Preventing Mould in Ice Machines: A Hidden Risk for Brisbane and Gold Coast Businesses

Mould in Ice Machines: A Silent Contaminant in Humid Climates

If you operate a café, restaurant, bar, or venue on the Gold Coast or in Brisbane, chances are your ice machine is working overtime. But in Queensland’s humid subtropical climate, that hard-working appliance could be hiding a problem you can’t afford to ignore: mould growth.

Why Ice Machines Are Prone to Mould

Mould thrives in warm, moist environments—exactly the conditions found in many commercial kitchens. Add in airborne yeast from bread, alcohol vapours from bar service, and infrequent cleaning, and your ice machine becomes a breeding ground.

Even though ice is cold, the inside of an ice machine often contains:

• Warm, damp air when the door is opened frequently

• Condensation that accumulates on walls and components

• Residual organic material that feeds microbial growth

Risks of Mould in Ice Machines

Mould in ice machines is not just unsightly—it’s a hygiene and health hazard. Mould spores can contaminate ice, which is then served to customers in drinks or used in food preparation. In severe cases, this can lead to:

• Complaints of off-tasting ice

• Food safety breaches

• Illness in vulnerable customers

• Damage to your business’s reputation

Brisbane and Gold Coast: A Perfect Storm for Mould

Queensland’s high humidity, especially during summer, accelerates mould growth. Coastal businesses near Surfers Paradise, Southport, Brisbane CBD, and even hinterland areas like Tamborine or Samford often struggle to keep moisture levels low enough to prevent mould from taking hold.

How to Prevent Mould in Your Ice Machine

Fortunately, with regular maintenance and a proactive approach, mould can be kept at bay:

1. Schedule Routine Cleaning
   Ice machines should be thoroughly cleaned and sanitised at least every 6 months—more often in high-use environments. This includes cleaning:

   • The bin interior

   • Ice chute and dispenser

   • Condenser coil

   • Water lines and filters

2. Use the Right Cleaning Products
   Avoid using general-purpose cleaners. Use only manufacturer-approved ice machine cleaning solutions that effectively target biofilm and mould.

3. Ensure Proper Ventilation
   Make sure your machine is installed in a well-ventilated area, with adequate airflow to reduce humidity build-up.

4. Sign Up for Preventative Maintenance
   ACRO Refrigeration offers Preventative Maintenance Agreements (PMAs) that include scheduled deep cleaning and inspections. This takes the pressure off your staff and ensures compliance with food safety standards.
