Determining egg freshness can be done easily through physical tests. The most effective method is the water float test. Place an uncracked egg in a bowl of cold water. If the egg sinks and lies flat on the bottom, it is very fresh. If it stands upright on the bottom, it is older but still safe for baking or hard boiling. If the egg floats to the surface, it has built up gas inside and should be discarded.
You can also use the sniff test once you crack the egg. Fresh eggs should have no unpleasant odor. If you detect a sulfur smell, the egg is spoiled and must be thrown away immediately. When cracking eggs, look for firm whites and a yolk that holds its shape well. Cloudiness or a very runny yolk may indicate aging.
Remember that dates printed on cartons often represent peak quality rather than exact safety. The American Egg Board suggests that eggs remain good for four to five weeks after packing. Always store your eggs in the refrigerator below 4°C (40°F) to maintain their quality and reduce the risk of foodborne illnesses like salmonella.
