Only storage locations with source-backed entries are shown; a missing freezer or pantry card means FoodLasts does not have a supported value.
Unopened and after-opening tabs are split because the source data has separate entries.

Based on USDA/FSIS guidance:

Keep eggs and refrigerated dairy at 40°F or below; sell-by dates are quality guides, not safety deadlines when storage has been cold.

Discard yogurt that is fizzing, bulging its lid, or smells yeasty, as these indicate unwanted fermentation.

Can you freeze Yogurt?

Yes.Yogurtkeeps 1–2 monthsin the freezer when stored in airtight packaging.

Yogurt is safe to freeze, but its smooth texture breaks down once thawed, turning watery and grainy as the whey separates from the curd. Freeze it in a rigid tub with a little headroom, or spoon it into ice-cube trays, for 1–2 months. Thaw in the fridge and whisk well; use it in smoothies, baking, or cooking rather than eating by the spoon.
