How Long Do Eggs Last Refrigerated?
Understanding how long eggs last in the refrigerator is crucial for maintaining both their freshness and safety. Proper storage helps extend their shelf life, preventing waste and ensuring that you get the most out of this kitchen staple.
Egg Shelf Life in the Refrigerator
When it comes to storing eggs in the refrigerator, the USDA recommends keeping them at a consistent temperature of 40°F (4°C) or lower. Eggs that are refrigerated promptly and correctly can last for several weeks beyond their sell-by date. Below is a table summarizing the general shelf life of eggs when stored in the refrigerator:
| Egg Type | Refrigerator Shelf Life |
|---|---|
| Raw eggs in shell | 3-5 weeks |
| Raw egg whites | 2-4 days |
| Raw egg yolks | 2-4 days |
| Hard-boiled eggs | 1 week |
| Liquid eggs | 7-10 days if unopened |
| Liquid eggs | 3 days if opened |
Determining Egg Freshness
The Float Test
An easy way to determine egg freshness is the float test. Simply place the egg in a bowl of water:
- Fresh eggs: Sink to the bottom and lay flat on their sides.
- Older eggs: Stand upright or float. These eggs can still be safe to eat if they sink but stand on one end.
Other Signs of Spoilage
- Appearance: Notice any slimy or powdery residue on the shell, which could indicate bacterial or mold growth.
- Smell: A foul odor, either when the shell is intact or upon cracking the egg, is a clear sign of spoilage.
- Texture: An unusually runny consistency of egg white could indicate the egg is past its prime.
Best Practices for Egg Storage
In the Refrigerator
- Keep them in the original carton: The carton protects eggs from absorbing strong odors and flavors, as the shell is porous.
- Do not store in the door: Store eggs on an internal shelf, where the temperature is more stable.
- Check expiration or sell-by dates: While eggs can last beyond these dates, they should be consumed sooner for optimal quality and taste.
Freezing Eggs
Eggs can be frozen to extend their shelf life for up to a year. However, it’s important to note that raw eggs in their shells should not be frozen. Instead, consider the following methods:
- Whisk together eggs: Mix together whites and yolks, then pour into a freezer-safe container.
- Separate whites and yolks: Freeze individually, adding a pinch of salt or sugar to yolks to prevent gelling.
Health Considerations
Why Proper Storage Matters
Eggs are a nutritious, high-protein food that can be susceptible to Salmonella if not stored or cooked properly. Consuming spoiled eggs can lead to foodborne illnesses characterized by symptoms like nausea, vomiting, stomach cramps, and diarrhea. To minimize risks, always prioritize the accurate storage and handling of eggs.
Overall, understanding the longevity of eggs in the refrigerator, paired with safe handling practices, ensures that you get the most nutritional benefit from them without compromising on safety. Implement these guidelines into your routine to keep your eggs fresh, delicious, and safe for consumption.
