The Beach Conditions Report provides several types of information about Southwest Florida beaches during Red Tide events: whether dead fish are present, whether there is respiratory irritation among beachgoers, what the water color is, the wind direction and what flags are currently flying at the beaches (for lifeguard-monitored beaches). Beach Conditions Report & Red Tide Informationīeach Conditions Report & Red Tide Information Beach Conditions Report.To help you know what you're harvesting, see how to identify bivalve shellfish. For this reason an area can be closed to varnish and butter clam harvest but open for other species. Varnish clams and butter clams store toxins longer than other species, and can remain toxic for more than a year after a bloom subsides. Their proximity to shallow beaches and fresh water sources (and thus potential pollution) are additional reasons to be especially aware of surrounding conditions when harvesting this species. Varnish clams accumulate toxin at higher levels than other species. Mussels accumulate toxins more quickly than other types of shellfish and are a good indicator species, alerting us that levels are on the rise. Questions? Call us at 36 or the local county health department during weekday business hours.List of Biotoxin Beach Closures by County.Recorded Hotline for Biotoxin Closures: 1-80.List of Public Beaches and Status by County.Other options to check if a beach is open or closed include: Don't assume a beach is safe if there are no signs – beach closure signs sometimes "disappear." Beaches are sometimes posted with warning signs. We regularly test shellfish for biotoxins and close areas when unsafe levels are detected. Check Before You DigĬheck the Shellfish Safety Map for beach closures and advisories on the day you plan to harvest shellfish. A popular misconception surrounds the term "red tide." This term is commonly associated with PSP toxin, but algal blooms that color the water red are generally harmless to humans. Harmful Algal Blooms Don't Always Color the WaterĪn area may be experiencing a massive bloom even though the water appears clear.

Life support systems such as respirators and oxygen are used in extreme cases to keep the victim alive and stable. ![]() Victims must wait for the toxins to naturally flush from their body. Cooking Does Not Destroy BiotoxinsĬooking will kill the algae that produces the toxin, but the toxin itself is not affected by cooking and remains in the shellfish tissue. Biotoxins don't harm shellfish, but they can accumulate in shellfish to levels that can cause illness or death in humans and other mammals that eat them. When shellfish eat toxin-producing algae, the toxin remains in their system large amounts of algae means more toxin can concentrate in their tissue. Algae is a food source for them, and HABs create a plentiful food supply. Molluscan shellfish (shellfish with hinged shells such as oysters, clams, and mussels) are filter feeders and ingest any particles, both good and bad, that's in the surrounding water. However, a combination of warm temperatures, sunlight, and nutrient-rich waters can cause rapid plankton reproduction, or "blooms." These blooms are commonly referred to as harmful algal blooms or "HABs" because of their potential to cause illness. Marine biotoxins are poisons that are produced by certain kinds of microscopic algae (a type of phytoplankton) that are naturally present in marine waters, normally in amounts too small to be harmful.
