Egg guidance depends on preparation and country. U.S. CDC advice is to cook eggs until yolks and whites are firm, with pasteurized eggs for foods that will not be cooked to a safe temperature. The U.K. NHS makes a specific exception for qualifying hen eggs; that exception is not a worldwide rule for ordinary eggs. CDC table; NHS egg section
