  • Are lubricants, coolants, and other materials that may contact food food-grade?

Cleanability and Accessibility

  • Is equipment designed to be readily disassembled or accessible for cleaning and inspection? *
  • Are hollow bodies, frames, and dead legs eliminated or sealed to prevent ingress of water and product? *
  • Are surfaces self-draining with no areas where water or product can pool? *
  • Are fasteners, threads, and hard-to-clean points minimized on product-contact areas?

Installation and Maintenance

  • Is equipment installed to allow cleaning of the equipment and surrounding floors and walls? *
  • Is equipment maintained in a manner that protects food from contamination such as chipped paint, rust, or worn parts? *
  • Are seals, gaskets, and belts inspected and replaced before they degrade into product? *
