How do you tell if blueberries are spoiled?

1. Mold: Look for any signs of mold growth on the blueberries. Moldy blueberries should be discarded immediately.

2. Color Changes: Fresh blueberries should have a deep, vibrant blue color. If you notice any discoloration, such as browning, this could indicate spoilage.

3. Softness: Ripe blueberries should be soft, but not mushy. If the blueberries are very soft or have a wrinkled appearance, they are likely overripe and should be discarded.

4. Leaking Juice: If the blueberries have started to leak juice, this is a sign that they are overripe and should be discarded.

5. Smell: Fresh blueberries should have a slightly sweet and fruity smell. If you notice any unusual or off-putting odors, such as a sour or fermented smell, discard the blueberries.

6. Taste: If you bite into a blueberry and it has an off or sour taste, spit it out and discard the blueberries. Consuming spoiled blueberries can lead to foodborne illnesses.

It's important to note that it is always better to err on the side of caution when it comes to consuming fresh produce. If you are unsure whether blueberries are still safe to eat, it is best to discard them.
