Ice Machine Bacteria Testing & Prevention

Why Test for Bacteria in Ice Machines?


  1. Help establish a proactive water safety program
  2. Keep guests safe from harmful bacteria responsible for pneumonia and gastrointestinal disease
  3. Reduce liability and risk to ownership
  4. Help catch potential bacteria control issues before human infection
  5. Comply with Environmental Protection Agency (EPA) and World Health Organization’s (WHO) standards for drinking water quality


Available Laboratory Tests to Help Insure Ice Machine Water Quality

Total Heterotrophic Bacteria Count – An analytical method used to measure the variety of bacteria that are common in water. The lower the concentration of bacteria in drinking water, the better maintained the water system is. Validation Criteria: <1000 CFU/mlLegionella Test – A test for the bacteria responsible for Legionnaires’ disease, a type of pneumonia. Validation Criteria: <10 CFU/ml viable to LegionellaTotal Coliforms – Used to indicate whether bacteria that may cause gastrointestinal disease is present. Every sample must be analyzed for total coliforms and E. coli. Validation Criteria: <1 CFU/ml
