Midweek Red Tide Update (May 22, 2013)
Karenia brevis, the Florida Red Tide organism, was detected at background to very low concentrations in several samples collected alongshore of Pinellas, Manatee, Sarasota and Lee counties so far this week. Other samples collected in southwest Florida did not contain K. brevis.
In other parts of Florida, K. brevis was not detected in samples collected in the Indian River Lagoon (Brevard County) or alongshore and offshore of Okaloosa, Walton and Broward counties.
Sampling will continue this week, and complete results will be available in the next scheduled status report on Friday, May 24.
