Many people find themselves staring at an egg carton in the fridge, unsure if the printed expiration date means the eggs are still safe to eat. For some, this sparks memories of parents using smell or the float test to decide. For others, it may cause kitchen disagreements between cautious spouses and those more willing to stretch shelf life. This common debate reflects broader themes like food safety, rising grocery costs, and generational habits around waste.

Contrary to popular belief, expiration dates on eggs are often just retailer guidelines, not hard rules. When stored properly, eggs can remain fresh for three to five weeks beyond the printed date. Proper storage includes keeping eggs in their original carton and in the coldest part of the fridge—not the door. Still, expiration dates don’t tell the full story, which is why many people rely on old-fashioned methods like the float test and sensory checks.

The float test is a reliable way to determine egg freshness. An egg that sinks and lies flat in water is fresh. If it stands upright, it’s older but still usable. If it floats, it’s no longer good. Cracking an egg onto a plate to check for a firm yolk, thick whites, and lack of odor also helps. Spoiled eggs usually have a strong sulfur smell, even if they appear normal.

While most expired eggs are still safe, eating a spoiled one can lead to foodborne illnesses like salmonella. This is especially dangerous for seniors, who may have weakened immune systems. Symptoms such as nausea, fever, or diarrhea can become serious. If in doubt about an egg’s safety, it’s best to throw it out—especially when someone’s health is at risk.

Ultimately, the key to avoiding waste while staying safe lies in a mix of science, practical wisdom, and communication. Couples with different views on food safety can test eggs together and agree on safe practices. Experts agree: trust your senses, store eggs properly, and cook them to at least 160°F. With the right knowledge and approach, you can make confident, healthy decisions in the kitchen—and keep the peace at home.
