You can, however, eat crab, shrimp, squid and lobster without cooking them...

[drjasonharrison]

If these animals are eaten raw after "it has been frozen at -18’C for a minimum period of 14 days". AKA "sashimi quality"

Otherwise you are risking serious illness. From either pathogens of marine origin or later handling.

Crab: parasitic flukes (liver flukes and lung flukes), roundworms (e.g. Angiostrongylus cantonensis) and tapeworms (e.g. Diphyllobothrium spp.). Viruses: norovirus and Vibrio parahaemolyticus.

Lobsters: Vibrio parahaemolyticus, Vibrio vulnificus, Vibrio cholera.

Shrimp and Squid: many of the same.

A Japanese YouTuber which shows how to filet fish usually eats a slice of everything raw and gets sick regularly. But he can’t resist to try it.

He's lucky to be able to do it more than once. A friend's cousin got acute reaction from pathogens in raw fish which got him to ICU and now the doctor said he should avoid eating even cooked fish because he could do an allergic reaction.
