Raw seafood such as fish, shellfish and shrimp is the main ingredient of a Japanese dish called sashimi. In recent years, fish consumption in natura has been increasing in Brazil, with raw fish (sashimi) being more and more consumed in specialized restaurants. Japanese cuisine may be considered one of the main contributing factors in the increase of fish consumption, introducing and innovating the preparation of raw seafood in regions where it could rarely be found before. Several Brazilian cities have now become gastronomic centers with a lot of restaurants providing Japanese food ( de Moura Filho et al., 2007).
