Ice Machines and Legionella

A Growing Problem

Ice Machines and Legionella

Each day people all over the world are exposed to ice. Whether it be from their refrigerator ice machine, their favorite restaurant, during their hospital stay, or on an airplane, people sip on their ice cold beverages or suck on ice chips unaware of the microorganisms that could be sitting dormant within the ice.

Legionella: To Sample, or Not To Sample?...That is the Question

What's required and what is my sampling plan?

Legionella: To Sample, or Not To Sample?...That is the Question

The simple answer is no (not directly), and here’s why:  There is no known safe level of Legionella in a building water system.  Therefore, even a non-detect sample result is not necessarily “safe.” The reason why is because the life cycle of this organism, coupled with the stresses put on it via temperature, disinfectants, etc. found within building water systems, may cause it to enter a viable but non-culturable (VBNC) state.
