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.
Reba McEntire’s Heart-Wrenching Tribute: Remembering the Day Tragedy Struck 32 Years Ago
Today, Reba McEntire is 68 years old, and she truly deserves all the praise she gets. It feels like she has been part of my life forever, and I still listen to her music several times a week.
However, Reba’s life hasn’t always been easy. This year marks the 32nd anniversary of a tragic plane crash that took the lives of several of her friends.

After breaking into country music in the late 1970s and early 1980s, Reba McEntire was named “best singer” for four years in a row by the Country Music Association. She also has a star on the Hollywood Walk of Fame.
But despite her amazing career and success, Reba has faced many personal challenges. In 2022, her mother, Jacqueline, lost her battle with cancer at the age of 93.
“She had a wonderful, full, healthy life and was absolutely ready to go. The cancer might think it won the battle, but we’re giving God all the credit for choosing the time for her to go home,” the country star wrote on social media.
Jacqueline McEntire always dreamed of being a professional country singer, and she was the one who taught Reba to sing, fulfilling her ambitions through her daughter.
“She left knowing how much she is loved, and we all know how much she loved us. We’re all going to miss her, but we have so many wonderful memories,” Reba said.
Reba truly understands what it means to face sorrow and loss.

Thirty-two years ago, on March 16, Reba McEntire lost seven of her band members and her tour manager in a tragic plane crash after a concert.
I remember that day in 1991. I was driving to work and heard about the crash on the radio. My heart skipped a beat when I thought Reba was also on the plane.
But she wasn’t.
Reba and her band had performed in San Diego on March 16, 1991, and were heading to Fort Wayne, Indiana, for their next concert on the tour.
Two planes were waiting at the airport in San Diego. The band members and tour manager flew on ahead while Reba, her husband, and her manager stayed overnight in San Diego.
The first plane tragically crashed just ten miles east of the airport.

Over the years, Reba has often remembered her lost friends.
In a heartfelt interview with Oprah Winfrey in 2012, she talked about the day her band died.
“The tip of the wing of the airplane hit a rock on the side of Otay Mountain, and it killed everyone on the plane,” McEntire told Winfrey.
“When we were notified, Narvel (Reba’s manager) went to meet with our pilot, and he told us what had happened. Narvel came back to the hotel room where I was — it was two or three o’clock in the morning — and he said one of the planes had crashed. I asked, ‘Are they OK?’ He said, ‘I don’t think so.’ I asked, ‘But you’re not sure?’ He said, ‘I don’t think so.’”
Reba had tears in her eyes as she remembered the details of the tragedy.

“Narvel was going room to room with a phone and calling…” she began, pausing as tears filled her eyes. “I’m sorry — it’s been 20 years, but it’s just like — I don’t guess it ever quits hurting,” she said. “But I can see that room. I can see Narvel walking back and forth.”
Now, 32 years have passed since the crash. Recently, she shared a photo of her band on Instagram to remember the tragic events of that day.
In 2020, she also paid tribute to her friends.
“29 years ago today, I lost my friends in a plane crash. The timing of Mama’s passing with that anniversary seems appropriate,” she wrote.
“I know they’re all in Heaven together and taking care of each other. Let’s keep finding ways to take care of each other down here on earth and never take one moment with our loved ones for granted.”
Reba’s fans quickly offered their support to the country star. Many sent positive thoughts and prayers.
“Reba, I’ve always loved your music, our shared horse background, and now following you on Insta. Prayers for you and your mother,” one fan wrote.
In 2023, Reba showed once again that she will never forget her friends and still mourns their tragic loss.
“Their love for music and the stage gives us all the strength to go on,” she wrote, sharing a video of the group performing together.
