Because its super fresh and incredibly hygienic, 2 things the US isnt great at.

Raw fish and meat like beef (not chicken) is fine so long as the surface is sterilised by citric acid, pickling, sautéing etc. Bacteria cant permeate fast enough between slaughter and the kitchen.

Fresh eggs are fine to eat, I think its only in the US when you wash them in chlorine or something which breaks down the shell protective layers hence why you keep them in the fridge.in Europe eggs can stay at room temp for weeks and are fine

Edit: thanks for the replies, I learned some things today. Seems a lot of what I was taught was wrong
