whats the best way to tell if a chicken egg is fresh if no sell buy date?

Answer 1

Put an uncooked egg in plenty of water - if it sinks it is ok
if it floats it is not ok - the insides are going putrid and producing gasses - hence it floats

Answer 2

As an egg gets older, more air gets into the egg and a pocket develops at one end. If you put in in cold water, part of it will float naturally but the more it floats, the older it is. You can also gently shake it. If there is noticable movement the egg is quite old.

The next check is to crack it onto a plate. I really wouldn't recommend this if you know it is more than a couple of weeks old as the smell when eggs go off is basically a stink bomb of sulphur! The smell will take days to clear if done inside. If you crack the egg there will be several signs of freshness. the yolk will be prominent (sitck out a lot) if it is fresh. The white will have two distinct layers; a raised part close to the yolk and a lower, more watery one on the outside (if it is fresh). If the egg is old, the layers will be less distinct.

Personally, I won't eat an egg that is more than two weeks old unless it is being cooked thoroughly and certainly wouldn't risk it if I can't remember when I bought it! Eggs in the UK should now be individually date stamped.

How to tell how old a raw egg is while it is safely tucked away in its shell could seem a bit tricky, but not so. All eggs have an air pocket in them. There is a simple test that tells you exactly how much air there is. All you do is place the egg in a tumbler of cold water: if it sinks to a completely horizontal position, it is very fresh; if it tilts up slightly or to a semi-horizontal position, it could be up to a week old; if it floats into a vertical position, then it is stale. The only reason this test would not work is if the egg had a hairline crack, which would allow more air in. That said, 99 per cent of the time the cook could do this simple test and know precisely how the egg will behave. In my opinion, all eggs should be used within two weeks if at all possible. An extra week is okay, but three weeks is the maximum keeping time.

Answer 4

There is a small air pocket in the large end of the egg. When the egg is fresh, the pocket is only about 1/8th of an inch deep and as large around as a dime. As the egg ages, however, it loses both moisture and carbon dioxide — shrinking — so that the size of the air space increases. And the size of the air space determines the buoyancy of the egg.

So if you submerge a very fresh egg in water, it will lie on the bottom. An egg that is a week or so old will lie on the bottom but bob slightly. An egg that is three weeks or so old will balance on its small end, with the large end reaching for the sky. And a bad egg will float.

Answer 5

The best way is to crack it open and smell it. Usually if any animal product is bad, you'll know right away by smelling it. If it smells okay, (and isn't raw chicken or anything) it's usually safe. However, it's just an egg and eggs are cheap. If there's any serious doubt, just throw them out and buy some new ones. Not worth getting sick over.

Answer 6

because salmonella is a microscopic organism, no, you won't be able to tell even if it really is modern-day in basic terms by technique of searching. Cooking something to a temperature of one hundred sixty F is the purely thanks to be quite certain that any salmonella that could be modern-day is useless, yet maximum folk overcook their food out of panic. definite, there is an chance that you'll be able to fall unwell in the experience that your eggs are slightly runny--although the percentages are surely especially good that in the experience that your eggs were proper saved and dealt with, that you received't.

Answer 7

I think the only way to tell is to crack into a bowl or cup and have a smell of it. The floating in water method is Ok but I still wouldn't risk using it until I had had a look and smell of it out of the shell!

Answer 8

Jusy put it in cold water, if it floats, it is off, if it sinks it is OK. I use this method frequently, as my chickens often lay in out of the way places, and I have no way of knowing how long they have been there

Answer 9

Cover it with plenty of cold water, if it stays on the bottom it's fresh, if it floats to the top, it's rotten.

Answer 10

The shell of a fresh egg should have a matt surface; if it's shiny ot's not fresh. Also float it in cold water; if it sinks, it's fine.If it floats...oh, don't even go there
