This is a true case of a Japanese man from Gifu prefecture who complains incessantly about a persistent headache. Mr. Shota Fujiwara loves his sashimi and sushi very much tothe extent of trying to get them as 'alive and fresh' as can be for his insatiable appetite. He develops a severe headache for the past 3 years and has put cut off as migraine and stress from work.. It was only when he started losing his psychomotor skills that he seeks medical help. A brain scan and x-ray reveals little however.
But upon closer inspection by a specialist on his scalp, the doctor noticed small movements beneath his skin. It was then that the doctor did a local anesthetic to his scalp and discovered the cause when tiny worms crawled out.
A major surgery was thus immediately called for and the extent of the infestation was horrific. See the pictures below to the scene that one thought only a movie could produce.: sushiworms.jpg / sushiworms2.jpg
Remember, tapeworms and roundworms and their eggs which abound in all fishes fresh or salt fishes can only be killed by thorough cooking and/or freezing the fish to between 4 deg C - 0 deg C. The eggs of these parasites can only be killed if it is cooked or frozen to the said temperatures for a week or more. Think twice about that raw dish next time...or you might get a headache.
