Compliance with materials in contact with food (MOCA): EC Regulation 1935/2004 for MRO maintenance operations

Technical analysis: Food contact materials regulation (EC 1935/2004): MRO implications for food plants

Conformità ai materiali a contatto con gli alimenti (MOCA): Regolamento CE 1935/2004 per le operazioni di manutenzione MRO - UNITEC-D Industrial MRO
Analisi tecnica del Regolamento CE 1935/2004 applicata alle attività di manutenzione MRO. Guida alla conformità, checklist pratica e rischi legali per responsabili di impianto.

1. Introduction

Food safety does not only depend on the production processes, but also on the integrity of the materials used in the machinery. For a maintenance manager, understand Regulation (EC) No. 1935/2004 is essential. This European standard establishes the requirements for all materials and objects intended to come into contact with food, in order to prevent the migration of harmful substances into the food itself. A rigorous approach to MRO (Maintenance, Repair, and Operations) is critical to maintaining compliance, ensuring consumer safety and protecting the company from legal risks.

2. Scope & Applicability

Regulation 1935/2004 applies to a wide range of materials, including polymers, elastomers, metals, paints and lubricants that make up machines for the processing, packaging and transport of food products. The regulation extends not only to parts that directly touch the food, but also to components that could release substances into the production environment or through vapors and condensation.

3. Key Requirements

Compliance requires rigorous document management and compliance with specific standards for the type of material.

4. Impact on MRO operations

Integrating MOCA compliance into MRO procedures involves structural changes:

  • Sourcing: It is mandatory to purchase components only from suppliers who provide the updated DoC. Spare parts purchased without documentation must be excluded from food contact lines.
  • Warehouse Management: MOCA compliant components must be physically separated from generic industrial components to avoid incorrect use during emergency repairs.
  • Documentation: Each maintenance intervention must record the replacement of MOCA components, linking the lot number of the piece to the maintenance order.

5. Component Requirements

Not all components are the same. For the food sector:

  • Elastomers (Seals/O-rings): Must comply with specific migration tests for food contact (typically FDA 21 CFR 177.2600 or EU Regulation 10/2011).
  • Lubricants: Must be NSF H1 certified for incidental contact. Non-H1 lubricants are prohibited in processing areas.
  • Metal Components: AISI 316L stainless steel is standard for corrosion resistance and chemical inertness.

6. Maintenance Compliance Checklist

Use the following checklist for routine inspections:

  1. Check the availability of the Declaration of Conformity (DoC) for each spare part installed.
  2. Check the presence of the 'glass and fork' symbol on the plastic components.
  3. Make sure the lubricants used are NSF H1 certified.
  4. Check that the gaskets do not show any deterioration (cracks, hardening).
  5. Ensure that the stainless steel used complies with standards EN 10088.
  6. Verify that MRO cleaners are not corrosive to installed MOCA materials.
  7. Check that there are no deposits of excess lubricant.
  8. Check that the flexible hoses are marked for food use.
  9. Make sure traceability is documented in the CMMS software.
  10. Check the cleanliness of the components during assembly.
  11. Make sure that the component paints are not subject to flaking.
  12. Check the tightness of the fittings to avoid fluid leaks.
  13. Check the correct management of MOCA waste at the end of its life.
  14. Train staff on MOCA material handling procedures.
  15. Conduct periodic migration tests if required by the HACCP safety plan.

7. Common Non-Compliance Issues

Audits frequently highlight:

  • No DoC for components replaced during night or emergency maintenance.
  • Using generic (non-MOCA) gaskets for quick repairs.
  • Improper use of unsuitable lubricants (H2 instead of H1).
  • Lack of traceability between component batch and machine.

8. Sanctions and Responsibilities

In Italy, violation of the MOCA rules is sanctioned by Legislative Decree 29/2017. Administrative sanctions can exceed 30,000 euros per single violation. More serious is the criminal liability pursuant to Law 283/1962, which punishes the possession of substances unsuitable for contact with food which can alter the healthiness of the product. The responsibility falls on the company owner and the technical manager.

9. Summary

MOCA compliance is not a cost, but a necessary condition to operate in the food sector. The use of non-certified components exposes the company to unacceptable risks. To procure certified and guaranteed components, consult the UNITEC-D E-Catalog.
