Food code dating expiration codes
Casseroles and dishes containing eggs should be cooked to 160° F as measured by a food thermometer. Once eggs are hard-cooked, they should be refrigerated (in their shells) within 2 hours of cooking and used within a week.Refrigerate them in a clean container, not their original egg carton.After the eggs reach home, refrigerate the eggs in their original carton and place them in the coldest part of the refrigerator, not in the door.For best quality, use eggs within 3 to 5 weeks of the date you purchase them.
Cook eggs thoroughly so both yolks and whites are firm, not runny.
(Source: USDA/FSIS) An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant.
This means the egg is old, but it may be perfectly safe to use.
You'd think it could even be a liability that the consumer has no way of determining how old the product is...
All the same, it would be useful to the consumer to be able to determine when the product was manufactured, so that they can use their best judgement.
