Egg Safety

Easter is right around the corner and we often get calls about using eggs safely. Here are the answers to some questions regarding eggs that we often get asked.

  • What do the dates on egg cartons mean? The dates on egg cartons help the stores to know which cartons are older and which ones are newer. The recommendation is to use the eggs within 3-5 weeks after bringing them home from the store. This time will often be beyond the date on the carton. The best way to tell if an egg is bad is to crack it in a cup and smell it before using. A bad egg will have a definite odor whether it is raw or hard boiled.
  • How long can you keep hard boiled eggs? You should refrigerate hard boiled eggs within two hours of cooking them and use them within a week.
  • Can raw eggs be used in recipes? The only egg that you can use in a recipe Eggs2where the egg is not cooked would be a pasteurized egg. Many grocery stores now sell shell eggs that have been heated to a temperature that kills bacteria. These are found in a carton that states that they are pasteurized. Many times the eggs will have a P stamped on them indicating they are pasteurized. Liquid eggs are also pasteurized and can be used in recipes where the eggs are not cooked.
  • Can you pasteurize eggs at home? The equipment that pasteurizes eggs is not available for home use. There is a very fine line to cooking them long enough to kill bacteria without cooking the contents of the egg.
  • Is a brown egg more nutritious than a white one? The breed of the hen determines that color of the egg shell. Nutrient levels are not significantly different in white or brown eggs.
  • What does it mean If an egg floats? Just because an egg floats in water when you are boiling them does not mean that it is unsafe. As an egg gets older the air cell enlarges making it more buoyant.
  • Why are some hard boiled eggs harder to peel? A fresh egg is hard to peel. The air cell that is found at the larger end of the egg increases in size the longer the egg is stored. As the contents contract and the air cell increases the shell becomes easier to peel. So if you have eggs that are older use those to hard boil to make peeling easier.
  • What temperature do I need to cook my egg dishes to ensure they are safe? To make sure your egg dishes are safe use a food thermometer and make sure it is cooked to 160° F in the middle of the dish.
  • Are Easter eggs safe to eat? Be sure that dyed eggs are returned to the refrigerator within 2 hours of coloring them. Also use a food-safe coloring so that if is it absorbed through the shell it is safe to eat the egg. Do not hide hard boiled eggs where bacteria can contaminate them. That includes in the dirt outside or where pets can find them.
  • Should eggs be stored in the refrigerator door? It is not recommended that eggs be stored in the refrigerator door. When a refrigerator door is opened the foods stored in the door tend to warm up faster than foods stored in the inside. Store your eggs in the carton and put them in the coldest part of the refrigerator.
  • Can you eat eggs that are cracked? Check your eggs at the store and then again when you bring them home. If an egg has cracked on the way home from the store remove it from the shell and put it in a tightly covered container in the refrigerator and use it within 2 days. Eggs that crack while you are boiling them are safe to eat. Don’t buy cracked eggs from the store.
