I was surprised when my son opened a bag of sour cream chips and found a small blue disk inside. At first, I had no idea what it was, so I didn’t let him eat the chips. Concerned and curious, I took a photo and shared it online to see if anyone could explain what this unusual item was. The responses I received revealed an interesting part of food safety that many people might not know about.
After researching and reading online discussions, I learned that this blue disk is a test device used in food production. It is specifically designed to pass through metal detectors to ensure that the machines are correctly detecting any metal particles in food products. This is a routine part of quality control, aimed at preventing dangerous objects from reaching consumers.
