In 2018, cyanobacteria from nutrient-rich waters in Lake Okeechobee were released down the Caloosahatchee river at the same time that red tides were gathering along the western coast of Florida, potentially exposing coastal residents to a mixture of toxins. In 2018, releases of cyanobacterial-laden freshwater from Lake Okeechobee transported a large bloom of Microcystis cyanobacteria down the Caloosahatchee. Analysis of water samples showed high concentrations of microcystin-LR, sufficient to result in adverse human and animal health effects if ingested, based on the known toxicity of this cyanotoxin.
