Who do you know when sweet peppers are bad?

Sweet peppers are bad when they show signs of spoilage, such as soft spots, wrinkles, or an overall mushy texture. Additionally, if they have an off or sour smell, or if their skin has dark spots or mold, it's best to discard them. Fresh sweet peppers should be firm, vibrant in color, and free from blemishes. Always trust your instincts—if it looks or smells questionable, it's safer not to consume them.
