How to Tell if an Egg is Bad

The Float Test: How to Check If Your Eggs Have Gone Bad

One of the easiest ways to tell if an egg has gone bad is to perform the float test. To do this, simply fill a bowl with water and gently place your egg into the water. If the egg sinks to the bottom and lays flat on its side, it is fresh and safe to eat.

On the other hand, if the egg stands upright on the bottom of the bowl or floats to the surface, it is likely past its prime and should not be consumed. Eggs that float to the top of the water are especially suspect, as this indicates that a significant amount of air has entered the shell, which means the egg has likely gone bad.

It’s worth noting that eggs can still be safe to eat even if they float to the top of the water, but they should be thoroughly cooked before consumption. The float test is a quick and easy way to check the freshness of your eggs before cracking them open.

The Smell Test: Detecting Rotten Eggs with Your Nose

Another way to tell if an egg is bad is to use your sense of smell. When eggs go bad, they emit a sulfuric, rotten odor that is easily detectable. To perform the smell test, simply hold the egg up to your nose and take a whiff.

If the egg smells fresh and clean, it is safe to eat. However, if you detect a foul or pungent odor, the egg has gone bad and should be discarded immediately.

It’s important to note that some eggs may have a slightly sulfurous smell due to the presence of hydrogen sulfide gas. This gas is produced when an egg is cooked at a high temperature or stored for a long period of time, but it doesn’t necessarily mean the egg is bad. If you’re unsure whether an egg is safe to eat based on the smell, it’s best to err on the side of caution and discard it.

The Crack Test: How to Spot Spoiled Eggs Before Breaking Them

If you want to determine whether an egg has gone bad before cracking it open, you can perform the crack test. Simply hold the egg up to your ear and give it a gentle shake. If you hear a sloshing sound, it’s likely that the egg has gone bad and the contents have begun to break down.

Another way to perform the crack test is to examine the eggshell for any cracks, leaks, or discolorations. If the eggshell is intact, smooth, and free of any spots or stains, the egg is likely fresh and safe to eat. However, if the shell is cracked, leaking, or discolored, it’s a sign that the egg has gone bad and should be discarded.

It’s also important to note that eggs should be stored in the refrigerator to keep them fresh and safe to eat for as long as possible. Storing eggs at room temperature can increase the risk of bacterial growth and spoilage, so it’s best to keep them chilled until you’re ready to use them.

The Appearance Test: What to Look for in an Eggshell

You can also use the appearance of the eggshell to determine whether an egg has gone bad. Fresh eggs typically have a smooth, clean shell that is free of cracks or blemishes. On the other hand, eggs that have gone bad may have a dull, rough shell that is discolored or stained.

One thing to look out for is the presence of mold on the eggshell, which is a sign that the egg has definitely gone bad and should be thrown away. You may also notice that the eggshell feels slimy or sticky, which is a sign of bacterial growth and spoilage.

If you’re unsure about the freshness of an egg based on its appearance, you can also perform the float or smell test to be sure. It’s always better to be safe than sorry when it comes to eating eggs, so if you have any doubts about the freshness of an egg, it’s best to discard it.

The Date Test: Understanding Expiration Dates and Sell-By Dates

Most eggs come with a sell-by date or expiration date printed on the carton. These dates can be helpful in determining whether an egg is fresh or past its prime, but they are not foolproof indicators of freshness.

Sell-by dates are used by retailers to indicate how long they should display eggs for sale, while expiration dates indicate the last date the eggs should be consumed for the best quality. However, eggs can still be safe to eat for a few days after the expiration date if they have been properly stored in the refrigerator.

If you’re not sure how long an egg has been in your refrigerator, you can use the date test to determine its freshness. Simply write the purchase or use-by date on the eggshell with a pencil and store it in the refrigerator. This can help you keep track of how long the egg has been in your fridge and ensure that you’re consuming fresh eggs.

Remember to always handle and store eggs safely to minimize the risk of bacterial growth and foodborne illness. Wash your hands before and after handling eggs, store them in the refrigerator, and cook them thoroughly before eating.
