Below, we will discuss if the mayo goes bad, how you can tell it is bad, and whether you need refrigeration.
Technically, mayo does not need refrigeration, so it does not get stale if you leave it outside overnight by accident. However, if your mayo has expired, but it still tastes, smells, and looks fresh, it is likely safe to eat, provided that you do so within the recommended window, which is two to three months after expiration for store-bought mayo, and two weeks stored in the fridge for homemade mayo. Before opening the mayo, the can be stored in the fridge for approximately three months, or until it expires. Because mayo, besides having long-lasting ingredients, typically has a few extra preservatives, it can easily go several months past its best-by date, or best-before date, when it is not opened.
| Storage | Temperature | Shelf Life |
| Kitchen cabinet | 60-68°F | 8 hours |
| In the refrigerator | 32-34°F | 1-2 weeks |
| Freezer | 0°F | 3-4 months |
Mayonnaise purchased at the store probably will not give you much trouble, so long as it is within the 3-5 month range that canos generally stay safe after they expire. The shelf life of your mayonnaise will vary depending on if it is homemade or store-bought.

Mayonnaises shelf life depends on how it is made, if it is been opened, and what temperature your condiment is stored. For stores-bought bottles like Hellmanns, an opened mayonnaise will stay good for 2-3 months if kept refrigerated. Properly stored, unopened packages of mayonnaise generally will stay in good quality for approximately 3-4 months from the date on the package. An unopened, pre-made can, bottle, or bag of mayonnaise will keep for years, kept at room temperature.
Once opened, a mass-manufactured product will last for just a few hours at room temperature, so be sure to put it into the refrigerator right after using. If you freeze your mayonnaise, it is very likely that the emulsion breaks down as your mayonnaise is thawed, which causes ingredients to become separated. Once the eggs and oils have separated, the texture will be different, and it will not be the same creamy, spreadable condiment.

Mayonnaise is a perishable condiment due to its egg yolk, the primary component in its creamy makeup. If mayonnaise is made at home, the food-poisoning risks are higher due to the unsanitized egg yolk. Traditional homemade mayonnaise contains uncooked egg yolks, which are typically from eggs that were not pasteurized, so foods that contain homemade mayonnaise should be eaten right away or properly refrigerated.
Since most mayonnaise is made from eggs or some kind of egg substitute, it is important to refrigerate it once you make it, or once the can is opened. Even though mayonnaise contains acids which help to destroy bacteria, it still needs to be refrigerated after it is opened. If you are not sure whether or not your mayonnaise is safe, you should throw it out once it starts developing a smell or color.
A foul odor, a darker color than normal, and a strange flavor when you taste it are other signs that your mayonnaise is expired. When your mayonnaise starts smelling really acidic or putrid, you know that it is no longer safe to eat. Mayonnaise can be considered contaminated when you notice signs of mold, or notice changes in the flavor, texture, or smell. Even though mayonnaise can be used for quite some time, you should always be looking for any texture loss.
The shelf life cannot be exact, since the degradation rate depends on the way that you use the mayonnaise. While it is usually considered safe to store mayonnaise for 1 to 2 months after you open it, it remains a fact that your mayonnaise may get worse before then. If you make your own mayonnaise at home, you are best off eating refrigerated products within four days, ideally on the same day. It is best to avoid leaving unopened, professionally packaged mayonnaise at room temperature; keep the unopened one in a refrigerator instead.
To guarantee best flavor, homemade mayonnaise is recommended for storage for only one or two weeks, while store-bought stores are recommended to only last for two months once opened. If you keep your mayonnaise according to USDA guidelines, it will remain fresh and edible 3-4 months after its expiration date. According to Dr. Karen Latimer, a store-bought bottle of mayonnaise can last many months when unopened and stored out of the sun, as industrial-strength mayonnaise contains preservatives that allow for longer shelf-life. Any expired food can harm you if it has the right kind of bacteria growing in it, and mayonnaise is no different.
If you see any spores in your mayonnaise, or any mold around the neck of your can, that is a sure sign the food has gone bad, and you should throw it out immediately. After storing, look for signs that your mayonnaise has started becoming a bacteria breeding site before eating. Any signs of spoilage, like a different flavor, color, or smell, are a sign that your mayonnaise has gone rancid, and you should toss it out immediately.
With most foods, you will need to look at How To Tell If Mayonnaise Is Bad, as we are counting on a fresh-tasting mayonnaise that has not gone rancid or separated. To answer the primary question, it is certainly possible for store-bought mayo to turn rancid or spoil, but it takes a good while before it gets there. What is most likely to happen is you throw it out because it is no longer of high enough quality, rather than because eating it makes you ill. Just likeketchup, hot sauce, and soy sauce, we use mayonnaise in our foods very frequently, and therefore, we need to make sure the mayonnaise is fresh and good, as eating a poor quality mayonnaise will get you sick from food poisoning.
