Our experience with the cruise industry

In 1995 EST was establishing itself as a premier Legionella laboratory bolstered by Dr. Richard Miller’s extensive background in Legionnaires’ Disease (LD) and Legionella detection.   When a call came in from the cruise industry experiencing cases of LD on a vessel, we swiftly leapt into action responding to the customer with a visit to the ship for an inspection of the water systems.  This allowed us to quickly assess the risk to those aboard and develop a sampling strategy to not only solve the current issue but prevent future cases of LD. 

From this initial sampling we were able to develop a comprehensive sampling strategy and project management system that would provide validation for fleets large and small.   By coordinating directly with port agents and ship personnel we can provide sampling kits directly to the port at the time that is most optimal for the ship to sample and return the samples to our laboratory.  Maximizing the viability of the samples while minimizing the workload for ships personnel.   With our new Viable Legionella vPCR test, we can provide Legionella answers while the vessel is in port between cruises.

As cruise lines move to more comprehensive water management plans and tighter schedules, we have moved to increase our services to provide them with even faster and more reliable results.  The introduction of our Viable Legionella vPCR sampling can provide answers in as little as four hours from the time that the samples are received in the laboratory.  Allowing ships to sail with confidence that their water systems are not at risk for a LD outbreak.  Click the button below to learn more about Viable Legionella vPCR.

COVID-19 and Legionella

The impact COVID-19 has had on everyone extends to building water systems, both cooling towers, and potable water systems. Inactivity and limited use can contribute to the formation of biofilm allowing for Legionella proliferation. EST can assist in developing a reopening plan for your facility, including highly effective re-commissioning disinfection procedures and follow-up validation testing.
