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.
Why More Happy Couples Prefer to Sleep in Separate Beds
According to a survey, only 14% of couples sleep in separate beds every night. And while many of us might believe in the saying “couples who sleep apart grow apart” there are studies that show the opposite is actually true.
We at Bright Side believe that there are no wrong or right sleep arrangements, because to some, sleeping in different beds can be as pleasing as for others sharing a bed with their partner.
A poor night’s sleep can turn lovers into fighters.

According to research, sharing a bed with a partner that has restless sleep behavior can deprive you of 49 minutes of sleep each night. And, when one partner doesn’t get a proper night’s sleep because of the other, it will most likely result in a conflict between them the next day.
Actually, the study even confirmed that couples who tend to have a poor night’s sleep have more severe and more frequent fights than those who wake up well-rested. People who get a good night’s sleep, on the other hand, are more likely to be in a good mood, have lower stress levels, and be more patient.
Resenting your partner because you can’t get a good night’s sleep can be destructive to the relationship.

Snoring, fidgeting, and bed or blanket hogging are just a few of many reasons why some couples choose to sleep in different beds or even in different bedrooms. Lying awake listening to your partner snoring while you beat yourself up to fall asleep can lead to a build-up of anger, tension, and resentment toward your partner.
According to Jennifer Adams, author of Sleeping Apart Not Falling Apart, sleeping in a separate bedroom can even help a relationship thrive because both partners are not sleep deprived.
Each partner can tailor their sleeping conditions to their heart’s content.

Tina Cooper, a licensed social worker, sleeps in different bedrooms with her partner because of their opposite sleeping habits. “I’m a night owl, he’s an early bird. I need soothing sounds to fall asleep, and he likes silence. He likes a hard mattress, and I like soft and full of pillows. And because I don’t like the early day’s sunlight, my boyfriend gave me the master bedroom which gets less light and he has the second largest room that gets the sunrise he loves.”

How you spend the nighttime in your shared bedroom with your partner can also influence your daytime functioning, marital satisfaction, and psychological and physical health. And when 2 people with different bedtime preferences and nighttime schedules end up together, changing themselves just to please their partner’s needs might harm their relationship in the long run.
Sleeping in different bedrooms with your partner means that the 2 of you will have a place just for yourselves where you can relax after an exhausting day. This way, both of you can satisfy your needs without tiptoeing around and worrying about whether your partner might wake up because you want to watch the latest episode of your show before bed.
Even if you don’t remember waking up, disturbed sleep can have a negative impact on your overall health.

During the night, our brain cycles through the stages of sleep several times: light sleep, deep sleep, and REM (Rapid eye movement sleep). But when you interrupt the cycle by waking up during the night, it means that your brain spends more time in the light sleep stage and misses out on REM. And without sufficient REM your emotional well-being and cognitive performance suffer.
Interrupted sleep can also have short and long-term health consequences, like hypertension, weight-related issues, mental health problems, reduced quality of life, and other health-related issues.
People on Reddit share why they decided to sleep separately with their partner.

- “Because a good night’s sleep is more romantic than sharing a bed. I snore and toss and turn. He gives off literal village levels of heat in his sleep and I can’t stand the heat. I read, he can’t stand light. We keep different hours to an extent. A million reasons. We get along so much better this way.” — crankyweasels
- “My partner and I have completely separate bedrooms. We ’sleepover’ occasionally in each other’s rooms. However, we both sleep exponentially better apart. He’s a night owl and I’m an early bird. He wants only one sheet on him, I want 10 lbs of blankets. In addition, having a separate room allows me to decorate it however I want, have my own personal space, and keep it to the level of cleanliness I prefer. People look at us sideways when I mention the separate rooms thing, but it’s been a game-changer.” — eriasana
- “Different sleep cycles due to different work schedules. We are still madly in love and we both agreed to this because it’s the best for both of us.” — AFishInATank
- “Early in our relationship, 90% of our fights occurred in the bedroom. I like to sleep in a cold room with the fan on and white noise like a box fan. I also like to go to sleep with the TV on. She likes to sleep in a warm, still, cave in complete silence and darkness. We started sleeping in separate rooms and all of a sudden 90% of our fights stopped. Also, because we were getting real sleep, other fights turned more into heated discussions.” — ttc8420
