Have you ever opened a bag of chips, expecting only crispy, flavorful bites, but instead, you found a mysterious blue disc hidden among them? If so, you’re not alone. Many people have stumbled upon this puzzling object, often embossed with text such as “Ferrous 25mm BST, Cert No. 213026B.” But what does it mean? And more importantly, how did it end up in your snack?
What Is the Blue Disc Found in a Packet of Chips?

At first glance, you might think it’s a promotional token, a production defect, or even an unexpected prize. However, this small blue disc is actually a metal detector test chip used in food processing plants.
This test chip is designed to ensure that food safety equipment—specifically, metal detectors—are working correctly. These chips are strategically placed on the production line to verify whether the detectors can identify and remove potential foreign objects. The blue color helps it stand out from the food, making it easier to spot if something goes wrong.
Why Are Metal Detector Test Chips Used in Food Manufacturing?
Food safety is a top priority for manufacturers. The presence of any foreign object, whether metal, plastic, or glass, poses a significant risk to consumers. To prevent contamination, most factories use metal detectors to scan food items before they are packaged and shipped.
Here’s how the process works:
- Test chips—like the one you found—are deliberately inserted into the production line at set intervals.
- Metal detectors scan the products, ensuring they catch the test chips.
- If the machine detects the chip, it triggers an alert and removes the contaminated item.
- If the chip is NOT detected, it signals a potential failure in the system, and production is halted until the issue is resolved.
Why Did the Test Chip End Up in My Chips?
Now, here’s where things get concerning. The very reason test chips exist is to prevent foreign objects from getting through. So if you found one in your bag of chips, it means something seriously went wrong in the quality control process.
There are a few possible explanations:
- The chip was misplaced and never retrieved – This suggests a human error where someone forgot to remove the test chip after conducting quality control.
- The metal detector failed – This is the most alarming possibility. If the detector failed to catch the test chip, it may have also missed other harmful objects, such as metal fragments or contaminants.
- Production oversight – Sometimes, manufacturing processes get rushed, and crucial safety checks are overlooked.
Regardless of the reason, this is a major red flag that warrants immediate action.
What Should You Do If You Find a Metal Detector Test Chip in Your Food?
If you ever find a test chip inside a food product, take the following steps:
- Do NOT consume any more of the product – There could be other contaminants present that went undetected.
- Keep the packaging and the chip – This will be crucial when reporting the issue.
- Contact the manufacturer immediately – Most brands have customer service lines or emails where you can report quality concerns.
- Request an explanation and possible recall information – If a test chip made it into your food, there’s a chance others might have had the same experience.
- Consider reporting the issue to a food safety authority – Agencies like the FDA (in the U.S.) or the FSA (in the UK) monitor food safety standards and may investigate further.
Will the Manufacturer Face Consequences?
Yes! Food safety protocols require companies to document every test chip used in their quality control process. When a test chip goes missing, production should stop immediately until it is found.
If you report the incident, the company will likely conduct an internal investigation to determine how this breach occurred. In some cases, it may even lead to:

- Product recalls – If multiple reports emerge, the company may be forced to recall entire batches of the affected product.
- Fines and penalties – Regulatory agencies may impose fines if they determine that safety protocols were neglected.
- Operational reviews – Manufacturers might overhaul their processes to prevent similar failures in the future.
Could There Be Other Foreign Objects in My Chips?
The unfortunate reality is that if a test chip made it through, other foreign objects could have as well. While food safety measures exist to minimize risks, errors do happen. There have been cases of consumers finding:
- Plastic or rubber fragments from conveyor belts
- Metal shavings from broken machinery
- Glass pieces from shattered equipment
- Insects or other biological contaminants
This is why quality control is so critical. The presence of a metal detector test chip in your chips raises serious questions about the reliability of the manufacturer’s safety measures.
Final Thoughts: Should You Be Concerned?
Absolutely. While finding a blue test chip in your chips might seem like a bizarre fluke, it’s actually a major food safety failure. These chips are meant to stay on the production line, not end up in your snack bag.
If this happens to you, take action. Report it, demand accountability, and spread awareness. Food safety should never be compromised, and manufacturers must be held to the highest standards to ensure that what we eat is truly safe.
Jamie Lee Curtis breaks down in tears over shocking revelation!
Jamie Lee Curtis said some very sad things about her close friend and Curb Your Enthusiasm star Richard Lewis, who died on Tuesday of a heart attack at the age of 76.
The 65-year-old actress who played the witch in Halloween also starred with the comedian in the sitcom Anything But Love, which ran for four seasons from 1989 to 1992.
She posted on her main Instagram page on Wednesday after hearing the sad news that the actor had died. Bette Midler was the first to share the news.

