How Long Do Eggs Last in the Fridge – The Ultimate Duration

As an expert in the kitchen, I often get asked, “How long do eggs last in the fridge?” Well, my dear food enthusiasts, I am here to provide you with the ultimate guide on the shelf life of eggs in refrigeration. So, let’s crack open this topic and delve into the details!

The Shelf Life of Eggs: Know Your Numbers

Eggs, being a staple in many kitchens, are known for their versatility and nutritional value. However, they do have an expiration date. When stored correctly in the fridge, eggs can typically last between 4 to 5 weeks past their pack date.
But remember, freshness matters! The longer an egg sits in the fridge, the less fresh it becomes. To ensure you’re using the freshest eggs, it’s essential to understand the pack date and egg grading system.

Understanding Egg Grading and Pack Dates

  1. Egg Grades: Eggs can be classified into three grades – AA, A, and B. The grading is determined by factors such as shell quality, egg white consistency, and yolk integrity. Higher grades indicate superior quality and freshness.
  2. Pack Date: The pack date is stamped on the egg carton and indicates the day the eggs were packaged. It is typically represented as a three-digit number, with the first two digits indicating the day of the year (from 001 to 365) and the last digit representing the specific plant where the eggs were processed.
    Now that we understand the significance of grades and pack dates let’s explore how long each grade of eggs can last in the fridge.

Shelf Life Based on Egg Grades

  1. AA Grade Eggs: With their fresh, firm whites, and bright yolks, AA grade eggs are considered the finest quality. When stored properly in the fridge, AA grade eggs can last up to 5 weeks past the pack date.
  2. A Grade Eggs: A grade eggs are slightly less fresh than AA grade eggs, but they are still of good quality. These eggs can last approximately 4 to 5 weeks past their pack date in the fridge.
  3. B Grade Eggs: B grade eggs, commonly used for commercial or industrial purposes, have a lower quality and freshness level compared to AA and A grade eggs. They are typically recommended for baking or cooking applications where the egg’s appearance is less crucial. B grade eggs can last around 3 to 4 weeks in the refrigerator.

Proper Storage Techniques for Extended Shelf Life

To maximize the shelf life of your eggs, it’s essential to store them correctly. Here are some key storage tips to ensure the longevity of your eggs:

  1. Keep Eggs in their Carton: The carton acts as a protective barrier and prevents moisture loss. It also helps to maintain a consistent temperature, protecting the eggs from picking up odors from other foods in the fridge.
  2. Store Eggs in the Main Shelves: Avoid storing eggs on the fridge door, as this area is subject to temperature fluctuations due to frequent opening and closing. The main shelves provide a stable temperature, extending the overall freshness of the eggs.
  3. Avoid Extreme Temperatures: Eggs are sensitive to temperature changes. Refrigerated eggs should be stored at a consistent temperature between 35°F (1.7°C) and 40°F (4.4°C) to prevent bacterial growth.
  4. Don’t Wash Eggs Before Storage: The protective coating on the eggshell known as the “bloom” prevents bacteria from entering the egg. Washing eggs before storage removes this natural barrier, making the eggs more susceptible to contamination.

Conducting the Freshness Test

In doubt about the freshness of your eggs? Conduct a simple freshness test to ensure your eggs are safe to consume. Follow these steps:

  1. Fill a bowl with cold water.
  2. Carefully place the egg into the water.
  3. Observe the egg’s behavior:
    • Sink and Lay Flat: Fresh eggs will sink to the bottom and lay flat on their side.
    • Stand Upright on One End: As an egg ages, it may start to stand upright on one end but still be safe to consume.
    • Float: If the egg floats to the top, discard it immediately as it has gone bad.


When it comes to egg freshness, proper storage and understanding the grading system are vital. AA and A grade eggs can last up to 4 to 5 weeks past their pack date, while B grade eggs have a shelf life of around 3 to 4 weeks. Remember to conduct the freshness test if you’re unsure about an egg’s quality. By following these guidelines, you can confidently enjoy delicious meals with fresh and safe eggs from your fridge. Happy cooking!
