How can you tell if coleslaw has gone bad?


Novice Foodie
How do you guys tell if coleslaw gone bad? I usually start sniffing it; anything sour or funky, and I'm wary. Looking for color changes or sliminess helps too. I've been told tasting should be a last resort—if it tastes off, it's straight to the bin. Is there another trick I'm missing? :unsure::unsure:
You can check if the carrots are already mushy and the cabbage has turned dark and looks slimy. Those are clear indicators that your coleslaw has gone bad and is not safe to eat.
