Doc. 52 - BASIC PRINCIPLES OF CLEANING AND DISINFECTION IN FOOD MANUFACTURING

First Edition - July 2021
Seiten /pages: 58

Summary
This guideline aims to provide a basic understanding of the cleaning and disinfection of food manufacturing equipment and their environment. It is intended to help stakeholders within a food manufacturing facility to make the correct choices when developing cleaning programs by offering guidance on soil characteristics, wet and dry-cleaning methods, as well as disinfection methods.
The guideline can also help designers and manufacturers of hygienic entities to understand the needs of end-users when specifying and building these entities.
