Infotainment: Shelf life


Q: What is the shelf life of a farm-fresh egg?
A: According to the American Egg Board (, raw eggs can be kept refrigerated for 4 to 5 weeks without much loss of quality. Those weeks start when the egg is created, though—so for grocery store eggs, aim for 3 weeks in your refrigerator. With the farm-fresh eggs in this carton, you get your full 4 to 5 weeks.

Q: What is the shelf life of a hard-boiled egg?
A: Properly refrigerated, hard-boiled eggs keep for 1 week.

Q: Why is the shelf life of a hard-boiled egg less than a raw egg??
A: Hard-boiling an egg removes the bloom from its shell. (Remember the protective bloom?) Therefore, on a microscopic level, the shell is now 'drafty.' Bacteria, off-flavors, and weird refrigerator odors can drift in. So 1 week it is.
