How long do eggs last?

Postby Beardo McShorts » Sat Sep 13, 2014 2:28 pm

I came across this and thought I should post it. It seemed appropriate for this forum. The question is, how long are eggs safe to eat?
The conventional wisdom is between 21-28 days. Apparently thats outdated because of our washing and refrigeration techniques in North America. The current wisdom is that an egg you purchase in the supermarket will last 50 days from the time it is laid. I found this news piece that seems to say that in many countries eggs aren't even washed before you get them. They come complete with chicken shit, etc.

Anyone have any insight on this topic?

There are alot of preppers (and others) that have a different view completely. They don't want to store eggs full of chicken shit and also want to prolong their storage. Their solution has been to wash the eggs and then wipe them with mineral oil. This replenishes the natural coating that keeps them from spoiling. The added bonus is that the mineral oil will last longer.

If you think of an egg as a you would a can of soup, it makes sense that it will last a really long time if you make sure air can't get to it. Thats basically what you are doing when you coat the egg in oil. Making sure that it doesn't absorb any oxygen through the shell.

There was an episode of Doomsday Preppers that actually showed them eating eggs that were 6 to 9 months old.

Pulled from another site, ... long-term/
this mentions that episode of Doomsday Preppers.

Eggs can be stored for up to two to three months at temperatures no higher than 55°F without doing anything to them. However, the humidity needs to be close to 75%. This is an important factor in successful egg storage. If humidity levels are too low, the eggs will dry out. If they are too high, the eggs will get moldy. You want clean, uncracked eggs. If you have to clean an egg before storing it, then put it in the freezer, throw it in the frig for breakfast, or make some deviled eggs with it. The point is, use it elsewhere. Anytime you wash or dry buff an egg, you are removing a protective outer coating which in turn allows bacteria to more easily enter the egg.
What coating the egg with oil does is it seals the shell to prevent evaporation during storage. The eggs you’re going to store this way should be oiled 24 hours after being laid. (This will immediately put store-bought eggs out of the running.) In a clean, closed carton that is located in a cool, dry place, eggs dipped in oil will keep for several months. They will, however, eventually develop an off-flavor, and this off-flavor is especially pronounced in eggs stored at 34°F for more than four months. By the time you hit the six-month mark, the flavor is usually unacceptable to most people.
If you’re able to have fresh eggs at your house day in and day out from some pretty prolific layers, or because you have a neighbor who gives you fresh eggs each day, or if you’re able to obtain fresh eggs from a farmer’s market, then this method may be for you. Regardless, the knowledge alone will be a great help if and when the worst were to happen.
To properly oil your eggs, they must be at room temperature (50 to 70 degrees F) and they must be dry. Make sure your oil is free of bacteria and mold by heating it 180°F for about 20 minutes. Then, with tongs or a slotted spoon, dip the eggs one at the time into the oil. Set them aside on a rack such as is used in candy making and let them drain for about 30 minutes. Pack them away in clean, dry cartons.
The only drawback to storing your eggs in this manner is that once eggs have been oiled, they’re no longer useful for cake making. The oiling interferes with the foaming properties of the egg whites, so they no longer whip up as well as fresh ones do.

Interesting info. Thanks.

There is a comment about green eggs and ham that seems to be appropriate, but I digress. :)
