Sorry, but that doesn't make sense to me, why would the quality of food there decrease?
Because currently the USDA and FDA equivalents in EU actually work, and the laws that require food inspections are stricter. The worry is that TTIP market access policies will force uniform, lowest-common-denominator rules, eliminating european food QA policies.
TLDR: European regulations force more stringent regulations on producers of eggs; therefore eggs are cleaner and you can store them for weeks without refrigeration.
IMHO they've also got a much nicer colour.
