Legionella bacteria are intracellular pathogens. When absorbed by protozoa/amoebae, they are able to prevent the internal enzyme breakdown. Alveolar macrophages are the primary defense against bacterial infection of the lungs and work in exactly the same way. The legionella bacteria can therefore multiply in the bodies own defense before rupturing the host and spreading to other macrophages.
The primary route of infection is the inhalation of aerosols contaminated with legionella bacteria into the lungs.
C-CHEC can provide
- Full Legionella Risk Assessment strategy using C-CHEC's own practical scoring system
- Water management visits for water testing, shower head disinfection, etc.
- Annual audits looking at records for temperature, laboratory testing, dead-leg flushing (an area in a piping system where water can become stagnant), etc.
If you have water systems on your site, cold needs to be below 20
oC and hot above 50
oC. We will advise on how to measure and what the implication of deviations are.
