The USDA is every bit as bad as the EU in its enforcement of ridiculous and arbitrary standards to protect vested corporate agricultural interests. Did you know US RDAs are generated to reflect America’s current food production, and bear no relation to actual dietary requirements?
The worst area where these degrades quality is with eggs. In the UK, we use a gentle washing process which doesn’t strip the cuticle from the eggs. One occasionally sees is little bit of embedded filth or a feather on an eggshell, but generally we don’t see a substantial risks of food poisonings from this source.
In the US, your eggs are industrially washed, stripping the cuticle. It means that the eggs can’t stay fresh for much time at all. By the time they reach your supermarket shelves they are already somewhat past their best.
