ANNA MARIA ISLAND – Red tide has been detected in medium concentrations in Anna Maria Island waters, an increase from last week’s low concentrations, according to today’s Florida Fish and Wildlife Conservation Commission weekly report.
The toxic algae began appearing in mid-April after 215 million gallons of contaminated water was dumped into Tampa Bay from Piney Point, a former phosphate plant. The water contained the nutrients nitrogen and phosphorus, which act as a fertilizer for red tide. The discharge was approved by the Florida Department of Environmental Protection to prevent contaminated water in a holding pond on top of a compromised gypsum stack from flooding the area. Piney Point is the subject of two pending lawsuits and is in receivership.
Red tide dissipated in Manatee County from Aug. 30 until Sept. 14, when low concentrations were detected. On Sept. 21, medium concentrations were detected in water samples taken at the Rod n’ Reel Pier in Anna Maria and at the 10th Street Pier in Bradenton Beach. Low concentrations were detected at Key Royale (School Key) and the Longboat Pass boat ramp, according to the report.
Fish kills and respiratory irritation related to red tide were reported in Manatee County over the past week.
Red tide produces a neurotoxin called brevetoxin that can cause respiratory irritation, coughing, and more serious illness for people with severe or chronic respiratory conditions such as asthma, emphysema or COPD, according to the Florida Department of Health.
Health officials recommend that people experiencing symptoms stay away from the water and go inside to an air-conditioned space with closed windows and a clean A/C filter. Wearing masks, especially during onshore winds, is also advised.
Health officials warn against swimming near dead fish, and advise keeping pets away from dead fish and seafoam, which can contain high concentrations of red tide. Pets are not allowed on Anna Maria Island’s beaches but are allowed on the Palma Sola Causeway on Manatee Avenue.
Officials also warn that consuming shellfish exposed to red tide can cause neurotoxic shellfish poisoning.
