Residents and visitors of Lake Weir are urged to exercise caution of getting in contact with the water of Lake Weir as blue-green algae blooms have been reported at certain locations.

The Florida Department of Health in Marion County issued a notice of blue-green algae at the Lake Weir Hope Boat Ramp and the Lake Weir Hampton Beach on Feb. 19.

While the bloom is not yet toxic, the algae “have the potential to produce toxins,” according to DOH Marion. The agency is conducting water sample testing.

“Blue-green algae can produce toxins, which can be harmful to human and pets as well as ecosystems, including fish and other aquatic animals. Sensitive individuals (e.g., children, the elderly and those who are immunocompromised) may still be at risk even at low concentrations and should avoid any exposure,” according to DOH Marion.

What to avoid:

• Avoid drinking, swimming or coming into contact with water where a bloom is visible. If contact is made, wash skin and clothes with soap and water.
• Do not allow any pets or livestock to contact the water.
• Do not cook or clean with contaminated water.
• Only eat meat from healthy fish caught in lakes with algae blooms.
• Avoid eating any shellfish from water contaminated with algae blooms.

To report an algae bloom, call 1-855-305-3903.

If you become ill from exposure to an algae bloom, report your symptoms to the Florida Poison Information Center at 800-222-1222.

If your pet has become ill after drinking or swimming in contaminated water, contact your veterinarian.
