Salmon can typically stay fresh in the refrigerator for up to two to three days if properly stored. It's important to keep the salmon tightly wrapped or in an airtight container to prevent it from drying out or absorbing odors from other foods in the fridge.
Additionally, if you have purchased fresh salmon, it's best to consume it within a day or two for optimal freshness. If you're not planning to use it within that time frame, you can freeze it to extend its shelf life. When freezing salmon, make sure to wrap it tightly in plastic wrap or aluminum foil and place it in a freezer-safe container or bag to prevent freezer burn.
Always check for any signs of spoilage, such as a strong fishy odor, slimy texture, or discoloration, before consuming salmon or any other seafood. If you notice any of these signs, it's best to discard the salmon to avoid the risk of foodborne illness.
