Can Salmonella bacteria be killed by freezing?

Salmonella and other bacteria are not killed by freezing. Some of the cells present will indeed die, but quantities sufficient to cause infection will remain. This implies that after defrosting bacteria can continue growing. The growth of bacteria, however, will stop in the freezer; a possible risk will therefore not increase during freezing.
