There’s nothing worse than cracking open an egg and discovering it’s gone bad. Whether you’re making breakfast or baking a cake, using expired eggs can ruin your recipe and even pose health risks. But how can you tell if an egg is still fresh or already past its prime? In this guide, we’ll help you understand how to determine whether your eggs are expired or not.

How Long Do Eggs Last?

Eggs are incredibly versatile and popular, which is why many of us keep them stocked in our refrigerators. But it’s important to note that eggs do have a limited lifespan. On average, eggs can last for about 4-5 weeks beyond the date they were laid.

Checking the Expiration Date

The first step in determining whether your eggs are expired is to check the expiration date. Most egg cartons have a “best-by” date printed on them. This date indicates the last day the eggs are guaranteed to be at their peak freshness. However, it’s important to remember that eggs can still be safely consumed after this date, as long as they pass the following tests.

Performing the Float Test

A common method to check an egg’s freshness is the float test. Fill a bowl with water and gently place the egg in it. Fresh eggs that are still good will sink and lay flat on the bottom. If the egg stands upright on the bottom or floats to the top, it is likely past its prime and should be discarded.

Examining the Eggshell

The condition of an egg’s shell can provide valuable insights into its freshness. Gently examine the shell for any visible cracks or leaks. If you spot any, the egg should be discarded, as harmful bacteria could have entered through the compromised shell. Additionally, fresh eggs tend to have a smooth, slightly shiny shell, while the shells of expired eggs may appear dull or rough.

Sniffing for Odors

Eggs that have gone bad often emit a foul odor. If you’re unsure about an egg’s freshness, give it a sniff. Fresh eggs typically have little to no smell, while expired eggs may have a strong, sulfurous odor. Trust your nose, and if it smells off, it’s best to avoid using it.

Cracking Open the Egg

If you’re still unsure about an egg’s freshness, you can perform the final test by cracking it open. Fresh eggs have vibrant, thick egg whites that stay close to the yolk. Expired eggs, on the other hand, might have egg whites that are runny or thin, and the yolk may have a flat appearance.

Storing Eggs Properly

To maximize the freshness and shelf life of your eggs, it’s important to store them correctly. Keep them refrigerated at a consistent temperature below 40°F (4°C). It’s best to store eggs in their original carton, as it provides protection and prevents absorbing odors from other foods in the fridge.

By checking the expiration date, performing the float test, examining the eggshell, sniffing for odors, and cracking open the egg, you can effectively determine whether your eggs are still fresh or expired. Knowing these simple techniques will help you avoid culinary disasters and ensure the safety of your meals. Don’t forget to store your eggs properly to prolong their freshness!
