Two in Charlotte County. 10 in Lee County, and one in Collier County. Additional details are provided below.
- In Southwest Florida over the past week, K. brevis was observed at background concentrations in Pinellas County. Very low to medium concentrations in Manatee County. Very low to high concentrations in and offshore of Sarasota County. Medium and high concentrations in Charlotte County. Very low to high concentrations in Lee County, and medium concentrations in Collier County.
- In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample from Santa Rosa County.
