Keep eggs in the fridge?

Firstly, this post is not about websites

Free range chickens taking a break from egg layingAfter doing a Google search, I realised I’ve never read a scientific response to the question: Should you keep eggs in the fridge?

I remember the “Two Fat Ladies” saying how ridiculous it was that young people put eggs in the fridge. However, I never saw these two as the best people to get advice off, unless I needed to stuff a pheasant or something similar.

The average chicken lays one egg per day. So this is a whole day’s work and should be treated with respect. Luckily, egg storage in the home does seem to have concerned Guardian readers.

Andy P of London in the Notes and Queries section of The Guardian writes “a bad egg is one that has been contaminated with bacteria. Hens lay eggs and the embryonic chicks develop perfectly satisfactorily over a period of 21 days.”.

He continues “Little bacteria gets into the egg, even with an incubation temperature higher than room temperature while the hen sits on it. Eggshells will maintain integrity in room temperature for at least 21 days.

However, at low temperatures (say, in a fridge), the outer mucoprotein cuticle (which behaves like wax) covering the shell dries and shrinks, exposing the some 17,000 pores in the calcium carbonate shell.

This increases the probability of bacterial contamination but only, according to academics, by about 5%. As the cuticle is soluble in water, you shouldn’t wash eggs before storage either. By far the largest contributing factor, however, is the number of bacteria that has access to the egg and, contrary to belief, there is still a large number of bacteria in the fridge.

In summary, keeping your eggs in their box (or a clean porcelain chicken – love it!) is by far the best strategy.”

Thank you Andy P of London, whoever you are.

Next up. What’s best? wrap mushrooms in clingfilm so they sweat or paper bag so they dry out ?
