Freezing is often used to kill parasites. According to European Union regulations,[4] freezing fish at −20°C (−4°F) for 24 hours kills parasites. The U.S. Food and Drug Administration (FDA) recommends freezing at −35°C (−31°F) for 15 hours, or at −20°C (−4°F) for 7 days.[5]
While Canada does not federally regulate freezing fish, British Columbia[6] and Alberta[7] voluntarily adhere to guidelines similar to the FDA's.[citation needed] Ontario attempted to legislate freezing as part of raw food handling requirements, though this was soon withdrawn due to protests by the industry that the subtle flavors and texture of raw fish would be destroyed by freezing. Instead, Ontario has decided to consider regulations on how raw fish must be handled prior to serving.[8]
