Les guides techniques EHEDG en Anglais

Hygienic and/or aseptic systems comprise inter alia individual components, machinery, measurement systems, management systems and automation that are used to produce for example food products, medicines, cosmetics, home & personal products and even water products. This horizontal guideline is about the hygienically safe integration of hygienic (including aseptic) systems, focusing on food production.

Systems and components are frequently put together in a way that creates new hazards, especially microbiological ones.  Deficiencies during the sequence of design, contract, design-change, fabrication, installation and commissioning are often the cause of these failures, even when specific design guidelines are available and are thought to be well understood. Errors in sequencing and content can also result in major penalties in terms of delays and in costs of components and construction. iely effectivelyuu  fficient plants and processes

This document examines integration aspects that can affect hygienic design, installation, operation, automation, cleaning and maintenance and uses system flow charts and cases describing the integration processes and decision steps.  It does not provide detailed guidance on specific manufacturing processes, products, buildings or equipment.
