Check the expiration or “sell by” date on the carton
Do a water test: place the egg in a bowl of water
If it sinks and lays flat: likely fresh
If it sinks but stands upright: use soon (not ideal)
If it floats: discard
Crack it into a separate bowl before using
If you see an unusual color, cloudiness, or any mold: discard
Smell it after cracking
If it smells bad or sulfur-like: discard
Inspect the shell for cracks or leaks
If the shell is cracked, leaking, or slimy: discard
If stored properly in the refrigerator, use within about 3–5 weeks of purchase (even if past the “sell by” date)
