How Long Can Food Stay Safe in the Freezer Without Power?

When the power goes out unexpectedly, one of the biggest concerns is how long the food in your freezer will remain safe to eat. Understanding the factors that affect food safety during a power outage can help you make informed decisions and reduce food waste.

Factors Affecting Food Safety in a Power Outage

• Freezer Temperature Before Outage: A well-maintained freezer at 0°F (-18°C) keeps food frozen longer.
• Duration of Power Outage: The length of time without power directly impacts food safety.
• Type and Packaging of Food: Foods with higher water content freeze and thaw differently.
• Freezer Fullness: A full freezer retains cold better than a half-empty one.
