I have to disagree 100% here....I have not seen anyone slap a fish.
Cough or sneeze on it...
Go visit a meat packing or fish handling plant in the USA and then tell me which is grosser....
Sorry but the standards of seafood here are far superior to a good majority of what happens in the USA (some beach places aside) Like bleach with your fish? Dye to cover the fact that it is old? Things shot in the eyes as well so it looks fresh? That sanitizer makes it onto the fish? Oh and gloves do not keep you from picking your nose, scratching your a$$ or getting a long gross hair stuck on top of your food.
Maybe what you are missing is a great fishmonger. Mine wears big plastic yellow gloves. He and his wife remove their gloves to run Credit cards and collect notes. They rinse their hands constantly and go through tons of towels and knives. Heck even Sanisbury's here in Devon is good.
You should always rinse your meat and fish and pat dry at home before you prepare it no matter where you got it from.
Sorry, but I guess I am a bit biased. One thing I love love love about the UK and France and Spain is the fresh fish and the high quality of produce and food. I understand things can gross people out, but just because it comes in a nice little package or because they use sanitizer does not mean that e-coli are absent.
Also I have been at stores late enough to be able to tell you they don't reuse the ice.
If you really are desperate for some decent seafood, pickup a Rick Steins good Food guide.
Or here is a online service
http://www.mstevensandson.co.uk/shop/index.phpThey come highly recommended by Rick Stein and several other chefs as well as out local food magazine.
If one feels the standards are really bad enough to endanger the public then I suggest a call or letter to the place in question would be a good idea as we don't need people keeling over with food poisoning.
