Egg-cellent Tips: How to Tell if Eggs Have Gone Bad

Eggs are a staple in many households, and for good reason. They are versatile, nutritious, and easy to prepare. However, one of the challenges with using eggs is knowing when they have gone bad. Eating spoiled eggs can lead to food poisoning, which can cause symptoms like diarrhea, vomiting, and fever. Therefore, it’s important to know how to tell if your eggs have gone bad and how to keep them fresh.

The first thing to check is the sell-by date. While this may seem obvious, it’s still worth noting. Always check the expiration date on the egg carton before buying or using them. This will give you an idea of how fresh the eggs are and when they may go bad.

Next, do a visual inspection. Check the eggs in the carton for cracks, and discard any that are damaged. A slimy or powdery substance on the shell is also a sign of potential contamination. Once you crack open an egg, look for signs of decay and any pink or green discoloration. If you see either, it’s time to toss the egg. However, a hard-boiled egg with a green ring is safe to eat.

Another way to check if your eggs are fresh is by performing a float test. In theory, fresh eggs sink, and bad eggs float. As eggs age, a small air pocket inside grows larger, causing older eggs to float. To try the float test, fill a bowl with cold water and add the eggs. If the eggs sink or lay flat, they’re still fresh. If they float, they are no longer fresh and should be discarded.

You can also perform a sniff test. Bad eggs will have a distinct smell, so crack the egg into a bowl and give it a whiff. An egg that has gone bad will have a foul odor or a sulfuric smell. If it has a rotten egg smell, throw it in the trash.

Storing your eggs properly is also key to keeping them fresh. The best way to store eggs and prevent bacterial growth is to refrigerate them properly. Place the eggs in the coldest part of your refrigerator and try to eat them within three to five weeks of purchasing them. Always check the egg carton expiration date to verify the egg’s freshness.

Lastly, never leave refrigerated eggs out on the counter for more than two hours. Eggs can sweat, which creates an environment for bacterial growth.
