Why Metal Detection in Food Is Not Easy

In the past year, pieces of metal originating from a conveyor system were found in ready-to-eat chicken products, metal shavings were found in a package of ground turkey, pieces of metal were embedded in a fully cooked sausage product, and one company received three complaints of metal objects in beef franks.

Why is it so hard to detect metals in food?

The same unpredictable performance can exist when trying to detect metal in food. Metal detection in food is easy when it works—but it doesn’t always work. Audits can fail, detectable metal types and sizes may not be what the food quality manager wants or, worse yet, a piece of metal can escape inside a product where a customer may find it. Clearly, an on-again, off-again contaminant detection approach is not acceptable when it comes to food safety.

 

There are key barriers to achieving 100% metal-free products

· The metal detector must find anything, anywhere in any product all the time. That can be daunting considering the volume of production from just one line in a day and all the different types of metal pieces that might be part of your factory or in the ingredients.

· Metal detectors use electromagnetic fields to find things that are magnetic and conductive. Most food products are wet, have salt or contain minerals, which when subjected to electromagnetic fields also look magnetic and conductive. Ignoring the product and finding the metal is not as easy as it seems.

 

Small metal foreign objects have very small signals, and the metal detector is operating in a factory that has many possible noise sources that can confuse the metal detector electronics and software. For example, at any given time:

· Large motors are turning on and off

· Electronics boxes are broadcasting wide spectrums of radiated noise

· Production equipment is vibrating and causing the antenna in the metal detector to move ever so slightly

· Electrical power is surging and dropping

· Temperatures are going from freezing to boiling and back again

 

These conditions affect results. As you can see, finding the needle in the haystack or a shard of stainless steel in a package of meat can be a formidable challenge.
