Common Foreign Objects Found in Food Processing — And How to Detect Them

2026-01-10

Metal Detectors

Metal detectors are effective for identifying ferrous and non-ferrous metals. However, they are limited to metal-only contamination and cannot detect non-metal foreign objects.

X-ray Inspection Systems

X-ray inspection technology provides a more comprehensive solution by detecting both metallic and non-metallic contaminants based on density differences.

X-ray systems can detect:

Metal fragments
Glass and ceramic
Stones and minerals
Bones and shells
Dense plastics and rubber

In addition to foreign object detection, X-ray inspection can also perform quality checks such as:

Missing or broken products
Weight and fill-level inspection
Product integrity verification

Why X-ray Inspection Is Becoming the Preferred Choice

As food safety regulations become stricter and product variety increases, many manufacturers are upgrading from traditional inspection methods to X-ray inspection systems. X-ray technology offers higher detection accuracy, greater versatility, and reliable performance even for packaged products, including foil or aluminum packaging.

Conclusion

Foreign object contamination can occur at any stage of food processing, but with the right inspection technology, risks can be significantly reduced. By identifying common contaminants and choosing effective detection solutions, food manufacturers can protect consumers, comply with international standards, and safeguard their brand reputation.

If you are looking to enhance your food safety inspection process, X-ray inspection systems provide a proven and future-ready solution.
