How To Tell If Cauliflower Has Gone Bad
All foods will eventually go bad after exposure to air through oxidative decay or degradation, though you can slow the process with proper care and storage methods. Cauliflower can last about one to three weeks with good storage practices, and there are several clues that indicate the food has spoiled.
You might notice light-brown spots on cauliflower caused by oxidation, but the vegetable is still safe to eat at this point; however, if those spots turn dark brown or black, it's time to get rid of the cauliflower. Other indicators include an off-smell, slimy texture, or soft spots on the vegetable that let you know it needs to be thrown out.
If the cauliflower has mold growing, it's always best to be cautious and discard moldy cauliflower rather than take any chances, especially if the mold is black. When buying the vegetable at the store, avoid any loose or discolored florets, and always leave it in its original packaging until you're ready to use it to ensure it lasts longer.
