Legionella Testing in Water

Legionella bacteria multiply in hot water systems, cooling towers and neglected pipework, and cause severe pneumonia. Periodic sampling by certified samplers, with testing at an ISO 17025 accredited laboratory, detects the bacteria before it becomes a disease outbreak - nationwide.

Legionella Testing

Detect Legionella before it detects you

Legionella is a bacterium that multiplies in warm, standing water - in water heaters, cooling towers, showers and neglected pipework - and spreads through aerosol droplets that are inhaled into the lungs. For healthcare institutions, hotels and public buildings, periodic Legionella sampling is part of a mandatory infection-control program. Kesar Digum collects the samples on site through certified samplers, sends them for testing at an accredited laboratory, and returns a clear report with recommended actions.

What the service includes

What we sample

Targeted sampling at the points where Legionella tends to multiply - based on a survey of the water system.

Hot water system sampling

Samples from end points, the water heater and the return loop - where lukewarm temperatures invite Legionella growth.

Cooling tower sampling

Monitoring of cooling towers and water-cooled HVAC systems, a common source of Legionella outbreaks over a wide radius.

Rapid Legionella PCR Test

Results within 24-48 hours using molecular PCR, for emergencies and suspected outbreaks.

Full Details

Disinfection after a positive result

Treatment and disinfection of the water system following a positive result, with repeat sampling for confirmation.

Full Details
Regulation

When is Legionella testing required?

The Ministry of Health requires Legionella monitoring in a range of facilities. These are the common cases where sampling is needed:

Healthcare and welfare institutions

Hospitals, nursing homes and assisted living are required to carry out periodic Legionella monitoring as part of their infection-control procedure.

Periodic

Hotels and public buildings

Hot water systems, showers and spa pools in public buildings require ongoing monitoring to prevent exposing guests.

Periodic

Cooling towers

Cooling towers and water-cooled HVAC systems are a primary source of outbreaks and require sampling at fixed intervals.

Ongoing monitoring

Suspected outbreak

A suspected illness case or a previous positive result require immediate sampling, usually by rapid PCR.

Per event
The risk

What happens when Legionella is neglected?

Legionella that is not monitored turns from a hidden hazard into a disease outbreak. Here is what is at stake:

Legionnaires' disease

Inhaling contaminated aerosol causes severe pneumonia, which can be life-threatening, especially among vulnerable populations.

At-risk populations

Inpatients, the elderly, smokers and the immunocompromised are especially exposed to severe illness from Legionella.

Regulatory and legal exposure

Failure to comply with Ministry of Health guidelines exposes the institution to audit findings, closure and lawsuits in the event of illness.

Schedule sampling

Need to schedule a Legionella test?

We will map the water system, take representative field samples and return a report with results and recommendations - including an option for rapid PCR testing in an emergency, nationwide.
