Can thawed strawberries go bad if left out all night?

Yes, thawed strawberries can go bad if left out all night.

When you thaw frozen strawberries, you break down their cell walls, which makes them more susceptible to spoilage. If the strawberries are left out at room temperature, bacteria will start to grow and multiply. This can cause the strawberries to become mushy, develop an off smell, and lose their flavor.

It is important to keep strawberries refrigerated at all times. If you plan to use thawed strawberries, be sure to do so within a day or two.
