Full Answer

In most countries outside of the United States, eggs are not refrigerated. In America, regulations indicate that eggs must be power-washed to remove harmful bacteria and other organic matter, which strips the eggs of their natural protective coating. The eggs must be kept refrigerated as protection against potential contamination. If properly refrigerated, fresh eggs should remain healthy to eat for five to six weeks beyond the carton date.
