Handling eggs safely to prevent Salmonella (1)

Eggs: you may like them sunny side up or over easy, but it's safer to eat eggs that are cooked well. Today some unbroken, clean, fresh shell eggs may contain Salmonella bacteria that can cause foodborne illness. To be safe, eggs must be properly handled, refrigeratedand cooked.

How does Salmonella infect eggs?

Bacteria can be inside an uncracked, whole egg. Contamination of eggs may be due to bacteria within the hen's ovary or oviduct before the shell forms around the yolk and white. Salmonella doesn't make the hen sick. Eggs are washed and sanitized at the processing plant. The Centers for Disease Control estimates that 1 in every 20,000 eggs are contaminated with Salmonella. Persons infected with Salmonella may experience diarrhea, fever, abdominal cramps, headache, nauseaand vomiting.

Who is at risk of illness?

  • Don't wash eggs because you remove the protective mineral oil coating and increase the potential for bacteria on the shell to enter the egg.
  • Use eggs within 4 to 5 weeks from the day they are placed in the refrigerator. The "sell-by" date will usually expire during that length of time, but the eggs are safe to use.
  • Don't keep eggs out of refrigeration. If eggs are left at room temperature for more than 2 hours, throw them out.

Hard-cooked eggs should be safe for everyone to eat. The American Egg Board recommends frying, scrambling, steamingor poaching eggs until both the yolk and the white are firm.

  • Fried eggs -cook 2 to 3 minutes on each side, 4 minutes in a covered pan.
  • Scrambled eggs -cook until firm throughout.
  • Steamed hard cooked eggs with shells - place eggs in a steamer basket of boiling water, steam for 12-17 minutes. Cool under running water. Crack and peel.
  • Poached eggs -5 minutes over boiling water.
  • Soft-cooked eggs -7 minutes in the shell in boiling water.
  • Egg mixtures such as egg bakes, quiches and casseroles are safe if they reach an internal temperature of 160 F.

Serving and storing cooked eggs

Serve your cooked eggs and egg dishes as soon as possible after cooking. If you plan to serve prepared or baked eggs at a later time, refrigerate and use within 3 to 4 days or freeze them for longer storage.

  • Dry meringue shells are safe. So are divinity candy and 7-minute frosting, made by combining hot sugar syrup with beaten egg whites.
  • Avoid icing recipes using uncooked eggs or egg whites.
  • Meringue-topped pies are safe if baked at 350F for about 15 minutes.
  • Chiffon pies and fruit whips made with raw, beaten egg whites are risky. Instead, substitute pasteurized dried egg whites, whipped creamor a whipped topping.
  • To make a recipe safe that specifies using eggs that aren't cooked, heat the eggs in a liquid from the recipe over low heat, stirring constantly, until the mixture reaches 160F. Then combine it with the other ingredients and complete the recipe.
