Deep freezing probably does kill most parasites.

In general, killing parasites requires freezing and storing fish at a surrounding temperature of minus 4 degrees Fahrenheit or colder for seven days; or freezing at a surrounding temperature of minus 31 degrees or colder until the fish is solid and storing at the same temperature for 15 hours; or freezing at a surrounding temperature of minus 31 degrees until the fish is solid and storing at minus 4 degrees or below for 24 hours.
