Preparing sashimi at home starts with careful handling, not complicated equipment. Keep the fish cold from the moment you bring it home, use clean hands and surfaces, and serve it soon after cutting. These habits help limit opportunities for harmful bacteria to grow or spread. Raw fish still carries risks, and no home handling method can make it risk-free. Choose fish intended for raw consumption, follow the seller’s storage guidance, and use these practical steps to handle it with care.
Keep Fish Cold
Refrigerate sashimi fish as soon as you get home. Keep it in its original packaging or a clean, covered container on a low shelf, where drips cannot reach ready-to-eat foods. Your refrigerator should be at 40°F or below. If you are unsure whether it is cold enough, check with an appliance thermometer.
Take out only the amount you plan to prepare, and leave the rest refrigerated. If the fish is frozen, thaw it in the refrigerator in a leakproof container rather than on the counter. Keep raw fish separate from cooked foods and ingredients that will not be cooked, and wash your hands after handling its packaging or juices.
Clean Your Prep Area
Before cutting, wash your hands with soap and warm water. Clean the counter, cutting board, knife, and serving plate with hot, soapy water, then rinse and air-dry or use a clean towel. A sanitized board can add protection, but it does not replace washing away food residue first.
Use a dedicated clean board and knife for the fish, or wash them thoroughly before switching from other ingredients. Keep raw fish and its juices away from produce, cooked foods, and clean utensils. If your hands touch your phone, trash, or another unclean surface, wash them again before handling the fish.
Cut and Serve Promptly
Prepare sashimi shortly before serving. Work with a small portion at a time and return any fish you are not actively cutting to the refrigerator. Arrange the slices on a chilled, clean plate if convenient, and avoid leaving the platter out while guests eat or while you finish other meal preparations.
As a general food-safety rule, do not leave perishable food at room temperature for more than two hours, or more than one hour when the temperature is above 90°F. Discard sashimi left out longer than those limits. Do not rely on smell or appearance to determine whether raw fish is safe; harmful bacteria may not change either.
Choose Fish Carefully
Ask your fish seller whether the product is intended to be eaten raw and how it should be stored. Terms such as “sushi-grade” are not a guarantee that fish is free of parasites or bacteria. Follow the seller’s handling instructions, keep the fish cold during transport, and head home promptly rather than leaving it in a warm car.
People at higher risk of severe foodborne illness—including pregnant people, young children, older adults, and people with weakened immune systems—should avoid raw or undercooked fish. Cooking fish thoroughly is the safer choice for them. If you have questions about a specific product, ask the seller before serving it raw.
Cold storage, clean preparation, and prompt serving are the essentials of handling sashimi at home. Buy fish intended for raw consumption, follow its storage guidance, and discard it if it has been left out too long.
