Look for any pink, blue, green or black discoloration in the yolk or whites, as this may indicate bacterial growth 3, 4.

The sniff test is the oldest, simplest and most reliable method of telling whether an egg has gone bad.

If anything smells off, toss the egg and wash the bowl or plate with hot, soapy water before using again. Sniffing either a raw or cooked egg is a simple but reliable way to tell if an egg has gone bad.
In addition to your nose, your eyes are a valuable tool for telling whether an egg is good or bad. Sliminess or cracks can indicate the presence of bacteria, while a powdery appearance on the shell may indicate mold 4.

But this does not necessarily mean it has gone bad, and it can still be perfectly fine to use 4. In addition to sniffing an egg, check its shell for signs of bacteria and mold.
Inspecting the whites and yolk for discoloration is also a good strategy. This is also a common method for determining the age of a fertilized egg that is developing into a chick 5 , 6. To perform the float test, gently set your egg into a bowl or bucket of water. If the egg sinks, it is fresh. If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air.
If the air pocket becomes large enough, the egg may float. An egg can sink and still be bad, while an egg that floats may still be fine to eat 3. Checking whether an egg sinks or floats is a popular way to check how fresh it is. Candling is a method used either to assess the quality of a table egg or to assess the development of the chick in a fertilized egg.
This is done industrially using specialized equipment to ensure the proper grading of table eggs before they are packaged. Hold the light source up to the large end of the egg. Then, tilt the egg and turn it quickly from left to right.
