Of course, fresh is best, but is there an issue with older eggs that are still good? Technically no, you can still eat eggs that aren’t rotten, and it’s always a shame to waste food. However, eggs deteriorate over time, and lose moisture and carbon dioxide, which makes the yolks more breakable and the whites runnier. Plus, older eggs pose a greater risk of food-borne illnesses.

Eggs are a staple in many households. They are versatile sources of protein suited for any meal. They could be scrambled, fried, poached, baked, etc. and paired with an assortment of other foods. However, the expiration date on egg cartons isn’t as clear-cut as the dates on other items. There’s an additional code on an egg carton called the Julian date. Once you decode it, you can ensure you are purchasing fresh eggs.

You can find this code on the side of the egg carton, near the sell by date. It looks like a three digit serial number but it’s actually a date. If you are unfamiliar, Julian dates range from 001 to 365, counting every day of the year, one at a time. For example, 001 is January 1st and 365 is December 31.
