The power went at two in the afternoon. It came back at seven. Now the fridge is humming again, and there is a pot of last night’s daal on the middle shelf that you are not sure about. It smells fine. It looks fine. Load shedding food safety is mostly arithmetic — how many hours, at what temperature — and the honest answer is that smelling it tells you almost nothing.
Here is what the numbers actually say, and where the line falls.
Your fridge buys you about four hours
A refrigerator keeps food safe for roughly four hours after the power goes, according to FoodSafety.gov’s guidance for power outages. A full freezer holds a safe temperature for about 48 hours, or 24 hours if it is only half full.
Every one of those numbers carries the same condition: the door stays shut. A closed fridge is an insulated box slowly warming up. An opened one dumps its cold air on the kitchen floor in seconds, and you do not get it back.
So the four hours is a budget, not a guarantee. Open the door twice to see whether the milk is still cold and you have spent a chunk of it. If a cut is scheduled and you know roughly when it starts, take out everything you will need for the next few hours before it does — then leave the door alone.
The temperature that decides everything is 4°C
Bacteria that cause food poisoning multiply fastest between 4°C and 60°C (40°F to 140°F). That band is why the rules are written the way they are.
Perishable food held above 4°C for more than two hours should be thrown out. And when the surrounding air is above 32°C (90°F), that window shrinks to one hour.
That second number is the one worth remembering here. A kitchen sitting above 32°C in June or July is not unusual, and it quietly halves the time you thought you had. The same pot of daal that would have been borderline in winter is past the line by mid-afternoon in summer, even though nothing about it looks different.
Most load shedding food safety mistakes happen exactly there. The food gives you no signal, so the clock gets ignored.
What has to go
If your fridge was without power for more than four hours, or the food inside sat above 4°C for more than two, these go in the bin:
- Raw and cooked meat, poultry and fish
- Eggs and anything made with them
- Milk, cream, yogurt and lassi
- Soft cheeses
- Cut fruit
- Cooked vegetables
- Cream-filled pastries and mithai made with khoya or cream
Your leftover curry, daal, biryani or haleem sits squarely in this group. They are cooked, perishable dishes and the same clock applies.
One rule matters more than all of these: do not taste it to find out. Food carrying enough bacteria to make you ill can look, smell and taste completely normal. Tasting is not a test — it is just an earlier way of eating it.
What survives without any trouble
Load shedding food safety is not all bad news, and a surprising amount of the fridge is fine:
- Hard cheeses
- Butter
- Peanut butter and jams
- Whole, uncut fruit and vegetables
- Bread and rotis
None of these are in the danger category to begin with. Pulling them out and keeping them somewhere cool and dry during a long cut frees up space and saves you opening the fridge later.
The freezer has one simple test
Frozen food gets a more generous rule. When the power returns, look at each item: if it still has ice crystals and feels as cold as a fridge, you can safely refreeze it. The texture may suffer — refrozen meat weeps, ice cream turns grainy — but it is safe.
If it has fully thawed and been sitting warm, treat it like anything else and throw it out.
Two things make the freezer hold out longer. Keep it full — a packed freezer stays cold roughly twice as long as a half-empty one, which is why filling gaps with bottles of water is worth doing. And keep it closed, for the same reason as the fridge.
Rice is the one that catches people out
Cooked rice left standing at room temperature is among the most common causes of home food poisoning anywhere, and it is the dish most likely to be left out overnight in a Pakistani kitchen. A pot of pulao cooling on the counter through a five-hour cut has been in the danger zone the whole time.
Cool rice quickly, spread out rather than in a deep pot, and refrigerate it within the two-hour window — one hour if the kitchen is hot. If the power is out and it cannot be refrigerated, cook a smaller quantity and finish it.
If you are starting a fresh pot anyway, our guide to cooking basmati rice with separate grains every time covers the soaking and water ratio.
Load shedding food safety starts before the cut
A little preparation removes most of the guesswork:
- Keep a fridge thermometer inside. It costs very little and turns “I think it stayed cold” into a number you can act on. If you come home to an unknown outage, the thermometer is the only honest witness you have.
- Fill freezer gaps with bottles of water. They freeze solid, add thermal mass, and double as drinking water.
- Cook to the day, not to the week, during heavy load-shedding months. Smaller portions mean less to lose.
- Group the perishables together on one shelf so you can move them fast or check them in a single glance.
- Write down when the power went. Four hours is only useful if you know when the clock started, and nobody remembers accurately six hours later.
None of this requires equipment or expense beyond a thermometer. It requires knowing where the line is, and being willing to lose a pot of food when the answer is unclear.
That is the whole of it. When you cannot say for certain how long something sat warm, throw it out. A pot of daal is cheaper than three days off work.
