When is cauliflower unsafe to eat?

Cauliflower is unsafe to eat when it shows signs of spoilage, such as discoloration, a strong, off-putting odor, or a slimy texture. Additionally, if it has developed soft spots or mold, it should be discarded. Proper storage is essential; if left unrefrigerated for an extended period or stored improperly, it can also become unsafe. Always wash it thoroughly before consumption to remove any pesticides or contaminants.
