The use-by date of a stored bowl of potato salad is today. Can the salad be served?

If the use-by date of the potato salad is today, it is generally considered safe to serve it, provided it has been stored properly and shows no signs of spoilage, such as an off smell, discoloration, or unusual texture. However, it's important to use your judgment and ensure it has been kept at the right temperature throughout its storage. If in doubt, it's safer to discard it to avoid any risk of foodborne illness.
