If you’re not sure if a bell pepper is bad, feel it! There’s a small indent near the stem end. This means it’s spoiled. Otherwise, it’s OK to eat it but throw it away. You should throw it out if it feels slimy, shriveled, or rotten. This is the first sign that your bell pepper is terrible. To know if your bell pepper is bad, look for signs of deterioration, such as the skin becoming soft or the color turning brown or black.
