This document outlines the hygienic design considerations applicable for a risk-based approach to prevent contamination of food products. Entities (equipment and facilities) with poor hygienic design are difficult to clean. This document describes the principles of hygienic design that should be followed when designing, constructing and installing entities intended for food manufacturing. Guidance is provided for each of these steps to ensure that they do not adversely affect food safety and quality.
