Oh, and if you’re wondering what makes the cereals pop, we’ll share it with you in this article too!
Do Rice Krispies Go Bad?
Yes, it does go bad.
The good news is it won’t expire since it contains little to no moisture. Not only that, all of its ingredients are shelf-stable products, so it definitely lasts for a long time.
However, it goes bad in the sense that it will become stale, especially if it’s already opened. This may cause changes in texture and loss of flavor.
Do Rice Krispies Treats Go Bad?
Yes, Rice Krispies Treats can go bad too, but in a different way.
While plain Rice Krispies will become stale, Rice Krispies treats will become rancid. This is because such treats use butter, oil, or marshmallows which are all prone to rancidity.
The rancidification process won’t just change the treats’ texture but will also give the treats an unpleasant taste.
How Long Do Rice Krispies Last?
The packaging of Rice Krispies comes with a printed date. It’s important to note that this is a best-by date (indicates quality) and not an expiration date (indicates safety).
To clear things up, you can still safely eat the Rice Krispies (as long as it doesn’t show signs of spoilage) past the printed date. However, it will start to lose freshness by then.
Ideally, an unopened box of Rice Krispies can last for a year past the printed date. On the other hand, an opened box can last for up to 6 months after being opened.
Where to Find Expiration Date and How to Read Them?
The best-by date is placed in any of these two places:
- At the top or bottom of the box
- Backside or front side of the individual bags
Kellogg’s, the company behind this cereal, formats their printed date in this way—MMDDYY. The first two digits represent the month, followed by 2 digits representing the days, and the last 2 digits as the year.

Since these contain unstable ingredients, they have a shorter shelf life—only around 1 week or until they show signs of rancidity.
How to Tell if Rice Krispies Have Gone Bad?
On their own, the cereals won’t spoil but they will go stale. However, various external factors may cause it to spoil. If this happens, you should avoid consuming it to prevent food poisoning.
That’s why it’s important that you inspect it for any of the following signs of spoilage:
Oily Texture and Weird Smell
The presence of bacteria, like Salmonella, will cause the cereals to have an oily texture. It will also cause a weird smell similar to that of grass and paint.
If your cereals have been exposed to moisture, there’s a high chance that mold will grow in them. Once your cereals start to show dark or green spots, it’s best that you throw them right away.
Presence of Bugs and Insects
An opened box of cereals can easily get infested by pantry bugs and insects, especially when it wasn’t sealed properly.
While these insects might be harmless, it’s best to stay on the safe side and throw away contaminated cereals.
How to Store Rice Krispies to Make Them Last Longer
The best way to prevent cereals and treats from spoiling is to store them the right way. Here are some tips on how to do it:
Store an unopened box in a cool, dark, and dry place.
To prevent the cereals from oxidizing, keep them away from sources of heat and light to prevent the marshmallow and butter in the treats from melting.
Once opened, transfer the cereals to an airtight container.
Make sure that the lid is tightly sealed to prevent them from losing their crispy texture.
Extend its shelf life by freezing or refrigerating it.
If unopened, you can place it inside the refrigerator in its original packaging. But if it’s already unopened or you plan on freezing it, make sure to place it in a freezer-safe bag to protect it from freezer burn or the dry air in the refrigerator.
