Fresh fish needs steady cold storage from the market to your kitchen. A few simple steps can help protect its quality and reduce the risk of foodborne illness: bring it home promptly, keep it separate from ready-to-eat foods, and cook or freeze it within a short window. Use the guidance below as a practical routine, and follow any specific storage advice provided for the fish you buy.
Get Fish Home Quickly
Plan your fish purchase near the end of your shopping trip. Take it straight home rather than leaving it in a warm car or at room temperature. If you have a longer journey, use an insulated cooler with ice packs and keep the package away from direct sun. Once home, put the fish in the refrigerator without delay.
Keep fish in its original wrapping if it is clean and leakproof. Place the package on a tray or in a shallow container to catch drips, and store it on the lowest refrigerator shelf. This helps prevent liquid from contacting produce or cooked foods. Wash your hands after handling the package.
Keep It Cold
Set your refrigerator to 40°F (4°C) or below and check the temperature with an appliance thermometer if you are unsure. Store fish toward the back of a shelf, where temperatures tend to stay more consistent, rather than in the door. Keep it covered and separate from foods that will be eaten without further cooking.
If the fish is packed with ice, keep the container contained so meltwater cannot spill onto other food. Replace or drain the ice as needed while preserving the sealed wrapping. Do not rinse raw fish in the sink; splashes can spread germs to nearby surfaces. Pat it dry with a clean paper towel just before cooking if needed.
Use It Soon or Freeze It
For best quality, cook fresh fish within one to two days of purchase. If you will not use it in that time, freeze it promptly. Keep track of when you bought or froze it, and follow any handling or use-by guidance provided by the seller. When in doubt about how long it has been stored, do not taste it to check whether it is safe.
To freeze fish, wrap it tightly in moisture-resistant packaging, press out excess air, and label the package with the date and type of fish. Place it in a freezer set to 0°F (-18°C) or below. Thaw fish in the refrigerator, in a sealed bag under cold running water, or in the microwave if you will cook it immediately. Never thaw it on the counter.
Handle It Cleanly
Use a clean board and utensils for raw fish, and keep them apart from equipment used for salads, bread, or cooked food. Wash your hands with soap and water before and after handling it. Clean worktops, knives, and boards with hot, soapy water after preparation, then sanitize surfaces when appropriate.
Cook fish until it reaches 145°F (63°C) at its thickest point, or until it is opaque and separates easily with a fork. Refrigerate cooked fish within two hours, using a covered container. If the room is hotter than 90°F (32°C), refrigerate it within one hour. Keep raw and cooked fish separate throughout preparation and storage.
A reliable routine is simple: keep fish cold, contain any drips, handle it with clean tools, and cook it within one to two days or freeze it sooner. If you have questions about a particular purchase, ask Newcastle Freshwater Fish for storage guidance when you shop.
