Eggs should not be stored on the refrigerator door, but in the main body of the refrigerator to ensure that they keep a consistent and cool temperature.
But that’s foreign advice.
In the US, it’s illegal to sell unwashed eggs. In the UK, it’s illegal to sell washed ones. Also, in the UK hens are required to have salmonella vaccinations, not so in the US. (I’m not sure about Canada where that article was printed).
So, due to the salmonella risk and because the washing process affects the shells (it can encourage salmonella to transfer from outside to inside), US eggs need to be stored in the fridge. UK eggs do not have these problems and so should be stored in their box in the cupboard to avoid the chance of them absorbing odours from other strong flavours in the fridge like cheese.
HTH.
