How long does mayonnaise, commercial last?
Mayonnaise, commercial keeps for about 3 to 6 months in the pantry. Counted from the date of purchase.
| Where | How long |
|---|---|
| Pantry | 3 to 6 months |
| Refrigerator, after opening | 2 months |
Refrigeration ensures that commercial sauces and condiments stay fresh for a longer period of time. Shelf-stable commercial mayonnaise is safe when stored at room temperature after opening. Quality, not safety, is the reason the labels on these products suggest that they be refrigerated after opening.
Storage times are the USDA FoodKeeper guidance for quality and safety, not a guarantee; a printed use-by date on the package comes first. Source: USDA FSIS FoodKeeper (CC0), fetched 2026-10-27, category Condiments, Sauces & Canned Goods.
