Food-Contact Materials and Equipment Suitability

Stainless steel grades differ, and chloride-rich brines, acids, heat and damaged surfaces can promote corrosion. Mild steel, copper alloys and aluminium may require restrictions or protective design.

Plastics, hoses, gaskets, lubricants, adhesives and coatings must be intended for food contact at the relevant temperature and chemistry. Cracking, swelling or delamination changes both hygiene and migration risk.

Smooth, durable surfaces are easier to clean, but scratches, pits, weld defects and inaccessible joints can harbour product. Suitability includes fabrication and maintenance, not only the base material.

Supplier declarations, conditions of use, material identity and replacement specifications should be retained. A vague marketing statement is weaker than a defined compliance and application record.

Inspect for corrosion, wear, odour, colour transfer, fragments and cleaner damage. Replace degraded components before they contaminate product or prevent effective cleaning.
