Refrigerate or Room Temperature
If you buy commercially produced eggs (grocery store) then store eggs in your refrigerator.
If you have hens and do not wash the eggs, then store eggs at room temperature. If storing these eggs in the refrigerator, wash them first.
Why the difference?
Eggs have a natural protective coating – cuticle. It prevents bacteria from entering the egg. This natural protective coating is removed when eggs are washed.
In the United States all commercial eggs are washed and sanitized and must be refrigerated. Refrigerated temperatures at or below 40 degrees Fahrenheit slows the growth of bacteria and helps prevent bacteria from penetrating the shell. Eggs can be stored in the refrigerator for up to 5 weeks.
Unwashed eggs can be stored at room temperature for up to 21 days.
