Why do people in the USA refrigerate their eggs, while people in Europe do not?
In the US, eggs are washed. (answer)
FDA regulations require eggs to be washed, which removes the protective "egg bloom" that shields the egg shell pores. The bloom prevents bacteria from getting inside the shell and reduces moisture loss from the egg. Once the bloom is removed, the eggs must be refrigerated so they do not spoil. (explanation)
