However, nearly all fish contain harmful parasites and microorganisms and must be frozen at some point before it may be safely consumed raw.

For example, salmon frequently contains roundworm larvae that cause illness in humans if consumed. Most salmon catchers flash-freeze the fish on the boat immediately after catching.
