The Long Term Storage of Fresh Eggs

Over the years, I have read various articles on the internet about methods of storing fresh eggs for extended periods of time without modern refrigeration.  This is a subject that I have seen quite a bit of discussion on ever since Doomsday Preppers appeared on TV.  One of the preppers was shown coating fresh eggs with mineral oil.

I have hesitated to write on this subject since I have until now not preformed any tests or seen any that I trusted.  I recently came across an old article in Mother Earth News from 1977.  In this article, they outline a series of test they performed on both fertile and unfertile eggs.  These are the most reliable tests that I have been able to find.

Unfortunately they did not include mineral oil in there tests.  In the future, I plan to conduct some tests using mineral oil using both washed and unwashed eggs.  If anyone is aware of any test results or have personal experiences with using mineral oil on eggs I would be very interested in having you share the results with the rest of us.

The following is the link to the Mother Earth test performed in 1977  I suggest that you read the article it shows how you can store eggs for up to eight months using various methods.

    Last year I tried the mineral oil test on 2 dozen eggs. I wet a paper towel with usp grade mineral oil and wiped each egg. I placed them in 2 egg cartons and put them on the shelf in the basement. I wrote on the calendar ‘flip eggs’ every month. That way I could remember to turn the eggs every month like I heard you should do. It is pretty easy turning the cartons upside down. After 5 months I started eating the eggs out of the first carton. They were pretty runny and I only made scrambled eggs from them. I don’t think the yolk would hold up anyway and I did not try to boil any because I was afraid of what I might find inside afterward. After the 6 month I started eating eggs out of the second carton. There were three eggs that were bad. You could smell them without breaking them. I threw them in the woods dow wind of the house. The rest were good to eat but did not have the flavor of a fresh egg. The eggs I started with, were from my hens, and they were not fertilized. It is good to know that you can store eggs without refrigeration for a few months…

    I am new to your site but find it informative. I am the editor of a blog about “Essential Stuff”, and wrote a post about long-term storage of eggs (and cheese) in July 2012 ( Specifically, I advise against adding a coating to eggs. Instead, I recommend never washing the eggs with soap before storing (only before using), as the eggs come with a natural protective coating provided by the hen to protect the developing chick. This protective coating is long-lasting and far superior to any coating humans could apply.

    Of course, this only applies to eggs from your own chickens, or from a friend who follows the same advice. It could never apply to commercial eggs because their protective coating has been removed by washing, probably with toxic detergents.

    Mineral oil, paraffin and other petroleum-derived products should NEVER be used on food because the oil is readily absorbed through living membranes. This explains why Marty’s experiment (previous comment) left the eggs runny. Furthermore, petroleum-derived products contain toxins.

    I have read a couple of times, that if eggs are unwashed, it is not necessary to coat them with anything for longer term storage. (the were talking about free range/home farmed eggs/chickens)..They said, that eggs have some sort of natural coating, which will protect them for a long time. This coating is easily washed off, so it is necessary to start with eggs from chickens raised in an environment that the eggs are not being laid into dirty boxes/excretment (as in commercial production).

    in one of these articles I read that it is actually illegal in many European countries to sell eggs which HAVE been washed, as it is believed this will mean the farm / production facilities IS dirty…(don’t know if that is trued)

    regards all this, I recal as a youngster, many farms sold eggs, and these crates of eggs were stored in a porch, with no washing and no refrigeration. Maybe there is something to this “natural” coating theory, if the eggs are unwashed.

    Am sure in the old days, they didn’t worry about washing eggs until they were used. As of today, most people I know that have chickens, wash their eggs before using them. My Aunt always left her eggs in the pantry and washed as needed. Of course that was in the 40’s and 50’s So am sure in case of emergency we can do the same.

    Water glass is the most common and most approved means of storing eggs.
    Maybe this article will help.

    Most of my hen’s fresh eggs that sit after about 2 months in the cartons are either drying up or a few go rotten.

    The “egg” is a perfect storage unit all by itself, designed by nature and “god” if you will, and we just have to respect that, .. lol
    Here is how it was explained to me.
    The hen doesn’t sit on the nest and lay 12 to 14 eggs in a couple of hours and begin to incubate them.
    There’s an awful lot of life and living going into the production of that egg and the poor old hen will be hard pressed to produce one egg a day without taking a break of a day every now and then to keep things balanced and not lay weak eggs.
    It will take her over two weeks to lay all her eggs and the first one laid has to be as “fresh” as the last one laid. Two weeks, … at room temperature.
    Follow me so far?
    So every day the hen lays an egg but before doing so she “fusses” over the eggs already laid in the nest and in her fussing she will turn each and every egg in the nest. Then she’ll lay an egg and wander away to do hen things.
    Never refrigerate your eggs for this natural method of storage, room temperature is fine. Think of the nest and how warm it gets on a regular day. Not too hot, not too cool. (If the hen has a brain at all, and I sometimes wonder)
    So! Take your unwashed eggs, put them in a carton and turn them every day and they will keep for months at porch/room temperature. Just get used to breaking the eggs into a bowl first and then adding to your recipe, just in case eh?
    Just make sure your hens are healthy and have a supply of natural calcium for strong shells.
    This works, I have done it.
    Good luck!
    Oh yeah, look up storing eggs in lime water, … I haven’t tried that one, … yet.
