If you prefer to purchase frozen seafood, avoid any packages that are open or torn or have hard ice crystals on them (this could signify that the package was thawed and then refrozen). Also, frozen seafood should not be bendable inside the package.

When cooking, the Centers for Disease Control and Prevention says to separate raw seafood from any ready-to-eat foods. That means you should use a different chopping board and utensils for raw foods, store them separately in your fridge or freezer, and make sure to thoroughly wash your hands with soap and hot water after handling.
