Does cornstarch go bad?

No, cornstarch doesn't truly "go bad" and has an indefinite shelf life if stored properly in a cool, dry place, but its thickening power might slightly decrease over years, though it remains safe; it only spoils if exposed to moisture, causing mold, or if bugs get in, in which case you'll see mold, clumps, or a bad smell, and should discard it. For best quality, use within the "best by" date, but it's fine long after if sealed and dry.
