According to a recent article, Japanese say the best tuna comes from off the coasts of Japan. It is known that Japanese ships are present in the Mediterranean, off the coasts of Sicily, catching many tuna that are flown to Japan daily. The other day, in Italy, information came out that "Sicilian" tuna, actually fished in Sri Lanka, contains an alarming quantity of mercury. So where is the tuna I eat when I am in Japan coming from?
