Fresh salmon can be safely stored in the refrigerator for approximately two to three days. To maximize its shelf life, store it in the coldest part of your fridge, tightly wrapped or in an airtight container. Always trust your senses; if it develops an off-putting odor, texture, or color, it's time to discard it. For longer storage, consider freezing it in an airtight container or freezer bag, where it can stay good for several months.
