Understanding Positive Legionella Results
A positive Legionella result indicates the presence of Legionella bacteria in your water system, commonly measured in colony-forming units per litre (CFU/L). The required actions depend on the concentration of bacteria found, the type of facility involved, and the risks posed to occupants.
Positive results need not cause panic, but they require prompt action to prevent potential health risks, especially Legionnaires’ disease. This serious respiratory infection can affect anyone but poses higher risks for older adults, smokers, and those with weakened immune systems.
Immediate Steps to Take After a Positive Legionella Result
Don’t Panic, but Act Promptly
Quick action is essential to contain any potential spread of Legionella bacteria. A calm, structured response will help address the issue effectively.
Review Test Results
Check the test results thoroughly to understand the severity. Levels below 1,000 CFU/L may require only retesting, while levels above this threshold typically require immediate intervention.
Notify Relevant Stakeholders
Inform all necessary stakeholders, including property management, building occupants, or internal health and safety teams. Open communication helps reduce concern and facilitates cooperation.
Implement Immediate Control Measures
Put control measures in place, such as limiting the use of water outlets or using temporary point-of-use filters for high-risk areas.
Contact a Legionella Specialist
Engage a Legionella control expert, like PTS, who can assess the situation, advise on corrective actions, and handle the remediation process professionally and safely.
