Physical contamination detection in pet food can be achieved by utilizing
metal detection systems to identify metal contaminants at the start of production, in-processing and end of line.
X-ray inspection systems also detect metal, as well plastic, glass, rubber, stone, minerals, or bone. The choice between metal detection or x-ray can be down to a number of factors, including budget and the likely types of contamination as identified in the Hazard Analysis Critical Control Point (HACCP) audit. You can read more about this in our
Metal Detection, X-ray or Both Guide.
