Sushi and Sashimi

Foodborne illnesses involving sushi, including sushi containing sashimi (or raw fish) tend to be less frequent than those from many other potentially hazardous foods. However, eating raw fish and seafood can increase the risk of human disease from parasites and other microbes that are typically destroyed by cooking.
Risks from parasites (freezing does not destroy viruses or bacteria) can be prevented through freezing fish to a temperature of -35 degrees C or below for 15 hours and then held at -20 degrees C for 24 hours.