Curtis posted a bunch of old pictures of herself with Lewis and wrote a long caption in which she thanked the late star for being “the reason I am sober.”
This month, Jamie celebrated 25 years of being sober after struggling with an opioid addiction.
“I just learned that my friend Richard Lewis has died.” I remember exactly where I was on Sunset Boulevard when I saw a billboard of him for a stand-up special. It was during the casting process for the ABC pilot Anything But Love, and I asked the casting staff to bring him in to try out for the part of Marty Gold, my best friend and maybe boyfriend.
“I thought he looked good.” Someone made me laugh, which is something a strong woman can’t really do for herself. I laughed out loud when he pronounced the word “Bundt cake” wrong, but he got the part.
“He blew everyone else away,” Jamie said. They didn’t pick up the pilot for the love triangle show, but they got back to me and said, “The chemistry with Richard was so great. Could we revamp the original pilot?” That’s how we ended up making the show for two years.

“He was also a stand-up comedian, but he hated performing in front of real people. I, on the other hand, loved it.”
He would hide his lines on props, door frames, and even my face in a close-up. He also always had his lines written on a clipboard with him. He played roles very well, it turned out. It’s deep and so damn funny.
She said, “We grieved together over the death of our friend and co-star Richard Frank and over the death of our friend and producer John Ritter.”
“In his last text message to me, Richard hoped that I could get ABC/Disney to release another boxed set of episodes of the show,” she wrote to her fans.

Then Jamie said, “He’s also the reason I’m sober.” He helped me. I will always be grateful to him for that act of kindness.
They talked about his wife, Joyce Lapinsky, and she said, “He found love with Joyce, and that, of course, along with being sober, was what mattered most to him.” It makes me cry to write this.
This is a strange way to thank a nice and funny man. Richard, may you rest in laughter. “My Marty, I love you, Hannah!” she said in the end.
Jamie also wrote a second post about how sad she was about the death of her longtime friend and former co-star.
She added another old picture of herself with Lewis and some lyrics from the Anything But Love theme song.
“In the third and final season of the TV show ANYTHING BUT LOVE, which aired on ABC for a few years, the great singer-songwriter JD Souther wrote this beautiful theme song,” Curtis wrote.

“Try to find it on YouTube and listen to it. If not, I’ve written it down here for you.” Today I’m giving them to my friend Richard Lewis.
She shared lyrics that said, “If we had never met/And the world got on without us/Just as if we were never that at all,”We would still be looking for the next big thing and trying not to fall…
“Anything but love will do and hearts that beat like thunder.”For everyone but you, anything but love would be enough.
Larry David, who also stars on Curb Your Enthusiasm, and other famous people and social media users paid tribute to the late Richard Lewis.
“He’s been like a brother to me for most of my life,” he told HBO. “Richard and I were born three days apart in the same hospital.”
“He was the funniest and nicest person at the same time, which doesn’t happen very often.” The comedian told Variety, “But today he made me cry, and I’ll never forgive him for that.”
Cheryl Hines, who worked with Lewis on the hit show, wrote, “When I was young, I had the biggest crush on Richard Lewis.”

“There was no one funnier or more handsome on stage than him.” Then I got to work with him on Curb Your Enthusiasm, which was a dream come true.
“Over the years, I learned more about Richard and the gifts he gave.” I fell in love with him because he was funny, but he was also one of the nicest people I know.
“Especially in the last few years,” Cheryl said, “he would take the time to tell the people he loved how much they meant to him.” He told me how important I was to him and how much he loved me in between takes on Curb.
“To be loved by Richard Lewis.” A real gift. Richard, I love you. We will miss you. I love you, Joyce, and everyone in Richard’s family. Lawrence, Richard loved you…You already know that, though.
