I was startled when my son found a small blue disk inside a bag of sour cream chips and refused to let him eat them until I knew what it was. After sharing a photo online, I learned it wasn’t dangerous at all—it was part of a food safety process.
The disk is a test device used by manufacturers to check metal detectors during production. It’s harmless and meant to ensure equipment is working properly to keep contaminants out of food, offering an unexpected but reassuring look at the safety measures behind packaged snacks.
