How Long Does Mayo Last in the Fridge?

Mayonnaise is a popular condiment that can enhance the flavor of various dishes, but knowing how long it remains safe to use is crucial for maintaining both taste and food safety.

Shelf Life of Mayonnaise

Once opened, mayonnaise should be consumed within 2 to 3 months for optimal quality. The key to extending its shelf life is to keep it consistently refrigerated at or below 40°F (4°C) and ensure the lid is tightly sealed after each use.

Factors Affecting Freshness

Several factors can affect how long mayonnaise lasts. Exposure to air and fluctuating temperatures can accelerate spoilage. Additionally, contamination from utensils or hands can introduce bacteria, reducing the product’s shelf life. Always use clean utensils when handling mayonnaise to prevent contamination.

Signs of Spoilage

It’s essential to check for signs of spoilage before using mayonnaise. If the mayo has an off smell, unusual texture, or visible mold, it should be discarded. Even if these signs are not present, if the mayo has been stored for longer than the recommended time, it’s better to err on the side of caution and not use it.

Storage Tips

To maximize the shelf life of mayonnaise, keep it in its original container and store it in the coldest part of the fridge. Avoid leaving it out at room temperature for extended periods, as this can lead to bacterial growth and spoilage.

In summary, while mayonnaise can last for several months in the refrigerator, proper storage and regular checks for spoilage are essential to ensure its safety and quality. By following these guidelines, you can enjoy mayonnaise with confidence while keeping your food safe.
