Long power outages, heatwaves, natural disasters, or other emergencies can catch you off guard.

In such moments, the main thing is not to panic and to know the basic rules that will help preserve food and avoid food poisoning.
Food safety experts and the American Red Cross emphasize that preparing for a blackout is not just about water and flashlights, but also about proper food supplies and understanding how to store them without refrigeration.
What to have at home in case of a power outage
During emergencies, it is best to create a small emergency supply of food in advance that does not require refrigeration:
-
Canned goods (meat, fish, legumes, vegetables);
-
Dry goods (cereals, pasta, oatmeal);
-
Nuts and dried fruits;
-
Ready-to-eat snacks (crackers, crispbreads);
-
Bottled water.
It is important to choose products that can be consumed without heat treatment or cooking.
How to preserve food during a blackout
If the power goes out unexpectedly, the main rule is to not open the refrigerator unnecessarily. According to experts, a closed refrigerator keeps cold for approximately:
-
up to 4 hours – refrigerator compartment;
-
up to 24–48 hours – freezer compartment (if full).
-
What else will help:
-
Use cold packs or ice – if you have pre-frozen cold elements, place the most perishable foods next to them.
-
Move food to the coldest place – a basement, balcony (in cool weather), or a shaded room can partially replace a refrigerator.
-
Group food items together – tightly packed food items retain cold longer.
What to do with food after a power outage
After a prolonged blackout, it is important to check food safety.
Discard:
-
Meat, poultry, fish that have been without refrigeration for more than 2 hours;
-
Dairy products that have lost their cold;
-
Dishes with mayonnaise, creams;
-
Any food with an unusual smell or color change.
Do not risk it: even if the appearance is normal, bacteria can multiply rapidly.
How to avoid food poisoning
Food safety organizations, including the American Red Cross, advise following simple rules:
-
Do not taste “to check”;
-
Do not leave ready-to-eat food at room temperature for more than 2 hours;
-
Wash hands with clean water;
-
Use only safe bottled water.
How to prepare in advance
To avoid finding yourself in a critical situation, you should:
-
Create a food supply for 3–7 days;
-
Have an insulated bag or cooling elements;
-
Store a supply of water;
-
Regularly update the products in the “emergency kit.”
