The Importance
Why Regular Testing Matters
Legionella and Pseudomonas bacteria can form in almost any building’s water system. Routine testing provides proof that temperature control, flushing, and disinfection are effective - giving you documented evidence for CQC inspections, insurers, and HSE audits.
Testing helps you:
Detect early signs of contamination before they become outbreaks
Demonstrate due diligence and compliance
Protect residents, staff, and visitors
Avoid costly remedial work later
Understanding the Risk
Legionella vs Pseudomonas - Why Test for Both
- Legionella causes Legionnaires’ disease via aerosol inhalation from showers, taps, cooling towers and cooling systems.
- Pseudomonas aeruginosa spreads through contact and colonises biofilms in cold outlets, posing a serious risk in health and safety.
- The two bacteria thrive in different conditions and require different remedial actions if detected.
- Testing for both provides full assurance that your controls are working.
