Check the expiration or “use by” date on the carton
Perform a smell test when you crack the egg open
Do a water test: place in a bowl of water
If the egg sinks and lies flat, it’s likely fresh
If the egg sinks but stands upright, use soon
If the egg floats, discard
Inspect the shell for cracks, leaks, or unusual slime
Check for off-colors (e.g., pink, green, or mold) in the whites or yolk
If the whites are watery and the yolk is broken or abnormally discolored, discard
If the egg smells sulfurous or “rotten,” discard
Discard if the egg has been left out at room temperature for more than 2 hours (or more than 1 hour if above 90°F/32°C)
