Walk into a typical restaurant or supermarket in America, and it is difficult to find meat that resembles animals. Seafood seems to be the exception, as one can easily buy fish, crabs, or lobsters that resemble the animal form in restaurants and supermarkets. Many Americans will feel disgusted to sea a whole pig hanging in a shop, or to find various recognizable animal part in their food, while people in other countries may feel it is normal.
Was this brought from Europe? How long has this attitude about meat existed in America? How did it come about?
