Do Blueberries Need to Be Refrigerated?

Blueberries are a healthy, delicious treat. Moreover, they are easy to find and affordable. But, do blueberries need to be refrigerated? If you’re wondering how to store blueberries, you might be concerned about the long-term shelf life of the fruit.

It is recommended that you refrigerate blueberries, especially if you don’t plan to eat them the same day of purchase. This is because blueberries degrade very quickly and only last for about a day if stored at room temperature.

In short, if you intend to eat them in the next day or so, there’s no need to refrigerate them and you can leave them on the counter. On the other hand, you will need to refrigerate them if you plan to store them for more than a day.

When refrigerating them, avoid putting them in the crisper drawer because air doesn’t circulate there too well.


Can Blueberries Be Stored at Room Temperature?

You can keep blueberries at room temperature for short-term storage, i.e. a day or two. If you plan to eat them the same day of purchase, simply store them in a shallow container on your kitchen counter at room temperature for the best flavor.

Since they degrade very quickly, they should never be stored at room temperature for more than a day.

Blueberries are delicious, but not very hardy. They tend to wilt quickly if not stored properly. Blueberries need to stay cool because they’re highly perishable.

How Long Can You Leave Blueberries Unrefrigerated?

Blueberries have a very short shelf life. They start to decay as soon as you bring them home from the grocery store. Even if they are fresh, they can last only about a day when you leave them unrefrigerated.

Can I Eat Blueberries That Aren’t Refrigerated?

If the blueberries haven’t been left unrefrigerated for more than a day, you can eat them. Blueberries can retain their freshness and don’t go bad if kept at room temperature for a day.

In ideal conditions, they can even last two days. But generally, it’s a good idea to eat them on the same day of purchase if they haven’t been refrigerated. Just to be sure, you should check for any signs of spoilage before eating them.

Use your senses, i.e. smell, touch, and look for signs of mold growth. If there is mold growth or the blueberries smell foul, throw them away.


How Should Berries Be Stored?

Storing berries in the refrigerator is considered the best method as it allows you to keep them fresh for longer. Blueberries are delicate and spoil easily but if you follow the proper storage guidelines, you can keep them fresh for a long time.
