In the food production industry, metal is one of the most commonly found contaminant materials in food. Metal can be introduced at all stages of processing of food, as it is most commonly used in the construction of machinery, handling equipment and ancillary utensils. A metal detector for the food industry can help ensure the safety and integrity of a wide range of unpackaged, packaged or bulk goods, by identifying metal contaminants during processing or packaging and helping to ensure that they do not enter food that we eat.
