DOH issues toxic algae health alert for St. Lucie Canal in Martin County

Informational sign about blue-green algae blooms developed by the Florida Department of Environmental Protection

The public should avoid contact with toxic spanlgspane in the cspannspanl that connects Lake Okeechobee and the St. Lucie River, according to a state health alert issued Friday.

The cyanobacteria, more commonly called “blue-green algae,” contained the toxin microcystin measuring 0.62 parts per billion in water samples taken Feb. 22 in the C-44 Canal, also called the St. Lucie Canal, in Martin County.

At 8 parts per billion, the toxin makes water too hazardous to touch, ingest or inhale for people, pets and wildlife, according to the Environmental Protection Agency.

The toxic algae can flow farther east toward Stuart and the St. Lucie River because the Army Corps of Engineers is discharging excess Lake O water through the canal. The agency has been doing so since Jan. 22 to slowly lower the lake level in preparation of the June 1 start of hurricane season.

The Florida Department of Health in Martin County added signs warning of toxic blue-green algae in Spanish after Indian Riverkeeper Mike Conner made the suggestion.

The agency was not aware of the toxic algae and did not immediately answer TCPalm’s question about whether it will continue or suspend discharges.

The Florida Department of Health office in Martin County advises people to take these precautions:

  • Do not drink, swim, wade, use personal watercraft, water ski or boat in waters where there is a visible blue-green algae bloom.
  • Wash your skin and clothing with soap and water if you have contact with algae or water that’s discolored or smelly.
  • Keep pets away from the area. Water containing algae blooms are not safe for animals. Pets and livestock should have a different source of water when algae blooms are present.
  • Do not cook or clean dishes with water contaminated by algae blooms. Boiling the water will not eliminate the toxins.
  • 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 well.
  • Do not eat shellfish in waters with algae blooms.
