Fresh chicken eggs are a product that everyone has refrigerator, but not everyone knows how to store them correctly. Not only the taste of dishes, but also your health depends on expiration dates: a spoiled egg can cause salmonellosis or other intestinal infections. In this article we will look at how long a raw egg can be stored in the refrigerator depending on the type of packaging, shell processing and temperature, and also learn how to accurately determine freshness.
You will be surprised, but the shelf life of eggs in the refrigerator and at room temperature differ radically - and this is not a myth. It's all about the natural protective shell of the egg and the conditions that we create. For example, in the US, eggs must be washed before being sold, but in Europe they are not, and this directly affects how long they will stay fresh. Next you will find verified data, tables with exact terms and life hacks that will extend the life of the product.
Official standards: How long can eggs last in the fridge according to GOST
In Russia, the shelf life of raw chicken eggs is regulated GOST 31654-2012 and SanPiN 2.3.2.1324-03. According to these documents, the maximum shelf life depends on the category of egg and storage conditions: GOST 31654-2012 from
- 🥚 Dietary eggs (marking “D”) - up to 7 days at temperatures from
0°Cto+20°C. After this period, they are automatically transferred to the canteen category. - 🥚 Table eggs (marking “C”) - up to 25 days at temperature
0°C–+20°C, but no more 90 days when stored in the refrigerator (+2°C–+4°C). - 🥚 Washed eggs (industrial processing) - no more 12 days in the refrigerator, since the protective cuticle the shell is damaged.
Important: these standards apply to intact eggs in original packaging If the shell is cracked or the egg was washed at home, the period is reduced by 2-3 times. Also, the date is often indicated on the packaging. sorting (do not confuse with the production date!), from which the expiration date should be counted.
Table: shelf life of eggs in the refrigerator by type
| Egg type | Storage temperature | Maximum period | Notes |
|---|---|---|---|
| Dietary (labeling “D”) | +2°C–+4°C |
7 days | After 7 days it goes into the canteen category |
| Dining room (marked “C”) | +2°C–+4°C |
90 days | Provided factory packaging and whole shell |
| Washed industrial | +2°C–+4°C |
12 days | The protective layer of the shell has been removed |
| Homemade (unwashed, from the farm) | +2°C–+4°C |
up to 3 months | Subject to storage with the blunt end up |
| Boiled (in shell) | +2°C–+4°C |
7 days | It is better to peel and store in a container |
Please note: in freezer raw eggs in shell cannot be stored - they will burst due to the expansion of the liquid. However, you can freeze beaten eggs (without shells) in airtight containers for up to 12 months.
How to properly store eggs in the refrigerator: 5 key rules
Even if you bought the freshest eggs, improper storage will shorten their shelf life. times. Here's what you need to do:
- Temperature mode: optimal temperature -
+2°C–+4°C. Do not store eggs on the refrigerator door (the temperature fluctuates there when opened) - it is better to use the shelf closer to the back wall. - Position: place the eggs blunt end up. This way the yolk remains in the center and the air chamber is not deformed.
- Packaging: the original cardboard box prevents the absorption of foreign odors and protects from moisture. Do not transfer eggs to plastic containers without a lid.
- Neighbors: keep eggs away from products with a strong odor (fish, onions, spices) - the shell is porous and absorbs aromas.
- Humidity: ideal level -
70–80%. Too dry air accelerates the evaporation of moisture through the shell.
⚠️ Attention: if the egg is cracked, it must be used within 2 days or thrown away. Even in the refrigerator, bacteria penetrate through the cracks, for example, Salmonella enteritidis.
☑️ Checking the egg storage conditions
How to check the freshness of an egg at home: 4 reliable methods
Not sure if the egg is fresh? Don’t take risks - use one of these methods:
1 Test with water (the most. simple)
Pour cold water into a glass and carefully lower the egg:
- 🥚 Sinks and lies on its side - fresh (1-7 days).
- 🥚 Stands vertically at the bottom - edible, but not the first freshness (7-21 days).
- 🥚 Floats - spoiled (the air chamber is too large).
2. Transillumination (ovoscopy)
Bring the egg to a bright light source (can be used flashlight):
- 🔦 Clear yolk, transparent white — fresh.
- 🔦 Vague yolk, cloudy white —old.
