the lead in determining if a HAB presents a risk to human health. DOH issues health advisories as they determine to be appropriate when toxicity levels are higher and may also post warning signs when Florida Algal blooms affect public beaches or other areas where there is the risk of human exposure. These actions are typically directed out of local county health departments, most often in consultation with staff from DOH’s Aquatic Toxins Program. The World Health Organization considers levels under 10 micrograms/liter to represent a low-level risk for adverse health outcomes from short-term recreational exposures; however, certain sensitive populations (e.g., children, the elderly and immunocompromised populations) may still be at risk even at low concentrations and should avoid any exposure.

DOH also follows up on reports of pets that may have been exposed to a bloom, since these events may predict potential human health threats.”
