Eggs are a staple ingredient in many recipes, from breakfast classics to baked goods and savory dishes. However, determining the freshness of eggs can sometimes be challenging, especially if they’ve been sitting in your refrigerator for a while. In this guide, we’ll explore easy and reliable methods for assessing egg freshness, ensuring that you use only the best-quality eggs in your culinary creations.

Importance of Checking Egg Freshness

Avoiding Foodborne Illness

  • Consuming spoiled or rotten eggs can lead to food poisoning caused by bacteria such as Salmonella. Checking egg freshness helps prevent the risk of foodborne illness and ensures food safety.

Optimal Taste and Texture

  • Fresh eggs contribute to the taste, texture, and overall quality of dishes. Using stale or bad eggs can negatively impact the flavor and consistency of your recipes.

Reducing Food Waste

  • By identifying bad eggs early, you can avoid using them in cooking and prevent unnecessary food waste. Proper egg storage and periodic freshness checks help maximize the shelf life of eggs and minimize waste.

Methods for Checking Egg Freshness

1. The Water Test

  • Procedure: Fill a bowl or glass with water and carefully place the egg inside.
  • Interpretation:
    • Fresh Eggs: Fresh eggs sink and lay flat on the bottom of the container.
    • Slightly Older Eggs: Eggs that tilt slightly or stand upright on the bottom may still be safe to eat but are not as fresh.
    • Bad Eggs: Spoiled eggs float to the surface of the water and should be discarded immediately.

2. The Candling Method

  • Procedure: Hold the egg up to a bright light source, such as a flashlight or candle, and examine it closely.
  • Interpretation:
    • Fresh Eggs: Fresh eggs have a clear, translucent appearance with a well-defined yolk and white.
    • Older Eggs: Slightly older eggs may exhibit some cloudiness or dark spots, but the contents remain mostly clear.
    • Bad Eggs: Spoiled eggs may appear opaque, cloudy, or have visible discoloration. Cracks or leaks may also be evident.

3. The Sniff Test

  • Procedure: Crack the egg open onto a clean plate or bowl and give it a sniff.
  • Interpretation:
    • Fresh Eggs: Fresh eggs have a neutral or mild odor.
    • Older Eggs: Slightly older eggs may have a slightly sulfuric or eggy smell, but it should not be overpowering.
    • Bad Eggs: Spoiled eggs emit a strong, unpleasant odor resembling sulfur or rotten eggs. If in doubt, discard the egg immediately.

4. The Shake Test

  • Procedure: Hold the egg close to your ear and gently shake it.
  • Interpretation:
    • Fresh Eggs: Fresh eggs produce minimal sound or sloshing when shaken.
    • Older Eggs: Slightly older eggs may produce a faint sloshing sound due to the movement of the contents.
    • Bad Eggs: Spoiled eggs may produce a noticeable sloshing sound or sound hollow due to increased air inside the shell.

Tips for Preserving Egg Freshness

Proper Storage

  • Store eggs in their original carton in the refrigerator, ideally on a shelf rather than in the door where temperatures fluctuate.
  • Keep eggs away from strong-smelling foods, as they can absorb odors and affect their flavor.

Use-By Date

  • Check the expiration or use-by date printed on the egg carton and use eggs before the indicated date for optimal freshness.
  • Eggs are usually safe to consume for 3-5 weeks after the purchase date, depending on storage conditions.

Handling and Preparation

  • Wash hands thoroughly before and after handling eggs to prevent cross-contamination.
  • Avoid cracking eggs directly into food or dishes to prevent the spread of bacteria. Instead, crack eggs into a separate bowl before adding them to recipes.


Checking egg freshness is a simple yet crucial step in ensuring food safety, taste, and quality in your cooking. By employing methods such as the water test, candling, sniff test, and shake test, you can easily assess the freshness of eggs before use. Additionally, proper storage, handling, and adherence to expiration dates help preserve egg freshness and minimize the risk of foodborne illness. By incorporating these practices into your culinary routine, you can enjoy the benefits of fresh, flavorful eggs in your favorite recipes while promoting food safety and reducing food waste.
