Stay Informed

Florida Department of Health: The Florida Department of Health (DOH) provides education to the public to prevent and reduce illnesses caused by harmful algae blooms.

Algae bloom toxicity levels: The Florida Department of Environmental Protection (DEP), Florida Fish and Wildlife Conservation Commission (FWC) and Florida’s water management districts collect samples when algae blooms are observed. 

Suspected algae-related illness: Citizens are advised, if they have any suspected algae-related illness or health effects due to exposure to algae, to see their physician and report any suspected illness to the Florida Poison Control Center at (800) 222-1222.

Stay Away

From the Florida Department of Health:

In water bodies with blue-green algae, if people or animals splash or if boats create wakes, the cyanotoxins in the algae can release into the air.
The toxins mix with water droplets and spray—that’s how people and animals can inhale the toxin. These toxins can’t pass through your skin easily so swallowing large amounts of contaminated water is what causes illness. This algae is blue, bright green, brown or red, and can have a strong odor like rotting plants. Pets can become sick from blue-green algae so keep them out of those areas and away from contaminated marine animals and fish.

SYMPTOMS? Stay away from blue-green algae.  For some people, blue-green algae can cause rashes, stomach cramps, nausea, diarrhea and vomiting. People who are very sensitive to smells can have respiratory irritation. Sometimes, high exposures of toxin can affect the liver and nervous system.
If you come into contact with blue-green algae, get out of the area and wash off with soap and water. See your doctor if you think blue-green algae has made you sick.

CONTAMINATED WATER  Water from areas with blue-green algae can make animals and people sick—stay away from these areas.
