When there is a power outage

When a power cut is ongoing (that is, it cuts for more than 4 hours and there is no immediate likelihood of reconnection) food safety becomes an important issue.

Unless cold storage is available within 2 hours of a power cut, all potentially hazardous foods that are stored in refrigerators or chillers need to be:

• placed in alternative cold storage, for example eskies with ice or ice bricks, or family and friend’s fridges.
• eaten immediately.
• thrown away if another cold storage area is not immediately available.

Time and temperature are the most important measurements used to determine whether food needs to be regarded as potentially unsafe.

Sudden of unplanned power cuts

 Sudden or unplanned power cut will not allow much time for you to safely store your foods. Your food will remain safe in your refrigerator for 2 hours, but there are some steps you can take:

• If you have sufficient space in the freezer, after 2 hours you should remove foods from the fridge. Place them in the freezer or esky with ice bricks.
• Do not open the freezer door unless necessary, as this will reduce the time the contents will remain frozen.

If your freezer is efficient, and its door seals are in good condition, it can maintain foods in a frozen state for between 1 and 2 and a half days.

• Relatives, friends or neighbours may be able to provide alternative storage.

Food stored in refrigerators

Your food will remain safe in your refrigerator for 2 hours. If it has been more than 4 hours, throw the food out.

Don’t open the fridge door during the power cut, unless necessary.

The best option is to find immediate refrigerated storage or place items in the freezer.

If this is not possible:

• Remove ice bricks from the freezer and place in an esky.
• Remove all meats, poultry, dairy and potentially hazardous food (for example dips, pâté, ham and salami) from the refrigerator and place in esky.
• Place the ice or ice bricks throughout the stored food to prevent hot spots developing. Make sure the lid of the esky has a good seal.
• If the temperature of the food stored in an esky or refrigerator reaches more than 5 °C for less than 2 hours you have 2 options:
• Find alternative refrigeration at less than 5 °C or if available freeze
• use immediately.

Use immediately any food stored in a refrigerator or esky at more than 5 °C for more than 2 hours but less than 4 hours.

Food stored in a refrigerator or esky at more than 5 °C for 4 hours or more should be thrown out.

Food stored in freezers

• Freezers that are in good condition and operate at minus 15 °C or below can keep foods frozen for between 1 and 2 days. If the freezer door is kept shut, a full freezer can keep food frozen for up to 48 hours, while a half full freezer can kept food frozen for 24 hours.
• It is important that the doors of freezers are not opened unless necessary. Opening and closing the doors will reduce the time the contents will remain frozen.
• Remember that some food types, for example ice cream, will become soft and begin to separate long before other foods defrost. Although there is no safety issue, such foods become icy when refrozen and may not be usable after defrosting and refreezing.
• Foods that have partly defrosted or defrosted but remain very cold (5 °C or less) can be refrozen. Note that while there will not be a food safety issue in refreezing defrosted foods, the quality of the food may be slighted deteriorated.
• You have 2 options for food that has been stored in a freezer where the temperature has reached more than 5 °C for up to 2 hours:
• Find alternative refrigeration at less than 5 °C or refreeze.
• Consume immediately.

If your food has been in a freezer where the temperature has reached more than 5 °C for more than 2 hours, but less than 4 hours, it should be consumed immediately.

Food stored in a freezer for more than 4 hours at more than 5 °C should be thrown out.

Disposal of food

When you dispose of food, wrap it in newspaper and place in the rubbish bin. A small volume of food may be safely buried.

Where larger quantities must be disposed of, contact Environmental Health Services at your local government. Without correct disposal, fly breeding may result and increase the risk of the spread of infectious diseases.

If in doubt, dispose of the food safely.
