Precautionary Boil Water Notices

Precautionary Boil Water Notices - Poring water for a tap into a glass.

In addition to boiling drinking water and water used for food preparation, food businesses need to take the following steps when a precautionary boil water notice has been issued:

Hand washing

It is advised that you provide hand sanitiser at each basin for use after staff have washed their hands. This is also advisable in customer toilets.

Ice making machines

You will need to discard existing ice. Use commercially manufactured ice from an unaffected water supply or use commercially bottled water in the ice machine.

Post-mix soft drink dispensing machines

When these are plumbed in to a water supply, they may not provide appropriate protection. We suggest switching to commercial bottled water.

Coffee machines

Check your water settings, as many coffee machines only heat the water to 85°C which is not hot enough to kill some contaminants. If you are unable to set your water to 100°C during a boil water notice, then you will need to use commercially bottled water.

Once the boil water notice has been lifted, food businesses will need to make sure they flush, clean, and sanitise, all equipment with water line connections such as post-mix beverage machines, coffee or tea urns, ice machines, glass washers, dishwashers, and other equipment with water connections.
