Warning over deadly 'red tide' set to hit Florida in wake of hurricanes

Residents of Florida's Gulf Coast are facing yet different menace pursuing back-to-back hurricanes: deadly 'red tides.' 

Water samples and outer images person shown mean to precocious levels of Karenia brevis -  the benignant of algae that causes reddish tides - offshore of Tampa Bay.

Red tides hap when Karenia brevis grows retired of control, turning waters reddish-brown and producing a potent neurotoxin that tin beryllium suspended successful the aerial adjacent beaches. 

This toxin can termination food and sicken humans and pets with respiratory symptoms including shortness of breath, coughing and sneezing. 

In utmost cases, breathing reddish tide toxins can cause superior respiratory conditions specified arsenic pneumonia, bronchitis and worsening of asthma. 

Red tides tin crook deadly erstwhile respiratory symptoms go severe, oregon erstwhile a idiosyncratic consumes shellfish that has been contaminated by these toxins. 

This causes paralytic shellfish poisoning (PSP), which is fatal successful astir 8.5 percent of cases. 

'Karenia brevis (red tide) is contiguous on the seashore astatine concentrations that whitethorn cause respiratory irritation with onshore winds successful Pinellas and Sarasota counties,' the The National Centers for Coastal Ocean Science (NCCOS) presently states.

'A mean to precocious hazard of respiratory irritation is astir apt erstwhile winds are blowing onshore oregon alongshore, and little apt erstwhile winds are blowing offshore.'

Red tide toxins cause symptoms akin to an 'instant cold,' Richard Stumpf, an oceanographer with the National Oceanic and Atmospheric Administration (NOAA), told the Associated Press.    

Symptoms typically resoluteness wrong minutes of leaving the contaminated area, helium added. 

But for those with asthma oregon different underlying respiratory issues, symptoms whitethorn go superior oregon adjacent necessitate aesculapian attention.

And immoderate pets that person travel into interaction with reddish tide toxins person go earnestly sick oregon died. 

Red tides tin besides origin monolithic die-offs of food and different marine animals, covering beaches with rotting carcasses. 

In March 2023 for example, reddish tide caused countless dormant food to lavation up connected beaches on the Gulf Coast, particularly in Sarasota and Pinellas counties.

In Florida, reddish tide is astir communal successful precocious summertime and aboriginal fall, but researchers said that this year's menace was stirred up by Hurricanes Helene and Milton. 

Hurricanes bash not origin reddish tides, but they tin marque existing harmful algae blooms worse. 

The Florida Fish and Wildlife Commission reported medium and precocious levels of Karenia brevis concentrations successful immoderate coastal locations adjacent Pinellas County betwixt September 26 and October 3 - close erstwhile Hurricane Helene made landfall.

Hurricane Milton deed Florida soon aft connected October 9. 

Tropical storms churn up nutrient-rich h2o that feeds algae. 

They besides nutrient a batch of rain, which tin summation the magnitude of runoff from onshore and frankincense the magnitude of nutrients entering the water,

If a harmful bloom is already contiguous erstwhile a hurricane hits, the tempest tin substance its maturation and assistance a reddish tide form. 

A hurricane tin besides determination harmful algae blooms person to shore, sometimes pushing them hundreds of miles up the coast, Stumpf said. 

This increases their menace to quality health, making beachgoers and coastal assemblage members much apt to travel into interaction with reddish tide toxins

This reddish tide menace comes arsenic Floridians are inactive recovering from the interaction of back-to-back hurricanes.

Category 4 Hurricane Helene shattered records on Florida's westbound coast, delivering implicit 15 feet of flooding to the Big Bend portion and up to 10 feet of flooding successful different areas.
