    I was defrosting salmon in the sink. It was wrapped in wax paper but not tightly. Water got inside. Is it still safe to eat if baked at 375 degrees?

    Yes, the heat will kill any bacteria in the sink. Next time, disinfect your sink before use or put the fish into a large bowl to defrost it.

      Tips

      • Label and date your packed salmon before storing it the freezer, so you can ensure it has not been in the freezer for longer than 8 weeks before you eat it.
      • If you are defrosting a whole salmon, check the inner cavity for ice chunks. Run cold water on the cavity to finish defrosting salmon.

      Warnings

      • Make sure it has not been improperly frozen. Home freezers have fluctuating air flow and temperatures and are not meant for long term storage. Eat your salmon within 2 to 3 months after buying and freezing it. If it has been exposed to air, either in the package or in the freezer, it has not been properly frozen and should not be defrosted and eaten.
      • Never refreeze salmon after it has thawed.
      • Do not thaw fish with warm water. This promotes the growth of bacteria.

      About This Article

      Article Summary X

      The safest way to defrost salmon is in the fridge. About 12 hours before you plan to cook your salmon, take it out of the freezer and remove any excess packaging, so it’s wrapped in just one layer of plastic or foil. Set the fish in a shallow bowl and place it on a flat surface in your fridge, preferably away from other foods that could soak up the smell of the salmon as it thaws. After 12 hours, take the salmon out of the fridge and cook it immediately. If you’re in a hurry, skip the fridge and place the frozen salmon in an airtight plastic bag. Then, put the bag in a large bowl or sink basin filled with cold water. This technique usually only takes about half an hour, but if it takes longer, change the water every 30 minutes. Once the salmon is thawed, remove it from the water and cook it right away. For an extra quick defrost, unwrap the salmon and put it on a microwave-safe plate lined with paper towels. Place another layer of paper towels on top of the fish. Set the microwave to “defrost” and microwave the salmon for 4 to 5 minutes for every 1 lb (.45 kg) of fish. Halfway through the defrost time, take the fish out of the microwave and turn it over. When you’re done, let the fish sit on the counter for another 5 minutes to finish defrosting before you cook it. Keep reading to learn how to defrost salmon in the microwave!
