Do Eggs Go Bad in the Refrigerator?

Eggs are a staple in many households, celebrated for their versatility and nutritional benefits. However, understanding how to store them properly in the refrigerator ensures they remain fresh and safe to consume. In this guide, we'll explore the factors affecting egg freshness, how long they last in the fridge, and tips for proper egg storage.

How Long Do Eggs Last in the Refrigerator?

Eggs can remain fresh in the refrigerator for an impressive duration, but several factors influence their shelf life:

  • Unwashed Farm-fresh Eggs: These can last approximately 3 to 5 weeks if stored correctly.
  • Washed Store-bought Eggs: These typically have a shelf life of about 3 to 4 weeks. The washing process removes the protective coating, potentially decreasing longevity.

To visualize, see the table below:

Egg Type Storage Method Duration in Refrigerator
Unwashed Farm Eggs In Carton 3-5 weeks
Washed Store Eggs In Carton 3-4 weeks

Factors Affecting Egg Freshness

Temperature Control

For optimal shelf life, keep your refrigerator at or below 40°F (4°C). Maintaining a constant temperature is crucial, as fluctuations can accelerate spoilage.

Storage Method

Utilize the original carton to store eggs. This helps prevent moisture loss and shields them from absorbing strong odors in the refrigerator. Additionally, storing eggs with the pointed end down can help maintain yolk quality.

Signs That Eggs Have Gone Bad

Knowing when eggs have spoiled is essential to prevent foodborne illness. Here are some indicators:

  • Float Test: Submerge an egg in a bowl of water. Fresh eggs sink and lay flat on the bottom, while bad eggs will float.
  • Visual Inspection: Check for cracks or a powdery appearance on the shell. Discard any eggs that look unusual.
  • Smell Test: A sulfur-like or unpleasant odor when cracked open indicates spoilage.

Tips for Maintaining Egg Freshness

  1. Timely Refrigeration: Once purchased or collected, refrigerate eggs promptly to minimize exposure to ambient temperatures.

  2. Avoid Door Storage: The refrigerator door experiences frequent temperature changes, which can affect egg quality. Store eggs on an interior shelf instead.

  3. Check Expiry Dates: While these are guidelines, they can help you track freshness when paired with other visual and sensory checks.

Safe Egg Consumption Practices

Proper cooking ensures that eggs remain safe to eat. Always cook eggs until both the whites and yolks are firm. For dishes like custards, ensure they reach an internal temperature of 160°F (71°C).

Conclusion

By understanding the longevity of eggs and best storage practices, you can extend their freshness and enjoy them safely. Keeping them refrigerated, using the float test to assess freshness, and following safe consumption practices will help you get the most out of your eggs. With these tips, you can ensure that eggs remain a nutritious, long-lasting addition to your diet.
