Working in accordance with GMP (Good Manufacturing Practices) safeguards food safety and quality in the food industry. Bacteria-resistant coatings can be an additional material choice within GMP: the dry paint film is protected against bacterial degradation. This does not replace cleaning, but fits within GMP principles concerning hygiene, cleaning and material suitability.
Working in accordance with GMP: the role of resistant coatings
GMP refers to the general guidelines and standards that safeguard food safety and quality. Using a bacteria-resistant coating adds a protected dry paint film to the selected paint system. This property applies to the finish itself and does not constitute a claim that bacteria in the space, on equipment or outside the paint film are reduced.
Relevant GMP principles
There are no GMP guidelines that focus exclusively on such coatings, but several principles apply when working in accordance with GMP:
- Hygiene practices — GMP requires clean and hygienic conditions; a bacteria-resistant coating protects the dry paint film against bacterial degradation.
- Cleaning and sanitation — GMP requires regular cleaning; coatings are not a substitute for the correct cleaning procedures, but an additional material choice.
- Materials and equipment — everything that comes into contact with food must be safe and suitable; therefore assess the selected coating system on a product-specific basis for the substrate, area of use and applicable regulations.
During implementation, it is advisable to comply with applicable laws and regulations, product instructions and manufacturer specifications, and to carry out regular maintenance and inspections.
