Like hand sanitizer for your insides.

The headmaster of a culinary school told me that if you were to eat wasabi with every meal you would never succumb to food poisoning. That's because it acts as an internal antibacterial agent. So when my husband came back from the restroom at Roca in London, England and told me a wait staff didn't wash their hands according to North American health standards -- soap, water and Happy Birthday -- I was indifferent. Yes, the Hygiene Hunter said, "Let's order pork sashimi." That's because I am a good pupil. I very much enjoyed the food at this Japanese restaurant despite my significant other's keen eye. Hit & Miss.
