Raw protein is said to be better for digestion than cooked protein in Japan so some Japanese believe if making convalescent eat sashimi ,who will get over very soon.
However when you see cutting up whole fish show at seafood whole sale market like Tsukiji or a fish store in Japan, you will understand that work isn't done in a perfect clean sanitary environment and hands of those who cut up fish and knives are not perfectly sterilized like surgical instrument. If we think this way, we feel very much reluctant to let patients eat raw food like sashimi rather than cooked fish but Japanese hospital provide sashimi as one of side dish for a dinner meal to patients except for ones who has food restrictions by a doctor. I wonder why I've never heard food poisoning accident from hospital providing sashimi as one of invalid diet to patients.
One of the reason of no food poisoning accident from hospital is because Japanese food culture is very good at using type of spices with germicidal action like wasabi to eat any raw foods. In the period of time of no refrigerator, ideas of eating raw fish safely reached eating with strong spices or unique seasoning such as Karashi, wasabi, su(vinegar), shoyu by virtue of Japanese cooks' long experience.
The pungency of wasabi derives from the pungent component Allyl isothiocyanate, which has strong antibacterial and germicidal action.
When letting Allyl isothiocyanate stay on nutrient agar which has 271 colon bacillus for 30 minutes, the number of colon bacillus became 77. In case of 60 minute stay, the number of colon bacillus became 5. In case of 24 hours stay, the number of colon bacillus became 0. In like manner, In case of 38 Vibrio parahaemolyticus staying on nutrient ager, putting wasabi on it for 30 minutes , the number of Vibrio parahaemolyticus became 0.
