Do spots on a tea bag mean it is expired?

The spots on tea bags that you are referring to are most likely mold. Mold can grow on tea bags when they are stored in humid conditions. Mold is not harmful to humans, but it can affect the taste of the tea. If you are concerned about the mold on your tea bags, you can discard them and purchase a new package of tea.

Here are some tips for preventing mold on tea bags:

- Store your tea bags in a cool, dry place.

- Keep tea bags away from sources of moisture, such as the sink or the dishwasher.

- Do not store tea bags in direct sunlight.

- Once a package of tea bags has been opened, it is best to use them within a few months.
