We hear this question a lot. Eggs are a naturally stable item and have a protective film called the “bloom” that helps keep them fresh.
Eggs that are collected daily and are stored under refrigeration with the bloom intact will keep 4-6 weeks. After that, the yolk flattens out and the white thins but the egg is still plenty safe to eat.
So, think of the quality of eggs over time as “fresh” to “less fresh” and not so much “good” to “bad”. Fear not, if it was good enough for an omelet last week, it won’t be a rotten egg next week.
