For the second time in two weeks, a no-swim advisory was issued for Siesta Beach.
The warning from the Sarasota County Health Department came Thursday, Aug. 11, the result of higher-than-acceptable concentrations of enterococcus bacteria. It was lifted Saturday, Aug. 13.
North Lido Beach and Lido Casino were also on the list. Water activities at all three beaches were not recommended, but the beaches remained open.
Water testing was performed Monday, Aug. 8, prompting the advisory. The bacteria can come from a variety of natural and man-made sources, and Sarasota County inspectors suspect decaying algae around the shoreline is likely the source.
Previously, Siesta Key received the same no-swim advisory on July 28, with it being lifted the next day.
