An older egg may have a flatter yolk and a thinner white. These changes can indicate declining quality, but they do not provide a complete assessment of safety.
If the egg has an unusual odor or other clear signs of spoilage, discard it regardless of the yolk's color.
12. Store Eggs Properly After Bringing Them Home
Choosing good eggs is only half the job. Proper storage helps preserve quality and reduce food-safety risks.
If the eggs are sold refrigerated, take them home promptly and place them in the refrigerator. Keep them in their original carton and follow the temperature and storage instructions supplied by the producer or local food-safety authority.
Avoid repeatedly moving eggs between cold and warm environments. Temperature fluctuations can cause condensation on the shell, potentially increasing the opportunity for microorganisms to move across its surface.
Should eggs be stored in the refrigerator door?
The main body of the refrigerator is generally a better choice because the temperature tends to be more stable than in the door, which warms each time the refrigerator is opened.
Keep eggs away from raw meat and other foods that could contaminate their shells or contents. Wash your hands after handling raw eggs, and clean any surfaces that come into contact with them.
Do not leave cooked eggs or dishes containing eggs at room temperature for long periods. Refrigerate perishable leftovers promptly and follow local food-safety recommendations.
How long do eggs last?
There is no single storage period that applies to every egg in every country. Shelf life depends on processing methods, refrigeration, the condition of the shell, and the producer's instructions.
Use the date on the carton as a guide, but also consider how the eggs have been stored. When in doubt about whether an egg has been handled safely, it is better to be cautious than to rely on appearance alone.
13. Cook Eggs Thoroughly to Reduce Food-Safety Risks
Even eggs that appear fresh and have intact shells can contain harmful bacteria.
Cooking eggs thoroughly is one of the most effective ways to reduce the risk of foodborne illness. The egg white and yolk should be cooked until firm, and mixed egg dishes should be cooked through.
Dishes made with raw or lightly cooked eggs require extra care. Homemade mayonnaise, some desserts, sauces, and uncooked egg drinks may expose people to a higher risk if the eggs are contaminated.
If a recipe requires raw or undercooked eggs, consider using pasteurized eggs or pasteurized egg products and follow the product instructions.
Who should be especially careful?
Young children, older adults, pregnant people, and individuals with weakened immune systems are more likely to experience serious complications from certain foodborne infections.
For these groups, thoroughly cooked eggs are generally the safer option.
Remember that washing the shell, smelling the contents, or checking the egg in water cannot guarantee that it is free from pathogens. Appropriate refrigeration, clean handling, and thorough cooking work together to reduce risk.
14. Common Egg-Buying Myths You Should Stop Believing
Several popular beliefs can make egg shopping more confusing than it needs to be.
Myth 1: Brown eggs are healthier than white eggs.
Shell color is mainly determined by the hen's breed. It does not reliably indicate nutritional value.
Myth 2: A dirty egg is always more natural.
Dirt does not prove that an egg is healthier or comes from a better farm. Excessive contamination can raise hygiene concerns.
Myth 3: A smooth shell means the egg is artificial.
Natural eggs vary in texture. A smooth shell is not evidence that an egg has been manufactured artificially.
Myth 4: A strong smell is the only way to identify a spoiled egg.
Smell can reveal obvious spoilage, but dangerous bacteria may be present without changing an egg's odor or appearance.
Myth 5: Small eggs are always more nutritious.
Small eggs are not automatically richer in nutrients or lower in cholesterol in a way that makes them universally superior.
Myth 6: A floating egg is definitely contaminated.
Floating generally indicates an enlarged air cell and greater age. It does not directly reveal whether harmful bacteria are present.
Myth 7: A darker yolk proves that the egg is healthier.
Yolk color depends largely on pigments in the hen's feed. Color alone cannot establish overall nutritional quality.
Understanding these myths helps shoppers focus on the factors that actually matter: freshness, intact shells, reliable sourcing, proper storage, and safe cooking.
15. A Simple Checklist for Your Next Shopping Trip
You do not need complicated tests or special equipment to make a sensible choice when buying eggs. A few practical habits can help you select good-quality products.
Before purchasing, check the following:
-
Inspect the carton: Make sure it is clean, dry, and not crushed or leaking.
-
Check the shells: Avoid eggs with cracks, leaking contents, or suspicious contamination.
-
Read the label: Look for the packing date, best-before date, storage instructions, and producer information where available.
-
Compare prices fairly: Consider egg size, quantity, production claims, and freshness rather than shell color alone.
-
Choose a reliable seller: Prefer suppliers who handle and store eggs appropriately.
-
Transport them carefully: Avoid leaving eggs in a hot car or exposing them to prolonged heat.
-
Refrigerate when appropriate: Follow the storage instructions for the eggs you purchase.
-
Cook them safely: Avoid consuming raw or undercooked eggs unless appropriate pasteurized products and safe handling practices are used.
These simple steps are more useful than trying to determine quality through shell color, shaking, or touching alone.
Final Thoughts: The Best Egg Is Not Always the Most Expensive One
When choosing eggs, it is easy to be influenced by appearance, price, and traditional advice. Brown eggs may look more rustic, large eggs may appear more substantial, and orange yolks may seem richer. Yet none of these characteristics, on its own, proves that an egg is fresher, safer, or more nutritious.
The best approach is to look at the complete picture.
Choose eggs with intact shells, check the available date and storage information, buy from sellers who handle their products responsibly, and keep the eggs under appropriate conditions after purchase. At home, use clean utensils, wash your hands after handling raw eggs, and cook eggs thoroughly when food safety is a concern.
You can still choose brown eggs if you prefer their appearance, white eggs if they offer better value, or eggs from a particular farm if you trust its practices. There is no need to pay extra simply because a shell has a certain color.
Ultimately, a good egg is one that meets your needs, comes from a reliable source, has been handled properly, and is prepared safely. By understanding the science behind egg quality and avoiding common myths, you can shop with greater confidence and enjoy this everyday food as part of a balanced diet.
