A traditional Japanese food made of raw fish, usually wrapped in a soft rice shell. Some raw fish contain adults or larvae of the nematodes of the family Anisakidae. In order to prevent these organisms from infecting persons who eat raw fish, the U.S. Food and Drug Administration has directed that prior to serving, the fish must be suddenly frozen to -31°F (-34.4°C) or below for 15 hr, or held in a commercial freezer at -4°F (-20°C) for 24 hr. After that period, the fish may be thawed and served.See: anisakiasis
