Why It’s Important to Check

Eating bad eggs can cause food poisoning, which can lead to symptoms like nausea, vomiting, and diarrhea. In rare cases, food poisoning from contaminated eggs can cause serious illness and land you in the hospital.

Salmonella is a type of bacteria that can spread to humans through contaminated food, especially eggs and poultry. Symptoms of salmonella poisoning include fever, abdominal cramps, and diarrhea. In severe cases, it can lead to hospitalization or even death.

Pregnant women, young children, and elderly people are particularly vulnerable to the effects of food poisoning. It’s important to seek medical attention if you suspect you have food poisoning from eggs.

The Visual Clues: What to Look for on the Eggshell

One of the easiest ways to tell if an egg is bad is by inspecting its shell. Here are some visual clues to look for on the eggshell:

• Check for cracks, dents, or any other abnormalities on the eggshell.
• Fresher eggs will have a smooth and consistent shell, while older ones may have roughness or spots.
• The color of the eggshell does not determine its freshness, but rather the breed of the hen that laid it.
• Any powdery residue or mold on the eggshell should be a red flag and a sign of spoilage, so ensure you discard any such eggs.
• It’s best to visually inspect the eggshell before purchase or use.

Remember, the eggshell is the first line of defense against bacteria, which is why it’s important to check for any visual clues before consuming an egg.

The Sniff Test

One way to tell is by using your sense of smell. Fresh eggs have a neutral odor, while bad ones may have a sulfur-like or rotten smell. It’s important to trust your sense of smell when determining egg freshness.

Avoid using eggs with a strong or unpleasant odor, as they could be unsafe to consume. The sniff test is a quick and easy way to check for egg freshness. If in doubt, discard the egg and do not use it for cooking or baking.

The Float Test

The float test is a quick and easy way to tell if eggs have gone bad. To perform the test, follow these steps:

Fill a bowl with cold water. Gently place the egg in the water. If the egg sinks to the bottom and lays flat on its side, it’s fresh. If it sinks but stands upright or bobs on the bottom, it’s still safe to eat but probably not as fresh.

If the egg floats to the surface, it’s not fresh and should be discarded.

Note that the float test is not always accurate. Sometimes, fresh eggs may float due to small pockets of air inside the shell, and older eggs may still sink.

The Shake Test: Why a Wobbly Egg May Be Past Its Prime

The shake test is a simple way to check for egg freshness without cracking the egg open. Hold the egg up to your ear and shake it gently to hear how it sounds.

A fresh egg will make little to no sound, while an older egg may slosh around or make noise. If you hear a lot of movement inside the egg or it wobbles a lot, it may be past its prime and should be discarded.

This test is especially useful for checking the freshness of uncracked eggs before cooking or baking with them. However, it’s important to handle the eggs carefully and avoid cracking them when performing the shake test.

How to Tell When Breaking Them

A fresh egg will have a thick and cohesive white, with a bright yellow or orange yolk. When breaking the egg, the white should hold together and not spread too much on the plate or pan. The yolk should be firm but still slightly jiggly, with no signs of discoloration or greenish hue.

On the other hand, older eggs may have a runny or thin white, and a flat or off-centered yolk. These eggs are still safe to eat if they pass the other freshness tests, but may not be as optimal for certain recipes that require good structure and texture.

It’s important to note that even a fresh-looking egg could be bad if it has an off color or unpleasant smell. Always inspect the egg before use, and discard if in doubt or if it shows signs of spoilage. Cracking eggs one at a time can help you identify and discard any bad eggs before they contaminate your dish.

Moreover, inspecting the cracked egg before cooking can also improve the overall quality of the dish. Removing any bits of shell or small blood spots can make a big difference in the presentation and taste of the final product.

Handle raw eggs with care to avoid cross-contamination and follow food safety guidelines when cooking and preparing them.

How to Store Eggs to Keep Them Fresh Longer

Proper storage is essential to extend the freshness and safety of eggs. Consider the following tips:

• Keep your eggs in the refrigerator at a temperature below 40°F (4°C).
• Avoid storing eggs in the door of the refrigerator, even if your fridge has a special compartment for eggs, as the temperature can fluctuate and affect the freshness.
• Keep your eggs in the coldest part of the refrigerator.
• Keep eggs in their original carton to protect them and prevent them from absorbing unwanted odors and flavors from other foods.
• Do not wash eggs before storage, as this can remove the protective outer layer and increase the risk of contamination.
• If you have leftover egg whites or yolks, store them in an airtight container in the refrigerator for up to 4 days.
• Eggs can be stored in the refrigerator for up to 4-5 weeks from the pack date. Be sure to check the carton for the “sell by” or “expiration” date.

Common Myths: Debunking Misconceptions About Egg Freshness

There are many misconceptions about how to determine the freshness of an egg. Here are some common myths, debunked:

Myth #1: The date printed on the carton is always an accurate indicator of egg freshness.

The date on the carton is actually the “sell-by” date, not the expiration date. Eggs are still safe to eat up to 4-5 weeks after the sell-by date, as long as they have been stored properly.

Myth #2: Washing eggs before storage can improve their freshness.

Washing eggs can actually remove the natural protective coating on the eggshell, which increases the risk of contamination from bacteria. It’s best to keep eggs dry until you’re ready to use.

Myth #3: Brown eggs are fresher and more nutritious than white eggs.

The color of the eggshell is determined by the breed of the hen and has no relation to freshness or nutrition. Both brown and white eggs have the same nutritional value.

Myth #4: Eggshells can be reused for cooking or baking.

Eggshells are porous and can absorb unwanted flavors and odors from other foods. It’s best to discard eggshells after use and avoid reusing them in cooking or baking. However, you can use egg shells in gardening.

Tips for Safe Handling and Preparing of Eggs

Proper handling and preparation of eggs is crucial for maintaining food safety and preventing food poisoning. Here are some tips to keep in mind:

• Wash your hands: Always wash your hands before and after handling eggs to prevent the spread of bacteria.
• Avoid cross-contamination: Keep eggs and egg-containing foods separate from other foods, especially those that will not be cooked before consumption.
• Cook eggs thoroughly: Make sure to cook eggs thoroughly to kill any harmful bacteria, including the yolk and white. Avoid consuming eggs that are still runny or have undercooked whites.
• Use pasteurized eggs: For recipes that call for raw or lightly cooked eggs, consider using pasteurized eggs to reduce the risk of foodborne illness.
• Follow best practices: Always follow food safety guidelines and best practices when handling and preparing eggs, including proper refrigeration and storage.
