Does Mayo Need to Be Refrigerated?

Mayo should be refrigerated to maintain its freshness and quality.

This is because pantry staple mayonnaise contains eggs and other perishable ingredients.

Unopened mayonnaise can be stored in a cool, dry place until the expiration date on the package.

Once unsealed, the opened mayo should be refrigerated at a temperature below 40°F (4°C) and used within 1-2 months.
