Health Topics and Links: Food Safety After a Power Outage
Please follow this advice to avoid becoming ill from food after a power outage.

For residential homes:
NH Department of Health and Human Services (DHHS) recommends taking the following steps during and after a loss of electrical power:
- Never taste food to determine its safety
- Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature
- The refrigerator will keep food safely cold for about 4 hours if it is unopened. A full freezer will hold the temperature approximately 48 hours (24 hours if it’s half full and the door remains closed)
- Food can be safely refrozen if it still contains ice crystals or is at 40ºF or below
- Get block ice or dry ice to keep your refrigerator and freezer as cold as possible if the power is going to be out for an extended period of time
- Discard refrigerated perishable food such as meat, poultry, fish, soft cheeses, milk, eggs, leftovers, and deli items after 4 hours without power
- When in doubt, throw it out.
For retail establishments:
Retail establishments are reminded that they should cease operation and contact the Food Protection Section when they have experienced any of the following:
- Disruption of water service or interruption of electrical service for longer than 2 hours,
- Have a contaminated water supply or failed sewer system
Consumers or establishments can reach the NH DPHS Food Protection Section at 603-271-4589 or after business hours at 603-271-5300; or by email at foodprotection@dhhs.state.nh.us.
