    Sashimi-Grade

    A designation indicating fish has been frozen to FDA-recommended temperatures (-31°F for 15 hours or -4°F for 7 days) to eliminate parasites, making it safe for raw consumption. Also implies superior freshness and handling.

    In-Depth Explanation

    Despite its widespread use, 'sashimi-grade' is not an official FDA designation — it is an industry term indicating that fish has been handled with the care necessary for raw consumption. This includes proper flash-freezing to kill parasites (required by FDA for all fish served raw except tuna), maintaining an unbroken cold chain from boat to table, and visual inspection for quality. Tuna is the exception to the freezing rule because its flesh is inhospitable to parasites. When purchasing sashimi-grade fish, look for bright color, firm texture, fresh ocean smell, and a reputable supplier who can document their handling and freezing protocols.
