The egg rule in FDA Egg Safety Rule that is also a federal regulation is designed to prevent foodborne illnesses caused by Salmonella Enteritidis.
The Egg Rule requires that any commercial egg producers that have 3,000 or more laying hens must implement strict on farm prevention as well as testing and refrigeration measures for the eggs.
The requires of the Egg Rule for commercial egg producers requires the eggs to be refrigerated at 45 F or below during transportation and storage starting 36 hours after the eggs are laid.
The Egg Rule also requires that farmers of the eggs must also implement pest control such as for flies and rodents clean poultry and biosecurity plans and hens and their environments are also tested for Salmonella and farmers and producers of the eggs are also required to register with the FDA and also maintain detailed compliance records.
And for people handling these eggs at home, the FDA as well as the USDA also advises people to follow safety practices like refrigeration, cooking the eggs properly and keeping an eye on the shelf life.
The FDA and USDA advises that you should always keep the eggs stored in your refrigerator at or below 40 F and never leave any cooked eggs or dishes that contain eggs out at room temperature for longer than 2 hours.
Also raw eggs will remain safe to use for 3 weeks to 5 weeks from the day you place them in the refrigerator and you should also cook the eggs until both the white and yolk are firm.
Scrambled eggs should be cooked until there are no visible remains.
You can tell when your eggs are bad by cracking them open and if you smell a foul odor or sour or sulfuric odor then the eggs are bad.
If you want to check or tell if the eggs are bad without cracking them open, you can drop the eggs in a bowl of cold water.
When eggs are fresh and good, the eggs will sink to the bottom of the bowl of water.
And when the eggs are bad, the eggs will float to the top of the water.
Eggshells are porous, and so air slowly builds up inside of the eggs over time.
And the more air that is inside the egg, the more the egg will float.
When the egg sinks to the bottom and lays flat, the egg is perfectly flat.
When the egg stands upright at the bottom, the egg is older, but safe to eat and is great for hard boiling.
When the egg floats entirely at the surface, the egg is spoiled and should be thrown out and not cooked or eaten.
Fresh eggs that are cracked open, should also smell mild or even completely odorless.
Bad or spoiled eggs, when cracked open will emit a distinct, pungent sulfur or rotten smell, even after cooking.
If the egg smells bad, throw the egg away.
If it's not smelling bad, you can also tell if the egg is still bad by cracking the egg, and looking closely at the egg to ensure that the egg is healthy and free of bacteria.
When the egg is fresh and safe to eat, the egg yolk, should be round and plump and the white should be thick and stay contained.
When the egg is bad, the egg yolk, will be very flat or break easily and the egg white will be runny and watery.
You should always throw out any eggs that have pink, green, black or iridescent whites.
Also if the egg has slimy or powdery shells they should be thrown out.
You can also use the shake test to check if an egg is bad.
Hold the egg near your ear and then give the egg a gentle shake.
If the egg is fresh and dense, the egg should remain silent.
If the egg has any sloshing or slapping around sound, when you shake the egg, the egg is older and has taken on more air and is likely spoiled and should be thrown out.
