Storage conditions

You should always store your salmon at or below 40 degrees Fahrenheit. Bacterial growth takes place at a faster pace between 40 and 140 degrees Fahrenheit therefore it is always advised to store your salmon at a lower temperature to preserve its freshness and quality for a long time.

You should never let your salmon sit out for more than 2 hours. Salmon lasts for about 2 hours when kept at room temperature. You should discard the salmon that has been left in open for more than 2 hours as bacterial growth takes place at a faster pace between the temperature of 40°F and 140°F, therefore there are greater chances of the salmon being already contaminated with bacteria when left out for more than 2 hours at the room temperature.

It is advised to always store the salmon on the shelf of the refrigerator rather than the door as there can be a lot of temperature fluctuations at the door of the fridge that can degrade the quality of the salmon. It is better to store your raw salmon on the lowest shelf of the fridge to prevent it from dripping into other foods. Fresh salmon lasts for about 1-2 days when stored properly in the fridge at or below 40 degrees Fahrenheit.

Always cook the salmon thoroughly till its internal temperature reaches about 145 degrees Fahrenheit. Never store salmon immediately after cooking because if you store the steaming hot salmon in an air-tight container the moisture will build up inside it that can provide a suitable environment for bacteria to grow therefore you should let your cooked salmon cool thoroughly before storing it.

In case you want to freeze the salmon, it is best practice to wrap it in heavy-duty aluminum foil or thick plastic wrap before putting it in a plastic freezer bag. By doing so you will prevent freezer burns on your salmon.

Raw salmon lasts for about 9-12 months if stored properly in the freezer. On the other hand, if you store cooked salmon in the freezer it retains its best flavor for about 3 months.
