When it comes to bread being bad, there are some pretty obvious signs. Visible signs of mold or white, black, blue, or green spots on the bread are a sure sign it has spoiled and you should discard it. If your store-bought bread smells sour (like vinegar), yeasty, or even like alcohol, get rid of it too
