Hellmann's Mayo has a shelf life of approximately 2 months after it is opened. However, this can vary depending on storage conditions. To ensure the mayo stays fresh for longer, it should be refrigerated and kept at a consistent temperature between 35-40°F (2-4°C). It's important to always check the expiration date on the jar before consuming. If the mayo shows visible signs of spoilage, such as an unusual odor or texture, or if it has been left unrefrigerated for an extended period, it is recommended to dispose of it. Proper storage and timely consumption will help maintain the quality and taste of Hellmann's Mayo.
