Nosocomial Illness and Mortality
A Legionella outbreak in a ward exposes immunocompromised patients to severe pneumonia and a real risk to life.
Sampling and Testing for Hospitals and Medical Facilities
A hospital concentrates the most vulnerable population - patients, surgical cases, and the immunocompromised - alongside large, complex water systems. Systematic monitoring of Legionella, drinking water, dialysis water, and food is an integral part of patient safety.

Hospitals - Sampling That Protects What Matters
The hot-water systems, cooling towers, taps, and end points in a hospital are an ideal environment for Legionella bacteria to multiply. When that water serves an immunocompromised population, even a low concentration can cause severe illness and fatalities. Alongside this, dialysis water, drinking water, and the food served in catering operations demand constant monitoring.
Kesar Digum builds and carries out an organized sampling program for your facility - hot- and cold-water systems, end points in sensitive wards, water for dialysis treatment, and food testing - and delivers the samples to accredited laboratories. The reports help you meet regulatory requirements and manage risk in real time.

Legionella Monitoring in Water Systems
Systematic sampling of hot-water systems, end points, and cooling towers - the primary risk in the hospital environment.
Full DetailsRapid PCR Legionella Test
Results within 24 hours when an outbreak is suspected or before a ward is reoccupied - critical in a medical environment.
Full DetailsDrinking-Water and End-Point Sampling
Microbial and chemical testing of drinking water and of end points in the wards, including sensitive units.
Full DetailsFood Testing in Catering Services
Sampling of food, surfaces, and drinking water in the institutional kitchen - to ensure food safety for inpatients.

Regulation
When Is Sampling Required?
The Ministry of Health's guidelines for preventing Legionella in medical facilities define when and how monitoring must be done. These are the main triggers:
Legionella Monitoring Program
A medical facility is required to maintain a documented monitoring program for its hot-water systems, per the Ministry of Health's guidelines for preventing Legionnaires' disease.
Suspected Illness Case
A diagnosed case of legionellosis or a suspected infection at the facility requires immediate sampling and investigation of the exposure source.
Water for Dialysis Treatment
Water used for hemodialysis treatment must meet strict quality requirements and undergo periodic testing.
Food Sanitation in Catering Services
The institutional kitchen is subject to food-sanitation requirements, which include sampling of food and surfaces for safety control.
The Risk
What Happens If You Don't Sample?
A failure to monitor water and food quality in a hospital directly endangers patients' lives and can shut down entire wards:
Ward Closure and Halted Operations
A serious finding sometimes requires closing a ward, halting patient admissions, and fully disinfecting the system - a heavy operational disruption.
Investigation and Institutional Liability
A documented infection incident triggers a Ministry of Health investigation, heavy institutional liability, and serious damage to public trust.
