Power Outage Food Safety: What to Keep, Refreeze, or Throw Away

Start With Time, Temperature, and the Door

Standing in front of a warm refrigerator after an outage is not the time to negotiate with leftovers. Start with three facts: how long the power was out, whether the doors stayed closed, and whether the food stayed at 40°F or below.

According to the CDC, a refrigerator can keep food within the safe range for up to 4 hours if the door stays closed. If the outage lasted more than 4 hours and there was no cold source, treat perishable refrigerated foods as discard-first items. That includes meat, seafood, cut fruit and vegetables, eggs, milk, and leftovers.

A closed freezer buys more time. A full freezer can hold temperature for about 48 hours, while a half-full freezer is closer to 24 hours. If frozen food still has ice crystals or measures 40°F or below, it can usually be refrozen or cooked. The quality may suffer, but the safety decision is based on temperature and condition, not smell.

What to Do Before You Sort Anything

1. Write down when the power went out.
2. Keep the refrigerator and freezer doors closed.
3. If you have an appliance thermometer, check whether the refrigerator is 40°F or below.
4. If the outage is approaching 4 hours and you have ice, gel packs, and a cooler, move perishable refrigerated foods only if you can keep them at 40°F or below.
5. When power returns, sort food by category instead of deciding item by item from memory.

Do not taste food to check it. If a food smells strange, has an unusual color, or has a changed texture, throw it away. But the reverse is not reliable: food can smell normal and still have spent too long at an unsafe temperature.

Quick Refrigerator Decision Table

Situation	Decision	What to do
Power out 4 hours or less, door mostly closed	Keepable range	Keep the door closed and let the refrigerator recover.
Power out more than 4 hours, no cold source	Discard first	Start with meat, seafood, eggs, milk, leftovers, and cut produce.
Appliance thermometer shows 40°F or below	Keepable range	Check food condition and keep refrigerated.
Refrigerated food was above 40°F for more than 2 hours	Item-by-item decision	Use the FoodSafety.gov food chart categories below.
Food has odd odor, color, or texture	Discard	Do not taste it. Throw it away.

Refrigerated Foods to Throw Away After More Than 2 Hours Above 40°F

FoodSafety.gov classifies the following refrigerated foods as discard items after they have been held above 40°F for more than 2 hours.

Category	Throw away
Meat and seafood	Raw meat, cooked meat leftovers, poultry, fish, seafood, soy meat substitutes, thawing meat or poultry
Salads, soups, and mixed dishes	Meat, tuna, shrimp, chicken, or egg salad; gravy; stuffing; broth; casseroles; soups; stews
Deli and processed meats	Lunch meat, hot dogs, bacon, sausage, dried beef, refrigerated canned ham, opened canned meat, opened canned fish
Pizza	Any pizza with toppings
Cheese	Soft cheese, shredded cheese, low-fat cheese
Dairy	Milk, cream, sour cream, buttermilk, evaporated milk, yogurt, eggnog, soy milk, opened baby formula
Eggs	Raw eggs, hard-cooked eggs, egg dishes, egg products, custards, puddings, quiche
Produce	Cut fresh fruit, sliced or shredded coconut, cut fresh vegetables, pre-cut or pre-washed packaged greens
Cooked vegetables and starches	Cooked vegetables, cooked tofu, opened vegetable juice, baked potatoes, commercial garlic in oil, potato salad, cooked pasta, cooked rice, cooked potatoes
Sauces and dressings	Fish sauce, oyster sauce, opened creamy dressings, opened spaghetti sauce
Doughs and desserts	Refrigerator biscuits, rolls, cookie dough, fresh pasta, cheesecake, cream-filled pastries, pies or pastries with egg or milk fillings

Opened mayonnaise, tartar sauce, and horseradish have a separate rule in the FoodSafety.gov chart: discard them if they were above 50°F for more than 8 hours.

Refrigerated Foods That May Be Kept

These foods are listed by FoodSafety.gov as keepable after more than 2 hours above 40°F. Still, visible spoilage signs override the table. If the food smells off, looks wrong, or has an unusual texture, discard it.

Category	May be kept
Cheese	Hard cheeses such as cheddar, Colby, Swiss, Parmesan, provolone, and Romano; processed cheese; grated Parmesan or Romano in a can or jar
Fats	Butter, margarine
Fruit	Uncut fresh fruit, opened fruit juice, opened canned fruit, dried fruit, raisins, candied fruit, dates
Spreads and condiments	Peanut butter, jelly, relish, taco sauce, mustard, ketchup, olives, pickles, Worcestershire sauce, soy sauce, barbecue sauce, hoisin sauce, opened vinegar-based dressings
Breads and grains	Bread, rolls, cakes, muffins, quick breads, tortillas, waffles, pancakes, bagels
Pies	Fruit pies
Vegetables	Uncut fresh vegetables, fresh mushrooms, herbs, spices

Freezer Decision Table

Situation	Decision	What to do
Full freezer, door closed, outage under 48 hours	Keepable range	Keep the door closed and let the freezer recover.
Half-full freezer, door closed, outage under 24 hours	Keepable range	Keep the door closed and let the freezer recover.
Food still has ice crystals	Refreeze possible	Refreeze or cook. Expect some quality loss.
Food temperature is 40°F or below	Refreeze or cook	Sort by item and refreeze or cook promptly.
Food was above 40°F for more than 2 hours	Item-by-item decision	Use the frozen food categories below.

Thawed Frozen Food: Refreeze or Throw Away?

Why Smell Is Not the Safety Test

After a power outage, food can look and smell normal even when it should not be eaten. Odor, color, and texture are discard signals, not proof of safety.

That means the rule works in only one direction. If it smells bad, throw it away. If it smells fine, still check the time, temperature, freezer condition, and food category before keeping it.

Tools That Make the Next Outage Easier

The CDC recommends keeping appliance thermometers in both the refrigerator and freezer. The refrigerator target is 40°F or below; the freezer target is 0°F or below. After an outage, those numbers are faster and more reliable than guessing from how cold the container feels.

A simple outage kit can include:

• Refrigerator appliance thermometer
• Freezer appliance thermometer
• Frozen water bottles or gel packs
• Cooler
• Dry ice or block ice if a long outage is expected
• Freezer labels for dates and food names

These tools do not change the safety rules. They help you know whether food actually stayed at 40°F or below and give you a way to keep it there longer.

The 10-Minute Reset After Power Returns

1. Check the appliance thermometer, if you have one.
2. Confirm whether the outage lasted more than 4 hours.
3. Sort perishable refrigerated foods first.
4. For the freezer, note whether it was full or half-full and how long the door stayed closed.
5. Check frozen foods for ice crystals or a temperature of 40°F or below.
6. Bag discarded foods separately and do not put them back in the refrigerator.
7. Separate keepable food into two groups: use soon and refreeze.

If you know the time, start there. If you know the temperature, use it. If both are unclear and the food is perishable, do not make the decision by tasting it.
