How Long Are Eggs Good for After Best By Date?

Understanding the Best By Date Label on Egg Cartons

The Best By date label on egg cartons is an estimation of how long the eggs will remain fresh and of high quality. It is important to note that this label is not an expiration date and that eggs can still be safe to consume beyond this date if properly stored and handled.

The Best By date is typically stamped on the carton and can be found near the sell-by date or the Julian date. The Julian date is a three-digit number that represents the day of the year that the eggs were packaged.

When purchasing eggs, it is important to check the Best By date to ensure that the eggs will remain fresh for the desired length of time. It is recommended to use eggs within 3-5 weeks of the Best By date for best quality.

It is important to note that the Best By date is just an estimate and that egg freshness can vary depending on factors such as storage conditions and the age of the eggs at the time of purchase. It is always a good practice to perform the float test to check egg freshness before consuming eggs that are past the Best By date.

Factors That Affect Egg Freshness and Shelf Life

Several factors can affect the freshness and shelf life of eggs, including storage conditions, handling, and age.

One of the most important factors that affect egg freshness is storage conditions. Eggs should be stored in their original carton in the main body of the refrigerator, not in the door. The temperature inside the refrigerator should be kept at or below 40°F (4°C) to prevent the growth of harmful bacteria that can cause spoilage.

Another important factor is handling. Eggs should be handled with care to prevent cracking or breaking, as this can increase the risk of bacterial contamination. Eggs should also be washed before use to remove any dirt or debris.

The age of the eggs can also affect their freshness and shelf life. Fresh eggs will have a thick, firm white and a high, round yolk. As eggs age, the white becomes thinner and the yolk becomes flatter. While older eggs may still be safe to eat, they may not be as fresh or flavorful.

Other factors that can affect egg freshness include the breed of the chicken, the time of year the eggs were laid, and the way the eggs were processed and packaged. By properly storing and handling eggs, and by using them within the recommended timeframe, you can ensure that they remain fresh and safe to eat.

How to Perform the Float Test to Check Egg Freshness

The float test is a simple and easy way to check the freshness of eggs. To perform the float test, fill a bowl with cold water and gently place an egg in the water. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg stands upright on the bottom or floats to the top, it is not as fresh but may still be safe to eat.

As eggs age, the air cell inside the egg grows larger, causing the egg to become less dense and more buoyant. This is why older eggs will float while fresh eggs will sink.

It is important to note that the float test is not foolproof and should not be the only method used to determine egg freshness. If an egg floats, it may still be safe to eat but may not be as fresh or flavorful as a fresh egg. Additionally, if an egg sinks, it does not necessarily mean that it is free from bacteria or other contaminants.

If you are unsure about the freshness of an egg, or if it has been stored for an extended period of time, it is recommended to discard it to be on the safe side.

Proper Storage Techniques to Extend Egg Shelf Life

Proper storage techniques can help extend the shelf life of eggs and keep them fresh for a longer period of time. Here are some tips for storing eggs:

  1. Keep eggs in their original carton: The carton protects the eggs and helps prevent moisture loss.

  2. Store eggs in the refrigerator: Eggs should be stored in the main body of the refrigerator, not in the door, where the temperature is less stable.

  3. Keep the refrigerator temperature at or below 40°F (4°C): This temperature helps prevent the growth of harmful bacteria that can cause spoilage.

  4. Do not wash eggs before storing: Washing eggs can remove the protective coating on the shell, making them more susceptible to contamination.

  5. Use older eggs for baking and hard-boiling: Eggs that are closer to their Best By date are better suited for baking and hard-boiling, as they are easier to peel.

  6. Label the carton with the date the eggs were purchased: This can help you keep track of the age of the eggs and use them before they become too old.

By following these storage techniques, you can help extend the shelf life of eggs and ensure that they remain fresh and safe to eat.

Signs That Eggs Have Spoiled and Should Be Discarded

Eggs that have spoiled can pose a risk of foodborne illness if consumed. Here are some signs to look for to determine if eggs have spoiled:

  1. Foul odor: Spoiled eggs will have a noticeable foul odor, often described as a sulfur-like or rotten smell.

  2. Discolored shell: The shell of a spoiled egg may be discolored, with a greenish or blackish appearance.

  3. Cracked or leaking shell: A cracked or leaking shell can allow bacteria to enter the egg and cause spoilage.

  4. Runny or cloudy egg white: Fresh egg whites should be clear and runny, while spoiled egg whites may appear cloudy and thick.

  5. Strange texture: A spoiled egg may have a slimy or sticky texture.

If you notice any of these signs, it is best to discard the egg to avoid the risk of foodborne illness. It is important to note that some bacteria that cause foodborne illness, such as Salmonella, may not cause noticeable changes in the appearance or odor of an egg, which is why it is important to always follow safe food handling practices when preparing and consuming eggs.