- 🔦 Dark spots or blood clots —sign spoilage.
3. Shaking
Bring the egg to your ear and shake:
- 🎵 Nothing you can hear -fresh.
- 🎵 You can hear gurgling gases have accumulated inside, the egg is spoiled.
4. Breaking onto a plate
A fresh egg has:
- 🍳 Dense yolkwhich is not spreads.
- 🍳 Thick proteinsurrounding the yolk.
- 🍳 No foreign odor (rotten, hydrogen sulfide).
⚠️ Attention: if an egg emits when broken hissing sound it is a sign of the beginning of rotting. Such an egg must be thrown away immediately!
Why do eggs spoil even in the refrigerator?
The shell is porous and allows air, moisture and bacteria to pass through. Over time, the white loses moisture, the yolk flattens, and the air chamber increases. If stored incorrectly (for example, on the door), the process is accelerated due to temperature changes.
Is it possible to eat eggs after the expiration date?
There is no definite answer here - it all depends on the storage conditions and the results of the freshness test. Here's what the experts say:
- ✅ Dietary eggs (1-2 days expired) can be consumed if they pass the freshness test (for example, sinking in water). But it is better to use them for baking or frying, and not raw.
- ⚠️ Table eggs (overdue for 1-2 weeks) are permissible to eat only after heat treatment (cooking for at least 10 minutes, frying on both sides).
- ❌ Eggs with cracks or floating in water —it’s absolutely forbidden, even if they “smell normal.” The risk of salmonellosis is too high.
Important: in raw (for example, in eggnog or mayonnaise) you can only use guaranteed fresh eggs - no older than 7 days. For children, pregnant women and the elderly, this period is reduced to 3 days.
What to do if you eat an expired egg: symptoms of poisoning
If you accidentally eat a spoiled egg, monitor your health for a while. 6–72 hours. Typical signs of poisoning:
- 🤢 Nausea and vomiting (starts after 12–48 hours).
- 💩 Diarrhea (often with a greenish tint and a pungent odor).
- 🔥 Fever to
38°C–40°C. - 😵 Dizziness and weakness (due to dehydration).
- 💢 Headache and muscle cramps.
If poisoning is suspected:
- Drink 1–2 liters of water and induce vomiting (if less than 2 hours).
- Take enterosorbents (for example, Polysorb or activated carbon).
- Keep water-salt balance (solution Rehydrona or mineral water without gas).
- At a temperature above
38.5°Cor blood in the stool - consult a doctor immediately.
⚠️ Attention: salmonellosis is especially dangerous for children up to 5 years of age and people with weakened immune systems. Those who consume raw eggs (athletes, adherents of a raw food diet) are also at risk.
Myths and truth about storing eggs: debunking misconceptions
There are many myths around eggs that can harm your health. Let's look at the most common ones: Myth 1: “Eggs in the refrigerator spoil slower than at room temperature.” Eggs are stored in the refrigerator longer, but only if the temperature is stable (
Myth 1: “Eggs spoil slower in the refrigerator than at room temperature.”
❌ Not entirely true. Eggs will last longer in the refrigerator, but only if the temperature is stable (+2°C–+4°C). data-i="245">) they spoil for+20°C–+25°C) they spoil for 7–10 days, but in some countries (for example, Japan) eggs are sold unrefrigerated - thanks to special processing.
Myth 2: “Washing eggs before storage is hygienic”
❌ ErrorWhen washed, the protective layer is removed. cuticle, and the egg becomes vulnerable to bacteria. You need to wash them immediately before use, and not before putting them in the refrigerator.
Myth 3: “Eggs with blood stains are spoiled”
✅ Not always. Blood inclusions (for example, from rupture of capillaries) are an aesthetic defectand not a sign of spoilage. Such eggs can be eaten after heat treatment.
Myth 4: "Eggs are plastic containers last longer."
❌ No. Plastic does not protect against moisture evaporation and odors. Cardboard packaging is more reliable as it absorbs excess moisture and maintains a stable temperature.
Myth 5: “Frozen eggs lose all their beneficial properties”
✅ Partly true. When frozen, some vitamins (for example, vitamin B12) are destroyed, but protein and minerals (calcium, iron) are preserved. Frozen eggs are ideal for baking.
FAQ: Frequently asked questions about storing eggs
