A dangerous organism that generates a toxic red tide is no longer being detected in state waters, the Florida Fish and Wildlife Conservation Commission said in a statement.
The microscopic alga, Karenia brevis, has impacted waters in the Sunshine State since 2017, killing thousands of sea turtles, manatees, dolphins and fish, and causing health issues in beachgoers.
FWC said it collected water samples on Wednesday from southwest Florida, northern Florida and along the eastern coast of the state without finding a trace of the organism.
The agency's website says, "Red tides can last as little as a few weeks or longer than a year." This most recent infestation was first reported in November 2017.
Local conservation groups are working with the FWC to replenish fish stocks decimated by the red tide.
