Bananas and eggs, actually :)
"Egg grades
Eggs are graded according to their quality. There are three grades: AA, A and B. In our supermarkets we will find grade AA and A eggs. Lower quality grade B eggs are used in the commercially produced foods that we find in our shops and supermarkets.
It is not only the appearance of the shell that is graded, but the contents are also considered too. The eggs pass in front of a special bright light so that the contents of the egg can be seen. "
Additionally, bananas have been graded since the 1970s by the UK government, the EU was simply trying to bring the standards of each grade in line across the whole of the EU, so if you buy a grade2 banana from a supplier in spain it would be the same quality as a grade2 banana brought from a supplier in France, or the UK, or Greece... and so on.
But it did give all the mindless sheep that can't find out there own facts something to be up in arms about as they blindly believed anything published by the UK press.
