> keep their eggs in the coolers

This is down to a very specific thing that happens in the USA and doesn't tend to happen here. If you wash an egg (because it has feathers or looks a little "dirty") you remove a sort of protective membrane[0] on the shell's surface which leaves it open to infection. To prevent this you need to refridgerate the eggs.

That said, we do refridgerate eggs in the EU. Every supermarket I've seen in UK and Czech Republic does this, and everyone I know puts their eggs in the fridge when they take them home. It may not be necessary, but we do it nonetheless.

edit: I am now remembering some shops that do have them outside of the refridgerator :D

What? Eggs are not refrigerated in the UK. The tend to sit in the dry goods aisle near the flour and baking products.

The eggs are not refrigerated in every country's supermarkets. Here is The Netherlands they sit on the shelf.

Same in the UK - I've never seen eggs in the fridge at the supermarket.

Where I'm from, eggs are not refrigerated in stores. We do mostly keep them in fridges, except if you get a lot, you put some in the fridge and the rest in the pantry. There is a problem if you store them in the fridge, then put them out, since the condensation may damage the protective membrane.

Reminder that chicks take 21 days to hatch, so a (healthy unfertilized) egg is still safe to eat after 3 weeks in the cupboard.

Eggs are not refrigerated in Switzerland in stores.

I do put my eggs into the fridge but mostly because I don't have much space for them and there is egg store thing int the fridge.

Are you sure that is raw milk in the machines? In my country "fresh milk" is pasteurized. Note that pasteurized milk tastes better than sterilized milk and still needs to be refrigerated.
