The Sushi Economy

The centers of the sushi economy in the twenty-first century are sites of exchange and connection.  Today, the places with the freshest fish — and often, the telltale aroma that draws attention to such privileged locations — are airport cargo hangars and refrigerated storage facilities located near highway interchanges.

That is from the splendid The Sushi Economy: Globalization and the Making of a Modern Delicacy, by Sasha Issenberg.  Most people do not know how much sushi is shipped across borders, and how much the very "freshest" fish has in fact been frozen.
