Legionella Testing

CMS Mandates Reduction in Legionella Risk

In June of 2017, the Centers for Medicare and Medicaid Services (CMS) announced a mandate requiring all certified Medicare and Medicaid facilities to reduce the risk of growth and spread of Legionella bacteria and other opportunistic waterborne pathogens.  Facilities must develop water management plans to consider the ASHRAE 188P (formally American Society of Heating, Refrigerating & Air Conditioning Engineers) industry standard and include controls measures such as environmental testing for pathogens.  These standards are designed to not only reduce the risk of Legionella, but HPD and Pseudomonas, as well.  Any facility that does not comply with the mandate will risk a citation for non-compliance and would be in violation of the CMS Conditions of Participation.

As one of the leading microbiological laboratories, in the southeast, McCoy & McCoy Laboratories, Inc utilizes the latest advancements in automated and rapid microbiological technology. Our laboratory provides our clients with exceptional turnaround times and accurate results, all while offering individual attention throughout the testing and reporting process. 

Legionella pneumophila is the most common Legionella species in building water.  It's name was the foundation of the Legionnaires' disease.  This disease is a severe, often lethal, form of pneumonia.  Each year it is estimated that 10,000 to 18,000 people are infected in the United States and is caused by the bacterium Legionella pneumophila.

Legionella is naturally found in freshwater environments, like lakes & streams.  It becomes a health concern when it grows and spreads in our water systems.  Some areas of potential contamination are:

  • Showers and faucets                                                                  
  • Cooling towers (large air conditioning units)
  • Spas and pools
  • Hot water tanks & heaters
  • Large plumbing systems

McCoy & McCoy Laboratories, Inc (MMLI) is a nationally recognized water testing laboratory and has provided compliance testing for the water and wastewater industries since 1952.  Our laboratory utilizes the IDEXX Legiolert testing protocol, which provides timely and accurate culture test data.  While traditional culture methods take up to 14 days, our test results only take 7 for confirmed, quantified results.
