People have strong feelings about food expiration dates—especially when it comes to telling how old eggs are. Some people swear by the date stamped on the side of food products. Others are brave enough to use the date as a rough guideline, give or take a couple of days, maybe even weeks. How long can you, say, keep eggs before they go bad? You find yourself turning to Google for answers to questions like, ”Will I get sick if I eat eggs two days past the expiration date? One week? A month?” Bread is easy, just look for mold. Milk, even easier. The sour smell, or worse, taste, of spoiled milk will stick with you for hours.
Eggs are a bit more difficult. There won’t be greyish-green growths on the shell, or unpleasant odors strong enough to trigger your gag reflex. The fresher the egg, the more intact the white is, but that’s no real way to distinguish whether or not your egg belongs in your frying pan or your trash can. A good way to test the edibility of eggs is to drop them into a glass of water. If the egg sinks, it’s still ok to eat. If it floats, throw it away. It’s as simple as that.
