Power outages can be stressful, especially when you’re worried about the food in your refrigerator and freezer. Understanding how to safely handle food during these situations is crucial to prevent foodborne illnesses and minimize waste. This guide focuses specifically on how long food stays good in the freezer without power, helping you make informed decisions about what to save and what to discard.
Freezer Food Safety During a Power Outage
The length of time frozen food remains safe to eat during a power outage depends on several factors, primarily the fullness of your freezer and how long the power is out.
- Full Freezer: A full freezer will maintain a safe temperature for approximately 48 hours if the door remains closed.
- Half-Full Freezer: A half-full freezer will keep food safe for around 24 hours with the door closed.

It’s essential to keep the freezer door closed as much as possible during a power outage. Each time you open the door, cold air escapes, and the freezer’s internal temperature rises, shortening the safe storage time.
Determining Food Safety After a Power Outage
After a power outage, assessing the condition of your frozen food is critical. Here’s what to look for:
- Ice Crystals: The presence of ice crystals indicates that the food is still cold and hasn’t reached unsafe temperatures. Food that still contains ice crystals can generally be refrozen.
- Temperature: If you have a food thermometer, check the internal temperature of the food. If it’s 40°F (4°C) or below, it is generally safe to refreeze.
- Appearance and Odor: Discard any food that has an unusual color, odor, or texture.
Important: Never taste food to determine its safety. When in doubt, throw it out!
Refreezing Food: Quality Considerations
While some foods can be safely refrozen, keep in mind that the quality may be affected. Refreezing can alter the texture and flavor of certain foods.
Type of Food | Contains Ice Crystals and Feels Cold as if Refrigerated | Exposed to Temperatures of 40°F (4°C) or Above for More Than 2 Hours |
---|---|---|
Meat, Poultry, Seafood (all types of cuts) | Refreeze | Discard |
Stews, Soups | Refreeze | Discard |
Milk | Refreeze (some loss of texture) | Discard |
Eggs (out of shell) and Egg Products | Refreeze | Discard |
Ice Cream, Frozen Yogurt | Discard | Discard |
Cheese (soft and semi-soft) | Refreeze (some loss of texture) | Discard |
Hard Cheeses | Refreeze | Refreeze |
Shredded Cheeses | Refreeze | Discard |
Cheesecake | Refreeze | Discard |
Juices | Refreeze | Refreeze (discard if mold, yeasty smell, or sliminess develops) |
Home or Commercially Packaged Fruits | Refreeze (will change texture and flavor) | Refreeze (discard if mold, yeasty smell, or sliminess develops) |
Juices (Vegetables) | Refreeze | Discard after held above 40°F (4°C) for 6 hours |
Home or Commercially Packaged or Blanched Vegetables | Refreeze (may suffer texture and flavor loss) | Discard after held above 40°F (4°C) for 6 hours |
Breads, Rolls, Muffins, Cakes (without custard fillings) | Refreeze | Refreeze |
Cakes, Pies, Pastries with Custard or Cheese Filling | Refreeze | Discard |
Pie Crusts, Commercial and Homemade Bread Dough | Refreeze (some quality loss may occur) | Refreeze (quality loss is considerable) |
Casseroles: Pasta, Rice-Based | Refreeze | Discard |
Flour, Cornmeal, Nuts | Refreeze | Refreeze |
Breakfast Items: Waffles, Pancakes, Bagels | Refreeze | Refreeze |
Frozen Meal, Entree, Specialty Item | Refreeze | Discard |

Foods That Should Always Be Discarded After a Power Outage
Certain foods are more prone to bacterial growth and should be discarded if they’ve been exposed to temperatures above 40°F (4°C) for more than two hours. These include:
- Ice cream and frozen yogurt: These items melt quickly and can become breeding grounds for bacteria.
- Soft cheeses: Similar to ice cream, soft cheeses are highly perishable.
- Prepared foods and leftovers: These may contain bacteria that can multiply rapidly at higher temperatures.
Preparing for a Power Outage
Taking proactive steps can help minimize food loss during a power outage:
- Keep Freezers Full: As mentioned earlier, a full freezer stays colder longer.
- Freeze Water Bottles: Fill water bottles and freeze them to help maintain a lower temperature.
- Group Food Together: Organize your freezer so that items are close together. This helps them stay colder longer.
- Have a Thermometer: Keep a food thermometer handy to check the temperature of food after a power outage.
- Know Where to Get Information: Stay informed about the outage and estimated restoration time.
Conclusion
Knowing how long food stays good in the freezer without power is crucial for ensuring food safety and preventing unnecessary waste. Remember to keep the freezer door closed, assess food carefully after the power is restored, and when in doubt, throw it out. By taking these precautions, you can protect yourself and your family from foodborne illnesses during and after a power outage.
