How is Legionella spread in hot tubs?

Legionella is naturally found in water, especially warm water. Hot tubs (or spas) that are not cleaned and disinfected enough can become contaminated with Legionella. A person can get infected with Legionella when they breathe in steam or mist from a contaminated hot tub.

How do I protect myself, my family, and others?

Because high water temperatures make it hard to maintain the disinfectant levels needed to kill germs like Legionella, making sure that the hot tub has the right disinfectant and pH levels is essential. Our comprehensive Legionnaires’ Disease Bacteria Test For Hot Tubs In Hotels And Cruise Ships can you help determine where you stand.

 If You Are A Hot Tub Operator, Ask Yourself The Questions Below 

  • What was the most recent health inspection score for the hot tub?
  • Are disinfectant and pH levels checked at least twice per day?
  • Are disinfectant and pH levels checked more often when the hot tub is being used by a lot of people?
  • Are the following maintenance activities performed regularly:
    • Removal of the slime or biofilm layer by scrubbing and cleaning?
    • Replacement of the hot tub water filter according to manufacturer’s recommendations?
    • Replacement of hot tub water?

Hot Tub/Whirlpool Spa Comprehensive LegionellaTest

This comprehensive test provides everything that you need to know, to determine if your spa is safe from Legionella and other Pathogenic bacteria by including results with interpretation and recommendations. All six of these analyses can be run from one 250 ml water sample submitted to EST’s Laboratory.

  • Total bacterial count – a measure of the chlorine or bromine disinfection adequacy in the spa. – should be less than 200 cfu/ml (colony forming units per milliliter)
  • Escherichia coli– a public health indicator organism that is a measure of the contamination of the spa water with human feces. – should be None Detected or < 0.01 cfu/ml
  • Legionella pneumophila serogroup 1– should be None Detected or < 0.1 cfu/ml
  • Legionella pneumophila serogroups 2-14 – should be < 1 cfu/ml
  • Legionella(other species) – should be < 1 cfu/ml
  • Pseudomonas aeruginosa– a serious human pathogen for both normal and immunocompromised individuals – should be None Detected or < 0.1 cfu/ml
