Public Health Agency of Canada has issued a Public Health Notice with specific advice on avoiding risk from contaminsated oysters, being:

  • Ensure oysters are fully cooked before consuming them. Lightly cooking oysters does not kill norovirus. Oysters need to be cooked to an internal temperature of 90° Celsius (194° Fahrenheit) for a minimum of 90 seconds in order to kill norovirus.
  • Discard any oysters that did not open while cooking.
  • Eat oysters right away after cooking and refrigerate leftovers.
  • Always keep raw and cooked oysters separate to avoid cross-contamination.
  • Do not use the same plate or utensils for raw and cooked shellfish, and wash counters and utensils with soap and warm water after preparation.
  • Wash your hands well with soap before and after handling any food. Be sure to clean and sanitize cutting boards, counters, knives and other utensils after preparing raw foods
