How Long Can Mayo Sit Out?
It is always good to know about its shelf life and how long it will sit out when it comes to any food. Knowing these things helps you prevent your food from spoiling. As for mayo, you can be concerned about mayo itself as well as the sandwiches or salads you prepared using mayo.
Store-bought mayonnaise generally contains vinegar which helps prevent bacterial growth. Also, it is pasteurized, and then the sealed pack can sit out for as long as the expiry date, even a few weeks beyond that. An opened pack of store-bought mayonnaise will last up to eight hours at room temperature. Apart from this, homemade mayo will spoil after two hours of sitting out.
What Happens if Mayo Sits Out Too Long?
You can rest assured about a sealed pack of mayo sitting out for too long. It will experience no harm unless you keep it stored away from heat, such as in the pantry or the top shelf of your kitchen. However, what should concern you is the safety of an opened pack of mayonnaise and the homemade one.
Both of these have a limited time they can stay out for, and after that particular time, you might have to toss it away due to its spoilage. Bacteria grow much quickly in homemade mayo, as it is not pasteurized like the ones bought from stores.
What Should You Do If Mayo Is Left Out Too Long?

In this case, if your mayo is in a pouch and pretty much sealed, it will be safe to consume even after being left out for the night. However, homemade mayo will show you obvious signs of spoilage after this time, and it is better to discard it.
