ELI5:If deep freezing only puts bacteria to sleep rather than killing them, then why does deep freezing sushi/sashimi fish makes them safe to consume raw?

I've been told that deep freezing food doesn't kill all the bacteria and only puts them to sleep. However, when I look up about sushi/sashimi, they often say that freezing the fish is one of the things they do to kill bacteria.  What's the true story here?

I think you're confusing bacteria with parasites. Freezing kills harmful parasites like tapeworms and roundworms. 

The bacteria you're concerned about has nothing to do with the fish itself and everything to do with who handles it. If there is any harmful bacteria on your sushi, I'd blame your chef for not washing their hands.
