  • Pay special attention if pooled eggs (liquid eggs made by combining a number of cracked, raw eggs in a container) are used:

    • Store pooled liquid eggs in the refrigerator and only take out the amount as needed.
    • Use all pooled liquid egg on the day of pooling and avoid topping up by new eggs.

    • Pooled liquid eggs should not be used to prepare raw or uncooked egg-containing dishes.
  • Indicate the presence of raw or undercooked foods/ingredients in ready-to-eat items to help consumers make informed choices by providing a consumer advisory on labels or placards stating, for instance, “Consuming raw or undercooked foods may cause illness, especially for pregnant women, young children, the elderly and people with weakened immunity.”
