Power Outage Food and Water Safety on Cape Cod
Published on: September 25, 2026
Strong winds and coastal storms can knock out power on Cape Cod. If the lights go out, one of the first questions is usually:
What about everything in the fridge?
The good news is that you have some time. The most important thing you can do at first is simple:
Keep the refrigerator and freezer doors closed.
And if the power is still on? Even better. There are a few things you can do now to help your food stay cold longer if an outage happens.
Power Still On? Do This Now
A little preparation now can buy you more time later.
- Check the temperature. Your refrigerator should be 40°F or below and your freezer should be 0°F or below.
- Freeze containers or bottles of water and gel packs. They can help keep food cold longer if the power goes out.
- Find your coolers now. Finding the cooler is considerably easier while the lights are on.
- Group frozen foods together. A packed freezer stays cold longer than one with lots of empty space.
- Consider freezing refrigerated foods you will not need right away.
- If you have appliance thermometers, put one in the refrigerator and freezer.
These are steps recommended by CDC to help prepare for a possible power outage.
The Power Went Out. Now What?
First: leave the fridge alone.
We know you want to check it.
And then check it again.
Every time you open the refrigerator or freezer, cold air escapes.
If the doors stay closed:
- A refrigerator can keep food safe for about 4 hours.
- A full freezer can maintain a safe temperature for about 48 hours.
- A half-full freezer can maintain a safe temperature for about 24 hours.
So resist the urge to stand in front of the open refrigerator deciding what you might want for lunch.
Keep. The. Door. Closed.
Has It Been More Than 4 Hours?
If the power has been out for four hours and you have not had another cold source keeping refrigerated food at 40°F or below, it’s time to start checking what needs to go.
Perishable foods that may need to be discarded include:
- Meat, poultry and seafood
- Milk and other perishable dairy products
- Eggs
- Cut fruits and vegetables
- Cooked vegetables
- Leftovers
And one very important rule:
Do not taste food to decide whether it is safe.
Food can contain germs that can make you sick even when it looks or smells normal.
When in doubt, throw it out.
What About the Freezer?
Don’t automatically throw everything away when the power comes back on.
Frozen food can generally be safely refrozen or cooked if it still contains ice crystals or is 40°F or below. The quality may change after refreezing, but the food may still be safe.
Not sure about the chicken? The ice cream? That mystery casserole that’s been in there since who knows when?
The FoodSafety.gov Food Safety During a Power Outage chart provides item-by-item guidance on what should be discarded and what may be safely kept or refrozen.
Did Floodwater Reach Your Food?
Power outages aren’t the only food safety concern during coastal storms.
Food that comes into contact with floodwater or stormwater may be unsafe to eat.
CDC recommends throwing away food that may have contacted floodwater, including foods in packaging that isn’t waterproof. That can include cardboard containers and packages with screw caps, snap lids, twist caps and similar closures.
Don’t judge it by how it looks or smells.
If floodwater reached it and you aren’t sure it’s safe, throw it out.
Cleaning Your Refrigerator After Spoiled Food
Sometimes the power stays out long enough that the refrigerator needs more than a quick wipe-down.
If food spoiled during an outage, remove it and clean the refrigerator before restocking it. Wash removable shelves, drawers and other surfaces with hot, soapy water, rinse with clean water, and follow CDC guidance for sanitizing after spoiled food or floodwater exposure.
The CDC’s Keep Food Safe After a Disaster or Emergency guidance includes detailed cleanup instructions.
Don’t Forget About Drinking Water
Power outages and coastal flooding can also affect access to safe drinking water.
Follow any drinking-water advisories issued by your town or local officials. If officials advise that tap water is unsafe, use bottled water or follow their instructions for making water safe.
If You Have a Private Well
Many Cape Cod homes with private wells rely on electricity to pump water. If the power goes out, your well pump may stop working even if the well itself is fine.
Flooding creates a different concern. Floodwater can contaminate private wells.
If your well has been flooded, do not assume the water is safe just because the power has returned. Follow local health department guidance about testing and disinfecting your well before using the water for drinking or cooking.
Power Outage Food Safety: The Numbers to Remember
Here’s the quick version:
40°F: Refrigerator temperature or below
0°F: Freezer temperature or below
4 hours: Unopened refrigerator
48 hours: Unopened full freezer
24 hours: Unopened half-full freezer
And the easiest number to remember?
0 unnecessary trips into the fridge.
The cheese will still be there when the power comes back.
Print This Before You Need It
Here’s one storm-prep task that requires no ladder, no yard work and no wrestling patio furniture in the wind.
Print something for the fridge.
The CDC has printable food safety resources you can keep handy before an outage happens.
Print one. Stick it on the fridge. Give it a place of honor among the magnets and takeout menus.
Then, if the power goes out, the information you need is already hanging right there. No searching on your phone while your battery and internet connection are also having a rough day.
The CDC’s Keep Food Safe After a Disaster or Emergency page includes printable resources and materials in multiple languages.
Your refrigerator has earned some new artwork.
