What this means
Florida tests over 400 public beaches throughout the summer (May–September) for E. coli and algal toxins. A beach goes under advisory when E. coli exceeds 300 colonies per 100mL of water — that's the level the EPA links to a ~3.6% risk of gastrointestinal illness from swimming. A closure means contamination is severe enough that the beach is closed to the public.
What you can do
- Before swimming, check the EGLE BeachGuard daily list for your beach.
- Avoid swallowing lake water — most bacterial risk is from accidental ingestion.
- Don't swim within 24-48 hours of heavy rain (storm runoff carries the most contamination).
- If you swim at an advisory beach and feel sick within 5 days, call your county health department.
