So, how do you know when your macaroni salad has gone bad? Well, if it's been longer than 5 days, it's probably time to bid adieu. Other signs include a slimy texture, an off smell, or mold growth - yuck! If you notice any of these, it's best to err on the side of caution and toss it.
It's also important to consider the ingredients in your macaroni salad. If you've added mayo or sour cream, it might not last as long as a salad made with Italian dressing. Think of it like a shelf life - some ingredients are more perishable than others.
