Contaminants are a fact of life for food manufacturers, which makes contaminant detection a necessity. Contaminants come in all shapes and forms, including microscopic elements, such as bacteria and chemicals. Our focus is on choosing the right solution to detect physical contaminants or foreign objects, such as glass, metal, plastic, rocks, or bones. The following 5-step process is one way to calculate the payback of purchasing metal detectors or X-ray systems to detect these contaminants. We’ll look at the initial and continuing costs as well as the savings to your operation.
