Symptoms experienced during illness depend on the type of toxin present in the water and how a person is exposed (i.e., ingestion, skin contact, and inhalation). 2003;2:19-28. The Most Common Types of Freshwater Harmful Algal Blooms But sometimes, when conditions are right—warm water and increased nutrients—certain algae can quickly grow and overpopulate. Initial evaluation of the effects of aerosolized Florida red tide toxins (brevetoxins) in persons with asthma.external icon Environ Health Perspect. Eco-physiological diversity of the cyanobacteria genera that make up these blooms creates challenges for water managers tasked with controlling the intensity and frequency of blooms, particularly of harmful taxa (e.g., toxin producers, N2 fixers). Beaches and HABs: Successful expansion of the Florida red tide reporting system for protection of public health through community education and outreach.

Ansdell VE. Algae is the informal term used to describe photosynthetic organisms and includes a diverse list of organisms that range from single cells to multicellular that includes things like kelp or seaweed. Stewart I, PM Webb, PJ Schluter, LE Fleming, JW Burns, Jr., M Gantar, LC Backer, GR Shaw. Freshwater harmful algal blooms (HABs) have become a global concern because blooms contain cyanotoxins that can cause liver damage and other negative health impacts. MMWR Morb Mortal Wkly Rep 2020;69:1889–94. Blooms in fresh waterbodies are commonly due to cyanobacteria, which have the potential to produce toxins that affect humans, pets, and our ecosystems. Algal bloom concentrations may reach millions of cells per milliliter. Backer LC, Fleming LE, Rowan A, Cheng, Y-S, Benson J, Pierce RH, Zaias J, Bean J, Bossart GD, Johnson D, Quimbo R, Baden DG.
