Shelf-life windows come from the USDA FoodKeeper, published by the USDA Food Safety and Inspection Service (public domain); we vendor the FSIS FoodKeeper dataset and refresh it in place. These are quality estimates, not food-safety determinations or guarantees: actual condition depends on storage and handling, and harmful bacteria may not have obvious signs. Follow package and official guidance; when in doubt, throw it out. See our food safety notice and terms.
