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.
If you see someone with a three-dot tattoo, you might want to get out of there fast …

Most of the time, humans are incredibly creative people that are always willing to express themselves through actions that mirror their inner emotions and ideas.
To better express their inner creativity, some people write, others construct things, and yet others use art. The act of creating something that other people can understand is more significant than the technique.
This is nothing new, really. We have nearly as much history of creation and construction as a species. Take a look around you and you’ll see artistic touches in almost everything that people have created, including simple city planning, food, clothing, and architecture.
Therefore, it should not be shocking that so many of us decide to use our own skin as a canvas.
I am speaking of tattoos, which for the past few millennia have been deeply significant in a wide variety of civilizations throughout the world. Although in the past some communities disapproved of tattoos, they are now more commonly recognized as a way for the wearer to show their individuality and soul.
Although this differs from person to person, most people who choose to have tattoos consider them to be significant in some way. Words or phrases that really resonate are prevalent, as are signs and symbols indicating a passion or interest.

The notion that the majority of tattoos have a meaning is possibly what makes this so fascinating. To put it another way, they may offer a clear or hazy window into the owner’s thoughts.
Now, it’s crucial to keep in mind that this doesn’t always imply good things. Some people wear emblems that the bulk of society despises with pride. Some people have tattoos, which could be a clear warning indication.
As an illustration, take the three-dot tattoo, which is often believed to have a direct connection to the Russian penal system. You may not be familiar with the three straightforward dots in a line that we’re talking about here, but you’ve probably seen or at least heard of people with facial tattoos—many of whom have a criminal history.

Regardless, I was… and I felt it would be great to spread the word about the meaning in case you ever come across someone sporting this kind of tattoo.
In short, the three-dot tattoo has many symbolic connotations and typically represents devotion, secrecy, and the duration of a person’s prison sentence. The actual marking, which is frequently applied to the left hand, is said to have its origins in Buddhist symbology. The dots are meant to symbolize a rejection of violence and wickedness; they are said to represent the three wise monkeys who see no evil, hear no evil, and say no evil.
The three-dot tattoo is really more frequently associated with the Russian prison system, as it is regarded as a mark for extremely serious offenders. A person with three dots may have spent up to thirty years in prison because each dot is meant to symbolize ten years of incarceration.
The three-dot symbol is another way that criminal groups can utilize their members to identify themselves. In these situations, others may interpret the tattoo as a threat or warning.

Having said that, it’s crucial that you follow your gut and exercise common sense when deciding how to respond if and when you come across someone who has a three-dot tattoo in person.
Some people may get it inked on them for cosmetic reasons without having any connection to illegal conduct at all. Some might have undergone reform and rehabilitation, making them less dangerous than they previously were.
Although it’s usually best to avoid making snap judgments, at least you’re maybe a little more prepared now!
