Facts About Why are eggs in America refrigerated:

Eggs can be kept at room temperature for up to two weeks before becoming bad in most of the world. In contrast, American eggs only have a two-hour shelf life at ambient temperature. It’s merely for cleaning, but a lot of people find that strange and believe that American eggs are unhealthy. America washes eggs to lower the risk of salmonella, which removes the cuticle and necessitates the use of a refrigerator.
