How Long Will Food Last In The Fridge If The Power Goes Out?
Losing power is a stressful experience that can leave you worried about your grocery budget and your family's safety. Your refrigerator is designed to keep food cold, but it has limitations once the electricity stops flowing.
Here is a guide to help you navigate food safety during a power outage.
The four hour window
A refrigerator will keep food safely cold for about four hours if the door remains closed. During this initial time, the insulated walls maintain a temperature below 40 degrees Fahrenheit.
Once this four hour mark passes, the internal temperature begins to rise into the danger zone. It's important to keep track of exactly when the power originally went out.
Keep the door closed
The most important thing you can do is avoid opening the fridge door to check on your food. Every time you open the door, you let cold air escape and allow warm air to rush in.
This significantly speeds up the warming process and shortens the life of your perishables. Trust the insulation to do its job during the outage.
The freezer will keep food cold for longer
A freezer will hold its temperature much longer than a refrigerator. A half full freezer can keep its contents frozen for about 24 hours if left closed.
If the freezer is packed to the top, it can stay frozen for up to 48 hours. Keeping items tightly grouped together helps them maintain a colder temperature for a much longer period.
Raw meat
Raw meats are the highest risk items in your kitchen when the power goes out. If meat has been above 40 degrees for more than two hours, it must be discarded.
You should not rely on sight or smell to determine if dangerous bacteria are present. Safety should always come first when dealing with raw animal products after a long power outage.
Dairy and soft cheeses
Milk, cream, sour cream, and soft cheeses like brie or cottage cheese are very sensitive to temperature changes. These items spoil quickly once the fridge warms up.
If the power has been out for more than four hours, these dairy products should go in the trash.
Eggs and egg products
Fresh eggs in their shells can actually last a bit longer than you might expect, but you should still be cautious. If they have been warm for more than two hours, they're risky.
Custards, puddings, and egg-based dressings like mayonnaise must be tossed if the temperature rises. Don't take any chances with eggs during a prolonged power failure.
Fruits and vegetables
Most whole fruits and vegetables are quite hardy and will survive a power outage without many issues. However, pre-cut fruits and bags of leafy greens are different.
Once the protective skin is broken, bacteria can grow much faster in the warmth. If your sliced melon or bagged salad feels warm to the touch, it is time to throw it away.
When in doubt, throw it out
It's painful to throw away expensive groceries, but food poisoning is a much worse outcome. Never taste food to see if it is still good because bacteria that cause illness don't always change the flavor.
If you're unsure about how long the food was warm, the safest path is to discard it.
Clean before restocking
Once the power is back on and you have removed any spoiled items, take a moment to clean. Spilled juices or old odors can linger and contaminate new food.
Use a mixture of baking soda and water to wipe down the shelves and drawers. This give your fresh groceries a clean environment and your have your fridge smelling fresh again.
Dealing with a power outage is difficult, but having a clear plan makes it easier to manage. By following these safety guidelines, you can protect your health and recover quickly.
Staying informed is the best way to handle any household emergency with confidence. Your resilience and preparation will help you get your kitchen back to normal in no time.
