Legionella testing laboratory legionnaire's testing in drinking water

Legionella Testing

Legionella testing is more important than ever. Underutilized facilities have an elevated risk of a Legionella outbreak.

Legionella bacteria multiply within the single-cell organisms in water. When Legionella is aerosolized and inhaled, it can lead to infection. Legionellosis can result in Pontiac Fever and potentially-fatal Legionnaire’s disease. Individuals with a compromised immune systems are particularly susceptible to the disease. Information about Legionella in water, Legionnaire’s, and legionellosis is provided by the World Health Organization (WHO). Click here to view the WHO Fact Sheet.

Reopening facilities are at particularly high risk of Legionella contamination.
