When did it start?įlorida’s last devastating red tide event was recent – just two years ago in 2021. This photo shows dead fish washed up on Turtle Beach in Sarasota, Florida, amid a red tide event. The air on that beach, the resident said, felt as if there was pepper in it and was irritating their respiratory system. These effects have been seen in the most recent bloom, with one Florida resident sharing an image of a massive fish that they said looked like a goliath grouper washed up among other smaller fish on Turtle Beach in recent days. Burning eyes, noses and throats are common on beaches impacted by the tide, and experts say those who have chronic respiratory issues, such as asthma or emphysema, can have worse reactions. Some people can experience irritation within minutes of being exposed to the toxin as the wind and waves carry it into the air. Contaminated consumption can lead to nausea, vomiting, cardiovascular issues, neurological issues, and rashes, among other things.Įven if contaminated shellfish aren’t consumed, just being near a high concentration of the algal bloom can impact human health.
Brevetoxins tend to accumulate in shellfish, such as scallops and oysters, and if contaminated ones are consumed, it can cause neurotoxic shellfish poisoning, according to the CDC. Humans should also be concerned for their own health.
“Illness and death in Florida dogs have been linked to exposure to harmful algal blooms,” the agency warns. If those toxins are ingested by land animals, including pets, they can also cause “serious illness and death,” according to Florida’s Department of Health. brevis creates brevetoxins, which are a form of toxin that impacts fish and other marine vertebrates’ nervous systems and kills them, according to Florida Fish and Wildlife. Red tide’s toxic effectsįish kills are one of the most obvious – and putrid – impacts of red tide blooms.
At high concentrations of > 1,000,000 cells/L, there will also be visible water discoloration.īackground concentrations, meaning no effects are anticipated, were also detected in one sample from Destin Beach Okaloosa County, just west of Panama City, the department said on Friday. At that level, considered to be “medium,” it’s likely that people will experience respiratory irritation, shellfish harvesting will be paused and fish kills will be detected. In Southwest Florida, it was detected in 114 samples, including 56 that had medium to high concentrations of >100,000 cells/liter.
TOXIC RED TIDE FLORIDA UPDATE
On Friday, the Florida Fish and Wildlife Conservation Commission issued a status update for red tide conditions, saying that the organism was found in 115 samples along the state’s west coast. Red tide is a toxic algal bloom that originates dozens of miles offshore when there are high amounts of the algae known as Karenia brevis. Red tide, a problem that has sporadically plagued Florida’s Gulf Coast water for years, is back. ▶ Watch Video: Red tide ravages sea life and hurts tourism industry along nearly 100 miles of Florida’s Gulf Coastįlorida beaches are filling up with dead fish and coastal air is burning people’s eyes, noses and throats – and it’s all because of a tiny organism.
