Just like any other fruit, a blueberry can easily go bad when not stored properly. The sugar and water content in blueberries is what causes them to go bad so easily.

Here are some of the signs that your blueberry has gone bad:

Mold or fungus

If you notice any kind of mold or fungus growing on your fruit, then this also means that it has caused damage to the inside as well and thus is not safe to eat at all. If you notice any of these signs, just throw them away as they can cause serious health issues.

The white coating looks like mold, but it’s actually a natural chemical reaction due to high acidity and polyphenol oxidase enzymes ( tyrosinase ).

A change in color

If your blueberry starts having a uniform dark blue color instead of its original dark purple hue, you should immediately get rid of it because it also means that your fruit is not fresh anymore.

A sour smell

Sometimes when you open a pack of blueberries, they may have a slight smell which is actually good for the fruit, but if you start noticing strong odors, then this is also a sign that your blueberry has gone bad and is not safe to eat anymore.
