Press Release: Wednesday, September 9th, 2026
Issued by: The Florida Department of Health in Monroe County
To: Residents and Visitors of the Florida Keys
Beach water quality testing performed by the Florida Department of Health in Monroe County has indicated elevated levels of enteric bacteria (enterococci) in the near shore waters at the following beaches: Jonh Pennekamp State Park Beach located in Key Largo, Founder’s Park Beach, Islamorada Library Beach & Ann’s Beach all three located in Islamorada; Higgs Beach, South Beach & Simonton Beach all three located in Key West.
Advisories have been issued for these locations.
The presence of enteric bacteria is an indication of fecal pollution, which may come from storm water runoff, pets, wildlife and human sewage. These bacteria may cause human disease, infections, or rashes. The Department of Health advises the public not to swim or practice other water-related activities in the near shore waters at these locations. This notice will remain in effect until bacteriological results show that the water is safe for such purposes.
The purpose of the Healthy Beaches Monitoring Program is to determine Florida’s beach water quality.

Good 0-35 Enterococcus sp. per 100 ml of marine water
Moderate 36-70 Enterococcus sp. per 100 ml of marine water
Poor 71 or Greater Enterococcus sp. per 100 ml of marine water
An Advisory is issued for a beach that samples in the “Poor” range of the EPA standards.
This should be considered a potential health risk to the bathing public.
