Department of Health warns about algae in Winter Haven's Lake Conine. What to know

The Florida Department of Health in Polk County has issued a health alert for the presence of harmful blue-green algal toxins in Lake Conine in Winter Haven.

The warning comes in response to a water sample taken on April 2.

What is blue-green algae?

Blue-green algae are a type of bacteria that is common in Florida's freshwater environments, the agency said in a news release. A bloom occurs when rapid growth of algae leads to an accumulation of individual cells that discolor water and often produce floating mats that emit unpleasant odors.

Some environmental factors that contribute to blue-green algae blooms are sunny days, warm water temperatures, still water conditions and excess nutrients. Blooms can appear year-round but are more frequent in summer and fall. Many types of blue-green algae can produce toxins.

What are the warnings?

Residents and visitors are advised not to drink, swim, wade, use personal watercraft, water ski or boat in waters where there is a visible bloom.

Wash your skin and clothing with soap and water if you have contact with algae or discolored or smelly water, and keep pets away from the area, the department said.

Is it safe to eat fish?

Eating fillets from healthy fish caught in freshwater lakes experiencing blooms is safe. Rinse fish fillets with tap or bottled water, throw out the guts and cook fish to the appropriate temperature.

The Florida Department of Environmental Protection collects and analyzes algal bloom samples. To report a bloom to DEP, call the toll-free hotline at 855-305-3903 or report online.
