Foreign Object Contamination
The presence of unintended physical materials in food products, such as metal, glass, plastic, or other debris.
What It Means
Foreign object contamination occurs when unintended physical materials are found in food products. These objects can include metal fragments from processing equipment, glass shards from broken containers, plastic pieces from packaging materials, stones or rocks from agricultural products, wood splinters, rubber fragments, insects, hair, or other debris. Foreign object contamination is a significant cause of food recalls and can result in Class I or Class II classification depending on the nature and size of the object and the potential for injury. Hard or sharp foreign objects larger than 7 millimeters are considered by the FDA to pose a choking hazard or risk of injury and typically trigger a Class I recall. Smaller or softer foreign objects that are unlikely to cause injury may result in a Class II recall. The most common sources of foreign object contamination in food manufacturing include equipment malfunction or wear (metal fragments from worn blades, screens, or conveyors), packaging material failures, inadequate supplier controls, and breakdowns in foreign material detection systems such as metal detectors and X-ray machines. Food manufacturers use a variety of prevention methods including metal detectors, X-ray inspection systems, magnets, screens, filters, and visual inspection. HACCP plans and food safety plans under FSMA specifically require manufacturers to identify and control physical hazards as part of their hazard analysis.
