Float Test
The float test is a simple way to check egg freshness without cracking them open. It uses water to reveal how old an egg is. Eggs change over time as air gets inside. This makes them lighter and more likely to float. This test helps avoid bad eggs and food waste.
How To Perform The Float Test
- Fill a bowl with cold water.
- Gently place the egg in the water.
- Watch how the egg behaves in the water.
Interpreting Float Results
If the egg sinks and lies flat on its side, it is very fresh. Fresh eggs have little air inside.
If the egg stands upright but stays at the bottom, it is still safe to eat. It is older but not bad yet.
If the egg floats to the surface, it is bad and should be thrown away. Floating means large air pockets inside.

Crack And Smell Test
The crack and smell test is a simple way to check if eggs are still good to eat. This test reveals signs that eggs might be spoiled. It helps avoid using bad eggs in your meals. Follow these steps carefully to ensure food safety.
Cracking Eggs Safely
Crack eggs on a clean, flat surface. Avoid cracking on the edge of a bowl. This prevents shell pieces from falling inside. Use a separate bowl for cracking eggs. This way, you can inspect the egg before adding it to other ingredients.
Identifying Off Odors
Fresh eggs have little to no smell. A bad egg gives off a strong, sulfur-like odor. This smell is sharp and unpleasant. If you notice this, throw the egg away immediately. Do not try to mask the smell with other ingredients.
Spotting Visual Signs
Look at the egg white and yolk after cracking. Fresh egg whites are thick and slightly cloudy. The yolk should be bright yellow or orange and round. Bad eggs may have pink, green, or iridescent colors. Black or green spots also signal spoilage. Avoid using eggs with these visual signs.
Appearance Clues
Checking an egg’s appearance gives quick clues about its freshness. The color and texture of the yolk and white change as eggs go bad. Careful observation can help avoid using spoiled eggs in your meals. Look closely after cracking the egg open.
Yolk And White Colors
Fresh egg yolks are bright yellow or orange. The white is clear and slightly thick. As eggs age, the yolk may become dull or pale. The white may turn watery or cloudy. A gray or green yolk signals spoilage. Avoid eggs with strange colors.
Unusual Spots And Textures
Watch for black, green, or pink spots inside the egg. These colors show bacterial or mold growth. Slimy or powdery textures on the shell or inside the egg are signs of spoilage. Any unusual texture means the egg is unsafe to eat. Toss eggs with odd spots or textures immediately.
Shelf Life Tips
Keeping eggs fresh is important for taste and safety. Understanding egg shelf life helps reduce waste and keeps meals safe. Simple storage habits and knowing how long eggs last make a big difference.
Follow these tips to store eggs correctly and know their best use period.
Storing Eggs Properly
Keep eggs in their original carton to protect them. The carton stops eggs from absorbing strong smells and moisture. Store eggs in the coldest part of the fridge, not the door. The fridge door opens often and changes temperature. Avoid washing eggs before storage. Washing removes the natural protective layer. Instead, clean eggs just before use if needed.
How Long Eggs Last
Fresh eggs can last three to five weeks in the fridge. Check the date on the carton for guidance. Older eggs may still be safe but test them before use. The float test helps decide if eggs are good. Eggs that sink and lie flat are fresh. Eggs that stand upright are older but safe. Eggs that float should be discarded. Use eggs quickly after cracking, especially if they smell or look off.
Common Myths
Many people believe certain signs always show if eggs are bad. These ideas are common but not always true. Knowing the facts helps avoid wasting good eggs or eating bad ones. Here are two myths explained clearly.
Cloudy Whites And Freshness
Some say cloudy egg whites mean the egg is bad. Actually, cloudiness shows the egg is fresh. It happens because of carbon dioxide inside the egg. Over time, the egg white clears as the gas escapes. Clear whites do not always mean freshness. So, cloudy whites are a good sign, not a bad one.
Green Rings On Yolks
A green ring around the yolk makes people think the egg is spoiled. This color appears when eggs cook too long or cool down slowly. It is caused by a reaction between sulfur and iron in the egg. This green ring is safe to eat. It does not mean the egg is bad or unsafe.

Safety Precautions
Handling eggs safely is key to preventing illness. Eggs can carry bacteria like Salmonella. Taking proper safety steps protects your health. Always check eggs before use. Follow simple rules to avoid eating bad eggs.
When To Discard Eggs
Throw away eggs if the shell is cracked or slimy. Avoid eggs with a bad odor after cracking. Discolored yolks or whites mean spoilage. Also, discard eggs that float in water. These signs show the egg is unsafe to eat.
Avoiding Food Poisoning
Wash hands and surfaces after handling raw eggs. Cook eggs until both yolks and whites are firm. Store eggs in the fridge at or below 40°F (4°C). Keep eggs in their original carton to prevent contamination. Never eat raw or undercooked eggs to stay safe.
