Which date should I enter?
Use the date the food entered the specific condition you selected. Opening, cooking and prompt cooling can change which reference applies. A date is not a substitute for handling history or a package use-by instruction.
Important distinction
The official source does not recommend freezing live shellfish, while shucked products have freezer quality guidance.
Safety: These are general reference intervals. Refrigerator figures assume promptly handled food kept at 40°F / 4°C or below; freezer periods concern best quality. This comparison cannot establish that food is safe to eat.
