Squirrelling around desperately to find and ridicule examples of arcane EU "rules" (which are generally mythological in any case when examined a bit more closely) is something I thought we'd long ago got out of our systems. EU rules and regulations are generally arrived at by consensus, and the UK has accepted over 95% of them without demur. We've abstained on some of those 5% and opposed very few. You don't achieve agreement and harmony across 28 countries by trying to bring in silly rules. Now being made to import beef pumped up with hormones and chickens still riddled with Salmonella (due to lousy husbandry) even after being washed in chlorine, IS something to worry about.
