Legionella Testing Services

Orlando, Florida, February 7, 2025

Recently, multiple media outlets reported on the death of an elementary school teacher in Pinellas County due to Legionnaire’s disease. The local school district and department of health are investigating possible sources of the Legionella bacteria that caused the death. Students from the building where she taught have also been temporarily moved to other locations.

Legionnaires’ disease is a serious type of pneumonia. The bacteria can also cause a less severe illness known as Pontiac fever. While the bacteria can be found naturally in freshwater environments, it becomes a health concern if it grows and spreads in man-made building water systems. This is due to the fact that water containing Legionella can spread in droplets small enough for people to inhale.

“Building water systems and devices listed by the Centers for Disease Control and Prevention where Legionella could grow and spread include showerheads and sink faucets, cooling towers, hot tubs, decorative fountains and water features, hot water tanks and heaters, and large plumbing systems,” said Jason Dobranic, Ph.D., Vice President of Microbiology and Life Sciences at EMSL Analytical, Inc. “Tragically, as this case illustrates, Legionnaires' disease can be fatal.”

To support proactive water management programs or to identify the source of an outbreak if one has already occurred, EMSL Analytical offers rapid PCR and Whole Genome Sequencing methods, as well as traditional culturing methods, to identify Legionella from environmental samples. These same tests can be utilized to confirm remediation and disinfection efforts have been successful after the discovery of the bacteria. EMSL has a Legionella testing laboratory in Florida and a number of their laboratories have received the CDC’s Certificate of Proficiency from its Elite Program for Legionella testing. Some are also NYSDOH ELAP Legionella certified.

To spread awareness of potential Legionella exposure risks, EMSL has sponsored an educational video that can be seen at: https://youtu.be/ZP9AotQ2_gE
