How do you know when dried chile peppers are bad?

Dried Chile peppers can go bad if they lose their vibrant color, become brittle, or develop an off smell, such as a musty or rancid odor. If they show signs of mold or insect damage, they should be discarded. Additionally, if the peppers have lost their flavor or potency when rehydrated, it's a sign they may no longer be good. Always check for these indicators before use.
