If vacuum-packaged fish is not properly stored and thawed, it has the potential to create a deadly toxin that can harm consumers. Clostridium botulinum type E can be found in fish and can grow in a refrigerator.
The bacteria can survive for up to two weeks in the freezer and can cause serious illness in people who have not been exposed to it before. It can also cause miscarriages, stillbirths, and even death in pregnant women.
In the United States, the Centers for Disease Control and Prevention (CDC) estimates that 1.5 million people die each year from food-borne botulism, which is caused by the bacterium.

Don’t Squish the Fish For this reason, I like to flash freeze fish before I vacuum seal it. Wrap each fillet in plastic wrap, and freeze for about 3-to-4 hours until it starts to harden up. Remove the plastic wrap, and then vacuum-seal it. Doing this will make sure the vacuum seal doesn’t remove any water from the fish.
When you’re ready to eat your fish, remove it from the freezer and place it in a bowl of ice water. Allow it to sit for a few minutes, then drain off the excess water and pat it dry with a paper towel. You may need to do this several times, depending on the size of your fillets. Once it’s dry, slice it into bite-sized pieces and serve with your favorite dipping sauce.
